Shape is a reminiscent of a medusa that resembles a jellyfish. Body conical, which supports an enormous umbrella-like veil. The veil extended anteriorly, composed of 12-16 large webbed podia. Body wall transparent and pigmented pale violet or pink.
Only known truly pelagic holothurian, floating or drifting near seafloor or high in the water column (Refs. 109722, 129602). Also known as a swimmng sea cucumber, it is found in low oxygen areas and is assumed as a tactic to avoid predators that are more oxygen-hungry and could easily suffocate (Ref. 127487). Feeds on resuspended sediments or detrital material from shallower depths (Ref. 109722).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | 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.
