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.
A type of marine protected area (MPA) – a part of the ocean where we've set limits (rules) around what humans can do there. Often there are some places set aside for fishing and other areas where fishing is not allowed at all. This is to protect the creatures and plants that live in that part of the ocean. The largest marine park in the world is the Great Barrier Reef Marine Park in Australia.
A fish that looks like an eel. It spends most of its time hidden in caves and rock crevices at the bottom of the ocean, with only its head stuck out. It usually comes out at night, and eats things like fish, octupuses, squid, and crabs.
A prickly fish that puffs itself up to scare away predators by swallowing water or air. It is often poisonous.
A long line of jagged rock, coral, or sand just above or below the surface of the ocean. An artificial reef is when a human-made structure creates a reef on the sea floor.
A tropical fish that can puff itself up with air or water when it feels threatened. Most puffer fish are poisonous (if you ate them you would get sick or die). Also called blowfish.
