Sis forSea Sponge
Scientific name: phylum: porifera
A sponge is an animal that lives in the sea whose body is made up of lots of holes. Most sea sponges have hard skeletons, and the holes are for filtering food out of the water and so they can breathe.
Some species of sponge have soft skeletons and people used to catch them to use them for cleaning and packaging, but there are now almost none left. Today, sponges found around the house are made by people, and are not animals caught in the sea.
Sis forSea urchin (creature)
Scientific name: class: echinoidea
Sea urchins are a small, round, spiny creature related to the starfish. They move very slowly on hundreds of small tentacle-like legs that use suction to stick to rocks. Their mouth is at the bottom of the sea urchin, and they eat algae as they move around.
Different kinds of sea urchin have different colours and different lengths of spines. The spines are hinged and can move around. Sea urchin shells don't have spines and look very different to a live sea urchin.

Sharks are a type of large fish that live in the sea. There are many different varieties of shark. Some eat smaller fish, some eat penguins and seals, and others eat the same way as large whales, by sifting out tiny sea animals from the water.
Sharks constantly grow new teeth, and can lose thousands in their lifetime. Their skeleton is not made of bone, unlike most fish and animals, but is made from something softer and more flexible called cartilage. In people, cartilage is found around the ends of our bones to make our joints easier to move.
Scientific name: ovis aries
Sheep are closely related to goats. People keep sheep for their wool and their meat. Every year the wool must be cut off the sheep so it can be used to make clothes - people who do this are called shearers.
Male sheep are called rams, female sheep are called ewes and baby sheep are called lambs. Rams grow big, curled horns as they get older.
