A

Amphibians:
Are cold-blooded, soft-skinned animals which live on land and in water. They have an internal skeleton and are vertebrates. Examples of amphibians are frogs, toads and newts.

Annelids:
Annelids are worms; they have segments and have long cylindrical bodies. They have no backbone, so are invertebrates.

Arachnids:
Spiders, ticks and mites are members of this family which have no internal skeleton or backbone - they are invertebrates. 

Arthropods:
Arthropods have segmented bodies. They have an exoskeleton which means that their skeleton is on the outside of their bodies. Their legs are jointed to their bodies. An example of an Arthropod is a Crab.

B
Birds:
Birds are warm-blooded, egg-laying animals which have wings and feathers, but not all birds can fly.

C
Canines:
All types of dog and dog-like mammals are members of this group - it includes animals such as wolves, German Shepherd dogs.

Chilopoda:
These are a kind of Arthropods and include animals such as the centipedes.

Chordates:
Chordates are animals with bodies that are supported by an internal skeleton including a stiff rod which is called a notochord.All such animals are also called vertebrates.

Cnidarians:
They live in water and have a sack-like body. Their body has a single opening. An example of an Cnidarian is a jellyfish.

Crustaceans:
These are a kind of Arthropods and include animals such as crabs and woodlice.

D
Diplopoda:
These are a kind of Arthropods and include animals such as the millipedes.

E
Echinoderms:
Have spiky skin and suckers. They have five-rayed body. An example of an Echinoderm is a starfish.

Exoskeleton:
An animal with an exoskeleton has its skeleton is on the outside of its body. Such animals include insects.

F
Felines:
All types of cats and cat-like mammals, such as tigers, tabby cat, leopards and lions, are examples of felines. They have a backbone, so are vertebrates.

Fish:
Fish are animals that live in water. They have scales and fins to swim with and have gills to breathe with. They have a backbone and so are vertebrates.

Flatworms:
They also are worms but their bodies aren’t split up into segments, they are also flat- hence the name.

I
Insects:
Insects are the most numerous type of Arthropod on earth. They are animals with an exoskeleton and no more than three pairs of true legs - though some of their caterpillars have pretend legs called prolegs. They are invertebrates and include beetles, butterflies and ants.

Invertebrates:
Invertebrates are animals which do not have any backbone.

M
Mammals:
Mammals are warm-blooded creatures that have backbones.  They suckle their young animals with milk - we are mammals!

Molluscs:
Molluscs have soft bodies. Most Molluscs have shells, an example of a Mollusc is a snail, slug or mussel.

N
Nematodes:
Nematodes are worms with no segments.

P
Primates:
Primates are monkeys or apes which have hands and feet which grip. They are the closest relative to the human and, like us, are mammals.They have a backbone, so are vertebrates.

R
Reptiles:
They are scaly, cold-blooded creatures which lay eggs on land. Examples of reptiles include Smooth Snake, Grass Snake and Adder.

Rodents:
Rodents are mammals with long front teeth which are good for gnawing, like mice and moles. They have a backbone, so are vertebrates.

V
Vertebrates:
Chordates are animals with bodies that are supported by an internal skeleton including a stiff rod which is called a notochord. All such animals are also called vertebrates.

Vulpes:
All types of foxes are examples of the vulpes. They have a backbone, so are vertebrates. They also have fur and give birth to live young which are suckled on milk - another example of mammals.
