Species' maximum length from the Belgian part of the North Sea (Ref. 7882). Uncommon and in small numbers, found along the coastal zone in the North Sea off Belgium, in medium to coarse-grained sediment with very low mud content (Ref. 7882). Along the French coast of the southern North Sea, found in soft bottoms of muddy to heterogeneous sand and influenced by estuarine outflows (Ref. 96507).
Life cycle and mating behavior
половая зрелость | размножение | нерест | Eggs | Fecundity | Larvae
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.
