Online Zoo Amphibians

Amphibians are animals that begin their lives in the water before moving onto land when they mature.

In order for amphibians to make this change, their bodies undergo a transformation known as "metamorphosis".

During metamorphosis, amphibians switch from breathing with gills to breathing with lungs.

There are exceptions: some amphibians (for example the axolotl) never lose their gills and live their whole lives in the water.

Axolotl - an amphibian that doesn't grow up!

Online Zoo Birds

Birds are animals with wings and feathers; adaptations that allow most birds to fly.

Well-known birds that can't fly include ostriches, cassowaries and penguins.

Like reptiles, birds hatch from eggs. Scientists now believe that birds are the living descendants of dinosaurs.

Birds are found on every continent on Earth. The smallest bird is the bee hummingbird, the largest is the ostrich.

Online Zoo Fish

Fish are aquatic animals with organs called gills that allow them to breathe underwater.

Fish have fins to propel them through the water and are streamlined so that they can move using little energy.

Fish are found in freshwater and marine habitats.

There are two main types of fish: cartilaginous fish and bony fish.

The skeletons of cartilaginous fish are made of a substance called cartilage, which is more flexible than bone. Sharks, rays and skates are all examples of cartilaginous fish.

Bony fish such as cod and salmon have skeletons that are made of bone. There are more species of bony fish than any other type of vertebrate. (A vertebrate is an animal with a backbone).

Online Zoo Invertebrates

Invertebrates are animals that don't have a backbone.

Animals such as insects, crustaceans (e.g. crabs and lobsters), arachnids (e.g. spiders and mites), snails and worms are all invertebrates.

Although most invertebrates are small in size, they make up for this in numbers: over 95% of all animals are invertebrates!

Online Zoo Mammals

Mammals evolved from prehistoric, reptile-like animals around 195 million years ago.

Characteristics shared by all mammals include: being warm-blooded; feeding their young with milk; and having hair.

Most mammals (but not all, as we’ll discover with the monotremes) give birth to live young.

There are many different types of mammal. In this online zoo they have been separated into a number of groups. We start with the Carnivora...


Virtual Zoo Carnivora
  • Download a free printable Carnivora worksheet here.

Members of the order Carnivora* are mammals that all stem from a common, meat-eating ancestor. Members of the Carnivora order are called Carnivorans.

All carnivorans have a certain type of tooth, which evolved to cut through meat.

* An order is a group of related animals that can contain many different animal families and species. You can learn more about terms such as "family", "order" and "species" on this page: Animal Classification

Carnivorans are also known as ‘carnivores’, but this word can also apply to any meat-eating animal. Remember, not all carnivores (meat-eaters) are carnivorans (members of the carnivore order)!

Carnivora is split into two smaller groups, or suborders: feliforms and caniforms.

Feliforms are 'cat-like' carnivorans. As well as cats, this group includes animals such as hyenas and mongooses.

Caniforms are 'dog-like' carnivorans. This group includes dogs, and animals such as bears and seals.


Online Zoo Bears

Bears are large, powerful animals that are found in a variety of habitats in the Americas, Europe and Asia.

Most bears are omnivores, eating anything from nuts and berries to meat.

The polar bear is the only bear that is almost entirely carnivorous. By contrast, the giant panda is almost entirely herbivorous.

Cats belong to the family Felidae. Expert predators, cats are fast and agile, with excellent senses of sight and hearing.

All cats are almost entirely carnivorous and most of the "big cats" sit at the very top of the food chain wherever they are found.

Virtual Zoo Dogs

Members of the dog family Canidae, which includes wolves, foxes and jackals, are found on every continent except Antarctica.

Highly intelligent, with acute senses of smell and hearing, dogs are capable predators. Some, such as wolves, live in packs, hunting as a team to capture prey animals much larger than themselves.

Online Zoo Pinnipeds

Pinnipeds are mammals that have special adaptations for a semi-aquatic lifestyle.

With flippers for limbs and streamlined bodies, these ocean predators are skilled swimmers. However, they are slow and clumsy on land.

Leopard seal: named on behalf of its leopard-like black spots.
Online Zoo: Southern Elephant Seal
Southern Elephant Seal: the world's largest carnivoran.

Cetacea: Whales, Dolphins & Porpoises

Virtual Zoo Cetaceans

The cetaceans are a group of aquatic mammals that live their whole lives in the water.

Although fish-like in appearance, cetaceans are warm-blooded, give birth to live young, and breathe air - all characteristics of mammals.

Cetaceans evolved from even-toed ungulates, a group of hooved mammals that also includes pigs and hippopotamuses.

Virtual zoo: Blue Whale
Blue Whale: the world's biggest animal.
Orca: apex predator of the seas.

Ungulates (Hoofed Animals)


Ungulates are mammals that have hooves, and are therefore also known as ‘hoofed animals’.

There are two main types of ungulate: Even-toed ungulates and odd-toed ungulates.

Even-toed ungulates bear their weight on their third and fourth toes. This group contains animals such as pigs, hippopotamuses and deer. This group also contains the cetaceans, but these animals have evolved flippers instead of feet.

Odd-toed ungulates bear their weight on their third toes, or have an odd number of toes. Animals in this group include horses, tapirs and rhinoceroses.

Other types of ungulate include the aardvarks (Tubulidentata), and the dugongs and manatees (Sirenia).

Online Zoo Elephants

Elephants are large, powerful mammals with trunks, tusks, and thick grey skin.

The African bush elephant is the largest land animal in the world.

Until recently, scientists used to think that there were two species of elephant: the African elephant and the Asian elephant.

Today, the African elephant has been separated into two species: the African bush elephant and the African forest elephant, taking the total number of elephant species to three.

Marsupials are also known as ‘pouched mammals’. When born, their young are undeveloped, and continue to grow in a special pouch in their mother’s body.

Most of the world’s marsupials live in Australia, although some are found in the Americas.

One of the best-known American marsupials is the Virginia Opossum.

Koala: this furry marsupial is asleep for much of the time.

Online Zoo Monotremes
  • Download a free printable Marsupials & Monotremes worksheet here.

Monotremes are possibly the strangest mammals in the online zoo!

What makes monotremes different to other mammals is that they lay eggs rather than giving birth.

There are only five species of monotreme: four echidnas and the platypus.

Echidnas are also known as "spiny anteaters".
The platypus is found only in eastern Australia.

Primates is an order of mammals that includes monkeys, gibbons, lemurs, great apes, and related animals.

Primates have forward-facing eyes to judge distances, flexible limbs for climbing, and hands (and sometimes feet) that can hold onto objects.

These are all adaptations for living in trees; the ancestors of today's primates were tree-dwelling animals. Most primates still live in trees.

If you look in a mirror you’ll see a primate! Humans are members of the family Hominidae, a primate family also known as the "great apes".

Bonobo: closely related to the chimpanzee, and to humans!

There are around 2,000 species of rodent. This huge group makes up around 40% of all mammals.

Most rodents are small animals with long tails. All have long incisor teeth that never stop growing. This allows the rodent to gnaw on tough plants with no danger of its teeth wearing down.

Online Zoo Reptiles

Reptiles belong to the order Reptilia. Most reptiles are cold-blooded, egg-laying animals. Some reptiles–most vipers, for example–give birth to live young, rather than laying eggs.

Reptiles are an ancient, and highly diverse, group of animals. Although crocodiles, snakes and sea turtles are all reptiles, all are very different from each other.

In fact, some reptiles are more closely-related to animals in other groups than they are to other reptiles. Crocodiles, for example, are more closely related to birds than they are to snakes.

During the Mesozoic Era, reptiles–in the shape of dinosaurs–were the dominant land animals.

After the Cretaceous–Paleogene Extinction Event that occurred around 66 million years ago, it was the turn of the mammals to become the dominant large land animals.



Crocodilia is a group of carnivorous reptiles that includes the crocodiles, alligators, caimans and gharials.

Crocodilians are more closely related to birds than they are to other reptiles such as lizards and snakes.

Both crocodiles and birds are descended from archosaurs, a group of reptiles that first appeared in the Triassic Period.

Sea Turtles

Online Zoo Sea Turtles

Sea turtles are reptiles that are adapted to a marine lifestyle. After hatching from eggs laid on the beach, they make their way to the sea.

Sea turtles travel thousands of miles during their lives, but always return to the same beaches to breed.

The females leave the water to lay their eggs, but the males, after hatching, will never set foot (or flipper) on dry land again.

  1. Hi Admin! My name is Lacey Marie, age 13. I love Horses because there really smart and are really cute! I also love dolphins, cats and dogs. (I have 5 dogs) I don’t like sharks and bugs though!

    • Hi Gracey,

      Thank you for your comment. You’re right, big cats are similar to domestic cats in many ways. I wouldn’t want a pet lion though!
