Brittle stars have many differerent modes of feeding. Some species are detrus feeders, meaning they feed on organic material suspended in the water (dead organisms, fecal matter). Some are carnivorous and some are suspension feeders that anchor to the bottoms with one or two arms and suspend the other arms into the water. The food sticks to brittle stars tube feet and the spines and then they use their tube feet to clean the food of the spines and bring it to their mouth.

They mainly prey on reef coral polyps and brittle sea stars. But when they are short on food, they can survive on energy reserves.
