Biologie     Glossaire (ex. épibenthique)

Minimum depth from Ref. 125127. It inhabits muddy areas, with low temperatures and medium high salinity at depths over 35 meters, compared to shallower areas (Ref. 95730). A mobile surface detritivore (Ref. 95752). Are nocturnal swimmers. Growth periods linked to spring phytoplankton blooms. Semelparous, with lifecycles lasting from 1 to 3 years in the northern Baltic proper. Eggs hatch in March-April. Sexual maturity is attained in 6 to 7 months (autumn). Males then undergo metamorphosis to adapt to pelagic life during which they do not feed, mate with females along the water column and then eventually die. The females, on the other hand, die after releasing their young the following spring (Ref. 90432).

Cycle de vie et comportement reproducteur Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Members of the order Amphipoda are gonochoric and sexually dimoprhic (males larger than females). Mating behavior: Males locate potential partners with the aid of their antenna to detect the pheromones released by the females; the male then rides or carries the female until the latter is ready to molt. When the female is ready, the male pushes the sperm into the marsupium and releases the female afterwards. A few hours later, the female releases her eggs into the marsupium for fertilization. Life cycle: Eggs are brooded in the marsupium. Eggs hatch into juveniles and remain in the marsupium for a few days. Each species undergo 20 molts at most, i.e., 1-year long life cycle.
