This Sea Cucumber has a dark gray to black upper surface with deep folds and a rough texture, often looking like donkey dung scattered on the seafloor. Its underside is pink to white and covered with small brown tube-like legs.

The Donkey Dung Sea Cucumber is usually found in sandy areas, where it moves slowly and rests on the seafloor. It is active at night, crawling over sandy or seagrass areas and feeding on detritus, a mix of dead plants, animals, and other tiny particles, helping to clean the ocean floor.
