Sea Stars

Sea Stars

Where in the world?

Sea Stars are found throughout the world’s oceans.

 

Animal Facts:

Sea Stars and their relatives, Sea Urchins, are in the phylum Echinodermata. The word “echinoderm” means “spiny skin” in Ancient Greek.

Some Sea Stars have the ability to regenerate appendages. If an arm is torn or cut off, some Sea Stars may grow another. Some species may even grow a new body from the severed arm! Full regeneration may take months or even years.

Sea Stars eat a variety of prey items, including mollusks, crustaceans and fish.

 

Did you know?

Some Sea Stars have a unique method of eating; they wrap their arms around their prey, then eject most of their stomach out of their body. The stomach engulfs the food while releasing enzymes to begin digestion before it is retracted back into the Sea Star’s body.
