WhyReef - Fun Facts
The harlequin shrimp is a small shrimp, popular in aquariums because of its beautiful colorful patterns. It is only about 2 inches (5 cm) big, but don’t let its size fool you— it is a predator. Harlequin shrimp hunt in pairs for sea stars, flipping them on their back so they can’t crawl away. The shrimp then drag the sea stars alive to their dwelling-place on the reef, so they can eat them in the comfort of their own home.
