Short description Morphology

Mean live weight 700 to 1,300 g; body-wall thickness 0.4 cm. Body sub cylindrical, arched dorsally (bivium) and slightly flattened ventrally (trivium). White conical papillae sparsely distributed on bivium; podia on trivium long and large, their calcareous disc around 240 micrometer in diameter. Mouth ventral, surrounded by 25 large, black brown dots and numerous small black spots; trivium grey, also with small black spots. Spicules on dorsal and ventral tegument with pseudo-tables and rosettes; pseudo-tables consisting of large base with a large hole, and a spiny spire; rosettes numerous, those in the tegument simple, but more complicated in the dorsal papillae and ventral podia; also present around anus are rods, small plates, and tables with very spiny crown; tentacles containing a few rods and large plates derived from rosettes.

Maximum depth from Ref. 85218. Not harvested for bêche-de-mer production (Ref. 122).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Members of the class Holothuroidea are gonochoric and have only one gonad. Spawning and fertilization are both external and some exhibit brooding. Life cycle: Embryos develop into planktotrophic larvae (auricularia) then into doliolaria (barrel-shaped stage) which later metamorphose into juvenile sea cucumbers.
