Chocolate chip sea stars aren't picky eaters. They feed on sponges, bacteria and detritus or waste products and the remains of dead plants and animals. Since they don't have eyes, chocolate chip sea stars hunt using their sense of smell. Once they smell something they want to eat, the sea star carries itself over to its food. The mouth of sea stars is on the oral surface or underside of their body. The star covers its food, then pushes out its stomach from inside its body and covers it. Stomach juices smother the food, and cilia or tiny hairs move its now gooey meal inside the sea star's body.
