Diagnosis. Length 30–70 mm. Color light brown to chocolate brown; ends of feet lighter, due to wear. Body form characteristic, with heavy, conspicuous tube feet confined to 5 radii. Mouth concealed by 5 prominent oral valves. Body wall rigid, with numerous ossicles consisting of buttons (45–80 μm long) with 10 knobs, and deep cups (45–55 μm in diameter).

Distribution. NC to E and W FL, Gulf of Mexico, Caribbean and Brazil.

Habitat. Intertidal or subtidal on sand and shell bottoms, also inside sponges. 0– 37m.

Remarks. Miller and Pawson (1984) note the extraordinary discovery by T.C. Shirley of several specimens of this species living deep inside sponges. No entry point was found, and it was surmised that the holothurians entered the sponges while very young, and grew in situ.
