Minimum depth from Ref. 87027. Only herbivorous amphipod known to feed only on and creates a domicile out of a few closely related seaweeds which produce dictyol-class diterpenes, a compund that prevents it from being eaten by reef fishes (Ref. 86733). Inhabits a portable domicile that is constructed from a rare alga, Dictyota bartayresii (Ref. 86733).
Life cycle and mating behavior
Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Eggs | Sự sinh sản | 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.
