When an animal, such as a bird or turtle moves from one area or habitat to another at different times of year (depending on the seasons).
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 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 plant similar to grass that grows in shallow waters close to land. Seagrasses can grow into huge underwater meadows. They provide a place for young fish and other small sea creatures to live and are an important source of food for larger animals like turtles.
A group of plants, animals and other living things that live in the same place and help each other to survive.
A turtle that lives in tropical waters. It has a brown shell and got it's name because of the layer of green fat under it's skin. Green turtles used to be hunted for food and made into soup! Now, a lot more effort is made to preserve these beautiful creatures since there are not many of them left. Green turtles help maintain balance in the ocean ecosystem by eating the sea grass beds and keeping them at a healthy thickness.
