Sea Stars are marine invertebrates with a central disc and usually five arms.
They are also commonly referred to as Starfish.
There are about 2,000 species of Sea Stars. Color, shape, and size varies however all resemble a star.
They possess the very cool ability to regenerate lost arms and can regrow an entire new limb given time.
They mainly live on sea floors, move at night and feed on microalgae, sponges, bivalves, snails and other small animals.
