Activities

Algae

 

An organism that grows on water or damp surfaces. Algae can been so tiny you can’t see them or as big as kelp which can grow over 30 metres long! Algae can be green, brown, or red. They use sunlight to produce oxygen, like plants, and play a very important role in the ocean food chain.

Coral

 

Sea animals that stay in one place their whole life. Some coral produce a colourful skeleton (which is also called coral) that will remain after they die. Coral are often found grouped in large areas called coral reefs, and they are related to sea anemones and jellyfish.
