Holothuroidea | Aspidochirotida
Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 5 - 800 m (Ref. 93433), usually 100 - 299 m (Ref. 93433). Subtropical
Atlantic and the Mediterranean: Antilles to Gulf of Mexico and Canary Islands to Ireland.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 35.0 cm male/unsexed; (Ref. 363)
Maximum size: 35 cm (Ref. 363); 30 cm (Ref. 358). Maximum width: 7 cm (Ref. 363). Body: depressed enough with a side fold 5 cm pink power station (Ref. 363); definitely flattened form; is provided with the ventral face with 3 lines with podia. Dorsal tegument: Roughcast wart outgrowths and appendices; the papillae, of big size and white color; being limited to the periphery. Variable coloring, of brown with nuance of yellow to red, the sides being constellated with maculae possible blanches.
Maximum size: 35 cm (Ref. 363); 30 cm (Ref. 358). Methods: Captured by dredgers and trawls, this species is used in some countries of the zone (France, Spain where it is very appreciated in Catalonia). One needs additional information on the mode of Net use carrying of large papillae and separating the faces dorsal and ventral (Ref. 363). Habitat: Benthic species very common being from 5 to 800 m of depth at least on argillaceous and detrital funds (Ref. 363); sandy funds with muddy, partly entremélés of coralligenous. Present in low depths, the species, however, is not represented in certain sectors of the southernmost Mediterranean and occidental. Biology: Nourishes various organic fragments, "charging the elements of ground in its oral opening, located in ventral position, using its tentacles oral of flattened form. The animal rejects the fraction not metabolically (sand, sediments). When they feel threatened, they expel their internal organs which will be regenerated in the species from 2 to 3 weeks. The digestive caecums or the respiratory tree of these animals frequently shelter Fierasfer acus, a syngnathe; 15 cm; parasitic fish does not benefit solely from the constant well oxygenated water flow which feeds the water-bearing channels. Youthful phase, the fish leaves them by boring one opening in order to gain the digestive tract, where it nourishes according to any probability at the expense of sexual glands of the sea cucumber. It leaves its host only temporarily. The young fish penetrates in the sea cucumbers by the head while the adult fish slip the end of their muzzle into the sac opening of the sea cucumber and contort themselves by movements of tail until engulfing itself entirely (Ref. 358). Also found on rubble (Ref. 111335). 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 (Ref. 833).
