Biology     Glossary (e.g. epibenthic)

Found in shallow subtidal in protected, often densely vegetated areas (Ref. 125146). Also found in lagoons (Ref. 125074). Collected on the shore at a depth of 0 to 1 m, from under stones and algae (Ref. 125166). Main food and feeding type based on another species of the same genus; to be replaced with a better reference (Ref. 95732).

Life cycle and mating behavior Maturity | Reproduction | Spawning | 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.
