The Stichopodidae are a family of sea cucumbers, part of the order Synallactida. Description Members of this family are mostly large or medium-sized holothuroids with an angular body shape (almost forming a squarish cross-section), a flat ventral surface, and large, fleshy, cone-shaped projections. Their mouths are surrounded by 20 peltate tentacles. They are usually found on soft substrates, such as fine sand or very fine rubble.
