Sea stars represent one of the most diverse groups of animals in the sea. Their name comes from the typical five-point shape of a star. And while most starfish species have five arms, some can have many more than that. There are over 1,500 known species that can be found in a variety of shapes and colors. Some sea star species are even poisonous. The images in this gallery have been hand-selected by Sea and Sky for their visual beauty and represent some of the most amazing images of sea stars.
