What is a starfish?
Starfish live in the ocean on the sea floor. Many starfish live in deep water, others live in shallow water. Often starfish are also called sea stars.
There are over 1500 different species of starfish. Most are predators. They eat mussels clams and occasionally, they may even catch small fish.
Starfish are invertebrates but they do have a skeleton. They do not have any blood or a brain. Instead of blood, filtered seawater pumps around their body.
Starfish are salt water animals with five arms. Salt water is the kind of water found in the world's oceans. They can come in many different kinds of colours and patterns.
The area which the arms of the starfish is attached to is called the central disc.
