Main Ref. Kerr, A.M., K. Netchy and A.M. Gawel, 2006
Remarks Found on sandy areas (Ref. 115900) surrounded by corals (Ref. 129602). During the day, this species is found under rubble on reef flats, while at night it starts being exposed and becoming active. Disturbance causes this species to eject copious amounts of Cuvierian tubules (Ref. 85218). Conveyor belt-feeder (Ref. 108108), meaning it ingests the substrate's surface and defecates on it (Ref. 115242). Inserts itself in cavities beneath coral colonies during the day along with other Holothuroids (Ref. 129602).
