Sis forScuba diving
Scuba diving is a sport where you swim deep under the water, with a supply of breathable air carried down under the water with you. Scuba divers wear wetsuits to keep them warm when they are under the water.

A sculpture is something made by people that looks interesting. Sculptures can be any size and made out of almost anything. Small sculptures are often made from clay and large ones are often made from stone or metal.
Sculptures are similar to statues, but often sculptures are abstract, which means they are interesting to look at but you can't tell what they are supposed to be, or they are deliberately made to be not an accurate copy of whatever the sculpture is supposed to be of.
A group of squirrels is called a scurry or a squad.
A scythe is a long-handled tool that is still used in some parts of the world to mow grass. Modern machinery is used today instead of scythes for the same job.
Today, the scythe is associated with death and the Grim Reaper.
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.
