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.

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.

Seagulls are very common birds that live near the sea. They have webbed feet so they can paddle in water. Gulls catch and eat fish and will also scavenge for dead fish and trash people have thrown away.
Seagulls are very common on rubbish dumps and garbage tips.
