Common in shallow coastal bottom communities from the intertidal zone to depths more than 100 m. Forms aggregations, usually in the upper sublittoral zone (Ref. 635). May occur in three color variants: red type often found in offshore gravel beds while the green and black types often at inshore sandy-muddy bottoms (Ref. 77132). Juveniles often associated with algal/seagrass and oyster beds (Ref. 621). Most commercially important sea cucumber species (for trade, food and traditional medicine both; fisheries and farming/ranching) in China (Ref. 77133). Aquaculture now widespread in northern coast of China (Ref. 77133) since wild populations became over-exploited in the 1990s. Chinese aquaculture production peaked at 65,283 tons in 2005 (Ref. 77133). A sediment-feeder and bio-scavenger; ingests organic matter in sediment, e.g., bacteria, protozoa, diatoms, plant and animal debris including faeces (Ref. 77143).
Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
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.
