There are over 2,000 different species of brittle stars worldwide. Many of the arms are forked. Brittle stars that have multiple-forked arms are called basket stars. They have a hard exoskeleton and vary in color. Tube feet located along the arms sense light and smells.
Some brittle stars can also kill small animals.
The mouth has five teeth. Without our visitors' support, Enchanted Learning would soon be off-line.
