S is for Spider

Spiders are a kind of animal known as an arachnid, and they are related to the scorpion. All spiders have a head, body, eight legs and no wings. Spiders come in a variety of colours, but most are brown or grey. They range from so small you can hardly see them, right up to the size of a plate.

S is for Squid

Squid are sea creatures related to the octopus and cuttlefish, which all have eight legs.
Squid move by sucking water into the top part of their body and squirting it out in a jet. They can also squirt ink into the water to confuse anything that is trying to eat it.
The squid in the photo are being cooked on a barbeque.

S is for Starfish

The starfish, or sea star, is not a fish - starfish have no skeleton. They are related to sea urchins. As they have no skeleton and hence no legs, they don't move around by walking. They move by pumping water around through tubes on the base of their arms. Not all starfish have five arms, some have more.
Starfish eat sea creatures with shells that move slower than it does. Starfish have two stomachs, and one of them can be put outside the starfish's body. So they eat clams and other shellfish by forcing them open and putting their stomach inside the clam's shell.
Some starfish can regrow arms if they are cut off. Some starfish can grow from the cut-off arm as long as some of the central portion of the starfish is still attached.
Starfish send their eggs out to drift into the open sea where they hatch into small swimming larva. When the larva are old enough, they sink to the bottom of the sea and turn into adult starfish.

A tarantula is the name for a group of several species of spider. Tarantulas are very large, and very hairy - they are big hairy spiders! Some people keep them as pets.

T is for Termite

Termites are insects that live in large colonies. They eat mostly dead plant material, like dead wood or fallen leaves. If they get into your house they may do serious damage to the frame of your house, so people treat their houses with barriers or poison to stop termites getting in.

T is for Tick

Ticks are parasitic arachnids. The live off the blood of animals. They often spread diseases as they move from host to host.

Woodlice breathe through gills like fish, which is why you often find them in damp places. Some types of woodlouse can roll themselves up into a tight ball.

W is for Worm

Earthworms live under the ground in your garden. They eat fallen leaves and make the soil better for plants to grow in. Worms are slimy, to help them travel through the soil.
