This echinoderm who some have dubbed “c*cktopus” and “pentad*ck” has five arms and each end has an eye-catching bulbous tip. The Indo-Pacific region is often where one may find choriaster sea stars, including places like the Philippines and the Great Barrier Reef. Choriaster sea stars have a distinctive, bright purple or pink color… with a little different shade of pink at the tips of their extremities. These sea stars are often found in shallow waters, where they feed on a variety of small invertebrates and organic matter. While it does look like it would like to bang you five times, it’s harmless to humans.
