Holothuriidae
Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 0 - 250 m (Ref. 85345). Subtropical
Atlantic and the Mediterranean Sea: Algeria.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 20.0 cm TL male/unsexed; (Ref. 358)
Maximum size: 20 cm. Body: with more or less round cross section; is provided with the ventral face with 3 lines with podia with suction cups. Tegument: constellated with multiple papillae. Color: supported black; papillae being very of an immaculate white. Absence of tubes of Vat (Ref. 358).
Maximum size: 20 cm. Species presents the small funds until largest the depths, but rare. Habitat: Hard funds and herbaria. Biology: this species is nourished, using its tentacles oral flattened, of various organic fragments. It (charges) literally elements of the ground in its oral opening, located at the back of the body. The animal sorts the edible organic substances, and rejects the elements not metabolized such as sand, in the form of roved excrements (Ref. 358).
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.
