Designed for kids to learn about frogs and their life cycles, as well as their habitats, characteristics, diet, etc.
Special mention of a few native New Zealand Frogs is made.
Charles Robert Darwin was undoubtedly the first naturalist who put the idea of Organic evolution on sound footing.
His statements and theories were based upon practical experiences and large number of proofs which he collected directly from the nature.
He devoted his whole life for the purpose of finding out proofs in support of the theory of organic evolution.
This document describes the characteristics of chordates and their classification. It notes that chordates possess pharyngeal slits, a post-anal tail, and a notochord. Chordates are divided into invertebrate chordates, which retain the notochord throughout life, and vertebrate chordates, which replace the notochord with vertebrae. Vertebrates are further divided into seven classes - Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. Mammals are the only group to possess mammary glands and are divided into three subclasses - Monotremata, which lay eggs;
A vertebrate is an animal with a spinal cord surrounded by cartilage or bone. The word comes from vertebrae, the bones that make up the spine. Animals that are not vertebrates are called invertebrates. Vertebrates include birds, fish, amphibians, reptiles, and mammals
This document summarizes the key characteristics of tunicates (urochordates). It describes their habitat and habits, physical features, organ systems, life cycles, classification, and major orders. Tunicates are exclusively marine animals found around the world in oceans and seas. They can be solitary, colonial, or form aggregates. Their adult bodies are sac-like and lack segments or appendages.
Marsupials are mammals whose young develop in pouches. Examples include kangaroos, koalas, wombats, and Tasmanian devils. Kangaroos have strong tails and legs to jump long distances. Koalas mainly eat eucalyptus leaves and sleep 16-18 hours a day due to low metabolism. Wombats dig burrows with claws and teeth. Tasmanian devils are the largest carnivorous marsupials and get their name from loud fighting noises. While Australians may joke about dangerous "drop bears," these do not actually exist.
Types of egg, Classification of eggs, Structure of frog egg, Structure of chi...SoniaBajaj10
The document discusses different types of eggs based on various classification schemes. Eggs can be classified based on the amount of yolk present as alecithal (no yolk), microlecithal (small amount of yolk), mesolecithal (moderate yolk), or macrolecithal/megalecithal (large amount of yolk). They can also be classified based on yolk distribution as isolecithal (uniform), telolecithal (concentrated at one pole), or centrolecithal (yolk at the center). Additionally, eggs are classified as mosaic (development predetermined) or regulative (development not predetermined), and as cleidoic (hard shell) or
Peripatus is a genus of nocturnal, carnivorous velvet worms found in Central and South America. They live under rocks and wood in tropical regions. Peripatus have cylindrical, segmented bodies with 14 pairs of appendages along their sides. They exhibit traits linking them to both annelid worms and arthropods, making them an important example in evolutionary biology.
Reptiles are vertebrates that lay eggs and have scales covering their bodies. They are cold-blooded and breathe with lungs. While some reptiles have four legs, others have no legs or shells. Common reptiles include crocodiles, alligators, turtles, tortoises, snakes, lizards, chameleons and iguanas.
Scorpions are poisonous arachnids found in tropical and subtropical regions. They are nocturnal predators that hunt insects and spiders. Scorpions have a segmented body with a cephalothorax, pre-abdomen, and post-abdomen. They have pedipalps that end in claws used to capture prey and inject venom. Scorpions breathe through book lungs and reproduce viviparously, with the young riding on the mother's back for about a week after birth.
1) Birds are warm-blooded vertebrates with lightweight skeletons adapted for flight. Their forelimbs are modified as wings and their sternum and shoulder girdle attach flight muscles.
2) They are covered in feathers and have a beak with no teeth. Their bones contain airspaces connected to lung air sacs, making them light enough for flight.
3) Birds are classified into two subclasses: Archaeornithes, now extinct birds with primitive wings that could fly little, and Neornithes, living and extinct modern birds, divided into flightless ratites and flying carinates.
1. Cleavage is the first phase of embryonic development after fertilization where the fertilized egg undergoes rapid, indirect cell divisions (mitosis) without an increase in overall size to form a multicellular embryo.
2. The pattern of cleavage depends on how much yolk is present in the egg. Eggs with little yolk (isolecithal) undergo total cleavage (holoblastic), while eggs with more yolk have partial cleavage (meroblastic).
3. In amphibians, which have mesoleithal eggs, cleavage is initially equal but becomes unequal with larger vegetal and smaller animal cells. This leads to the formation of a blastula with a fluid-filled cavity (
This document provides information about the class Aves (birds). It discusses the key characteristics of birds like feathers, warm-bloodedness, and modified forelimbs as wings. It outlines the two subclasses of birds - Archaeornithes and Neornithes. It also describes several orders of birds like Anseriformes (waterfowl), Apodiformes (swifts and hummingbirds), Charadriiformes (shorebirds), Columbiformes (doves and pigeons), Falconiformes (birds of prey), Galliformes (chicken-like birds), Passeriformes (perching birds), Piciformes (woodpeckers and toucans), Procellariifor
This document discusses various forms of parental care exhibited by amphibians to increase offspring survival. It outlines nine types of parental care observed in amphibians: 1) selection of safe egg-laying sites, 2) frothing of water around eggs, 3) defending egg territories, 4) building nests from mud, leaves, or plant shoots, 5) direct development from egg to juvenile, 6) carrying eggs attached to the body, 7) carrying larvae between water bodies, 8) brooding eggs in vocal sacs or pouches on the back, and 9) retaining eggs internally in a uterus for viviparous development.
Bird adaptations are key to their survival. Their feathers provide insulation, protection from UV rays, and help with waterproofing. Feather color also aids camouflage and sexual display. Bird wings and beaks have evolved different shapes suited to various environments and diets. Wing shapes like long and pointed aid gliding, while short and wide allow quick takeoffs. These adaptations give birds advantages for tasks like soaring, flying long distances, or grabbing food.
Herdmania is a genus of sea squirt found in shallow waters. It is a hermaphroditic chordate that is pinkish in color, around 9.5cm long, 7cm broad, and 4cm thick. Fertilization is external and its development is indirect, starting as a free-swimming tadpole larva. The presentation provides an overview of the classification, anatomy, and life cycle of Herdmania.
The scientific name of Animals is “Animalia”. The animal kingdom is also called as “ Metazoa” or “fauna”.

The document discusses the development and modifications of aortic arches across vertebrates. In early embryos, most vertebrates develop 6 pairs of aortic arches that connect the dorsal aorta to the ventral aorta and carry blood to the gills. Over evolution, there is a reduction in arches as respiration moves from gills to lungs. By adulthood, mammals and birds typically have 3 pairs of arches - the third becomes the carotid artery, fourth becomes systemic arteries, and sixth becomes pulmonary arteries.
Mammals are vertebrates that have hair and breathe through lungs. They are viviparous, meaning they give live birth, and produce milk to feed their young.
Frogs lay eggs that hatch into tadpoles and eventually frogs. They live near bodies of water like lakes and ponds to keep their skin moist and survive. Frogs eat small animals like bugs and worms, catching them with their long, sticky tongues. They jump in water to hide from predators and escape quickly by jumping. Male frogs croak to attract female frogs for mating.
The document provides information about different types of frogs, including where they live, what they eat, and examples of tree frogs and spotted frogs. It notes that tree frogs live in trees in rainforests and have green skin to camouflage with leaves, while spotted frogs live in mud and have brown skin to blend in with mud. Both are types of frogs.
This document provides an interactive lesson about frogs that teaches students about their adaptations, life cycle, diet, and defenses.

Additionally, it covers irregular past participles and provides exercises for students to practice using and distinguishing between the present perfect and simple past tenses.
Organisms have different methods of reproduction. To tell the truth, these different reproductive methods are the factors that divide animals into two categories: viviparous and oviparous animals. But more on that in a bit, here's a blog on the many different animals that lay eggs!
Do you want to know about animals that lay eggs?
Nature's way of maintaining the ecological balance on earth is something special. For example, Mother Nature has endowed living animals with the ability to go through the process of labor to directly give birth to their own kind.
Whereas, oviparous animals lay eggs that give birth to young as soon as they hatch.
Now, if you are stuck wondering because nature has allocated different reproductive processes to different animals, then we are just as clueless as you!
However, you can acknowledge the fact that every process created by nature is purposeful. For example, if nature has given birds the ability to lay eggs to produce their offspring, it may be for their own benefit.
The main reason for this is that birds cannot fly while carrying the weight of their young. By laying their eggs in a remote location, they thereby safeguard both themselves and their offspring.
We also understand how interested you are in learning about the ovoid animal species.
So, read on to know more about the complex egg-laying process and a description of the top 13 animals that lay eggs.
Animals That Lay Eggs
If we were to list all oviparous animals, you would get tired of reading the never-ending list!
A large number of prominent species in the animal kingdom are oviparous, including insects, birds, amphibians, reptiles, fish and even some mammals.
So, if you are ready to know about 13 animals that lay eggs, connect with us!
Birds
Birds are the first members of our list of animals that lay eggs. Birds are the most lively and colorful species of the animal kingdom, somewhat related to the ancient family of reptiles, the dinosaurs.
They are a very unique creation of nature because they are the only animals with feathers that are known to exist on Earth. These warm-blooded vertebrates are also known to be closest to reptiles due to the rough shape of their feet.
The largest birds alive today are the North African ostriches, which can reach 9 feet in height and weigh up to 350 pounds. The ostrich egg is the largest of any other bird species.
On the other hand, the smallest extant birds are Cuban native hummingbirds weighing less than 3 grams.
Also, the bird's feathers make them stand out among every other species.
However, having wings does not guarantee a bird's ability to fly. There are several flightless birds, including penguins, kiwis and ostriches, which, although they have wings, cannot fly due to some evolution that took place over the years.
Also, bird eggs have a hard shell that ensures safety and are laid in secluded areas like bird nests, such as a treetop or an abandoned room. The parents fulfill the responsibility of taking care it...
- Most fish breathe through gills and have skeletons made of bone or cartilage. They propel themselves through water using tail fins and other fins. Fish come in a wide variety of sizes, from less than an inch to over 60 feet long.
- Reptiles are air-breathing vertebrates covered in scales that lay eggs. Examples are crocodiles, lizards, snakes, turtles, and tortoises. They are often cold-blooded and regulate temperature behaviorally.
- Birds are feathered flying animals with wings, beaks, and lightweight skeletons adapted for flight. Their respiratory and skeletal systems are specialized for flying.
This document provides an overview of amphibians including their characteristics, evolution, examples of different types of amphibians like frogs, salamanders, and caecilians. It discusses their anatomy, life cycles, habitats, defenses, diets, and more. Amphibians are defined as animals that develop outside the body, have glandular skin without scales, and can breathe through gills or lungs. They first appeared around 340-270 million years ago.
This document provides an overview of different animal species from around the world. It begins by discussing the diversity of animal breeds and characteristics. It then examines key groups like mammals, birds, fish, and reptiles. Some specifics covered include mammals giving birth and nursing their young, while birds lay eggs. It also looks at predators that hunt other animals and herbivores that feed on plants. Finally, it profiles 10 unusual animal species, ranging from the poodle moth to the Japanese spider crab.
Esta presentación ha sido elaborada para alumnos de 5º de Educación Primaria, en el área de Ciencias de la Naturaleza (Science). Con ella, podrán conocer los diferentes tipos de vertebrados que existen y poder estudiarlos de una forma motivadora y sintetizada.
This document provides information about reptile movement, diet, reproduction, anatomy, and adaptations. It discusses how different reptiles like lizards, turtles, alligators, and crocodiles move in various ways depending on their environment. It also addresses what reptiles eat, how they reproduce, their general body structure including skin, heart, lungs, and temperature regulation. The document seeks to educate about reptiles and answer reader questions on their role in the food chain, history, adaptations, and unique species.
This document classifies and describes the key characteristics of vertebrates and invertebrates. Vertebrates include mammals, fish, reptiles, birds and amphibians, and can be found around the world. They are divided into groups based on traits like whether they lay eggs, have feathers or fur, breathe through lungs or gills, and how they regulate their body temperature. Invertebrates make up 97% of animal species and lack backbones, including insects, worms, sponges, jellyfish, starfish, mollusks and arthropods. They are grouped by their exoskeleton, body structure and environment.
Reptiles and amphibians are both vertebrates but have key differences. Reptiles are ectothermic, have scaly skin or shells, lay eggs on land, and do not undergo metamorphosis. In contrast, amphibians are ectothermic, have permeable skin, lay eggs in water, and go through a larval stage and metamorphosis. The document provides examples of different reptile and amphibian groups and describes their characteristics.
The document discusses various animal adaptations for survival. It describes how elephants' trunks are used for tasks like drinking, communication and feeding. It also notes that elephants' large ears help keep them cool in the hot African climate. Giraffes' adaptations like camouflage coats and long necks help them survive on the African savanna. Geckos have special feet that allow them to climb and sharp teeth to eat insects. Kangaroos can go without water and hop at fast speeds to escape predators in Australia. Sharks have keen smell and denticles instead of scales.
The document discusses various animal adaptations for survival. It describes how elephants' trunks are used for tasks like drinking, communication and feeding. It also explains how elephants' large ears help cool their bodies. Giraffes' long necks allow them to reach tall trees, while their patterns help camouflage them. Echidnas use spines and burrowing to defend themselves. Geckos have feet that cling to surfaces and drop their tails to escape. Kangaroos can hop fast for defense and conserve energy. Sharks have keen smell and denticles instead of scales.
There are over 6,800 reptile species including alligators and crocodiles, turtles and tortoises, snakes, and lizards. Reptiles are ectothermic vertebrates with scaly skin and internal skeletons. They lay shelled eggs and undergo little development from hatching to adulthood. Amphibians include over 4,000 species of frogs, salamanders and caecilians. They are also ectothermic vertebrates but have permeable skin and undergo metamorphosis from aquatic young to terrestrial adults. Both groups shed their skin and use environmental heat to regulate their body temperature.
The document summarizes different types of animals. It discusses that there are two main types: vertebrate animals which have a skeleton, and invertebrate animals which do not have a skeleton made of bones. It also describes characteristics of specific animal groups like mammals, fish, amphibians, reptiles, birds, worms, mollusks and insects.

Frogs are a diverse group of mostly carnivorous amphibians found around bodies of fresh water worldwide except Antarctica. They are cold-blooded animals whose temperature matches their surroundings. Frog reproduction begins when females lay thousands of jelly-coated eggs in water. The eggs hatch into tadpoles, which have gills and tails. Over several weeks, tadpoles grow legs and lungs through metamorphosis and emerge from the water as juvenile frogs.
This document provides a classification of animals, dividing them into vertebrates and invertebrates. Vertebrates include mammals, fish, reptiles, birds and amphibians, which are further defined by their key characteristics such as how they reproduce, regulate body temperature, breathe and move. Invertebrates make up 97% of the animal kingdom and lack backbones, including sponges, corals, jellyfish, worms, starfish, mollusks, arthropods and insects. They are grouped according to their physical traits and structures.
The document provides information about mammals and dolphins in particular. It discusses how mammals share common characteristics like mammary glands to feed young. Dolphins are classified as mammals that live entirely in water and have modified appendages for swimming. The document also discusses hippopotamuses, describing their aquatic lifestyle while also grazing on land at night.
The document discusses the lifecycle of frogs. It begins in the water, with female frogs laying eggs protected by jelly. The eggs hatch into tadpoles that breathe with gills and eat as they grow. Tadpoles eventually grow legs and lose their tails, becoming froglets that can breathe on land. Finally, the froglets mature into adult frogs that live on land and have fully developed lungs and limbs.
The document discusses the lifecycle of frogs. It begins in the water, with female frogs laying eggs protected by jelly. The eggs hatch into tadpoles that breathe with gills and grow while swimming. As the tadpole develops legs and lungs, it becomes a froglet, still with a partial tail. Finally, the tail disappears and the frog can live on land as an adult that breathes with lungs. Throughout its lifecycle, the frog transforms from an aquatic egg and tadpole to a terrestrial adult.
Animals and Adaptation discusses how animals adapt both structurally and behaviorally in order to survive in their environments. It provides examples of structural adaptations like thick fur coats and behavioral adaptations like moving in large groups. The document then focuses on penguins, describing their structural adaptations like dense feathers and behavioral adaptations like huddling in large groups to stay warm. It notes that while penguins' structural adaptations help with things like insulation and camouflage, their behavioral adaptations of returning to the same breeding locations make them vulnerable to predators.

2. Frogs are Amphibians…
Frogs belong to a group of animals called amphibians. (am-fib-ee-anz).
Amphibian means two-lives. Frogs begin their lives in the water as eggs and
then tadpoles and when they are fully developed they live on land. Scientists
believe that there are more than 4,000 different kinds of amphibians on Earth.
Toads, newts, salamanders and caecilians (blind worms) are also members of
the amphibian group.
3. Frogs are cold-blooded…
Frogs are cold-blooded which means that their bodies are the
same temperature as the air or water around them. When they
are cold they will lay in the sun to warm up and when they get too
warm they will go into the water to cool their bodies off.
4. Where do
frogs live?
Frogs are found all over the
world, and in every climate,
except Antarctica. They can be
found near any, and every, body
of fresh water but prefer ponds,
lakes, and marshes, because the
water doesn’t move very
fast. Frogs cannot live in the sea
or any salt water.
Scientists have found frogs
fossils that date back to the
Jurassic period over 140 million
years ago.
6. Jelly covered
Eggs…
Frogs begin their lives as
tadpoles that are hatched in
the water from tiny jelly-
covered eggs. The mother
frog can lay thousands of
eggs at one time. Imagine
having thousands of brothers
and sisters!
Tadpoles don't have eggs but frogs

7. Tadpoles…
Tadpoles are born with gills, just like a fish, so that they can breathe
under water. They have a big head and a long tail. They definitely do
not look like frogs, yet! Tadpoles have a tough life. It’s a good thing
they are fast swimmers to escape the many other creatures that hunt
them in the ponds and lakes. They are a favorite food to fish and
water beetles.
8. Metamorphosi
s
Metamorphosis is the change
of shape during an animal’s
life. During metamorphosis
the tadpole will develop back
legs first, then front legs.
Around 6 weeks of life the
mouth starts to widen.
Sometime around 10 weeks
the froglet’s, as it is now
called, eyes start to bulge out
and the tail begins to shrink
and eventually disappear.
When the lungs finish
developing the froglet makes
it’s way onto the land and, Ta-
da! It’s a frog!

After four weeks, the tadpole The tadpole's gills disappear and
grows two hind, or back, legs. its lungs grow stronger.
The tadpole's gills move inside its Two front legs grow where the
body. gills were.
10. What do
they eat?
Frogs are carnivores, which
means that they will eat meat.
Small to medium sized frogs
eat insects such as flies,
mosquitoes, moths and
dragonflies. Larger frogs will
eat larger insects like
grasshoppers and worms.
Some large frogs will even eat
small snakes, mice, baby
turtles, and even other
smaller frogs!
11. What about that tongue..?
Frog’s tongues are attached to the front of their mouths rather than at the
back like humans. When a frog catches an insect it throws its sticky tongue
out of it’s mouth and wraps it around its prey. The frog’s tongue then snaps
back and throws the food down its throat.
12. Characteristic
s
Frogs have very good
eyesight. They bulge out the
sides of their heads in order
for the frog to see in nearly all
directions.
Frogs also have an amazing
sense of hearing. You can
often tell the difference
between a male and female
frog by the size of their
eardrum, which can be seen
behind their eyes. If the
eardrum is smaller than the
eye, the frog is a female. On
males their eardrum is the
same size as the eye.
13. Characteristic
s
Frogs have very powerful
back legs and webbed feet
that help them jump great
distances, as well as, swim.
Frogs even use their legs to
dig, or burrow, underground
for hibernating (although not
all frogs hibernate!)
Every different species of frog
has his or her own look. They
come in many colors, patterns
and sizes.
17. Predators
…
Frogs have many predators.
Animal predators include
birds, fish and reptiles.
Some frogs are very good at
camouflaging themselves so
that they blend in with their
environment, making it harder
for their enemies to find
them. Some frogs can
change the colour of their skin
depending on its
surroundings.
18. Human
Danger…
Humans have become a
major danger for amphibians
of all types. Water pollution is
causing many deformities in
frogs as well as poisoning
them, and loss of habitat
through the building of roads
and houses.
In some countries, frog’s legs
are considered a delicacy,
which means that people love
to eat them! Eew!
(Pictured is the native Maud
Island Frog)
19. New Zealand Native
Frogs
New Zealand has 4 native frog species.
Frogs are declining everywhere in the world. More than most creatures,
frogs are sensitive to disease, pollution, chemical poisons and
environmental changes, as they absorb many things through their sensitive
skin.
New Zealand’s, Hamilton's frog (pictured) is the most critically endangered
species, with less than 300 individuals remaining.
