Maturity: Lm ? range ? - ? cm
Its body length is 1.4 to 2.2 cm. Live specimens are mottled, brownish-black-white- patches in color on the first 6 pereonites, uniform dark-brown on the 7th, and uniform light brownish greenish coloration on pleon segments. It has large, kidney-shaped gold colored eyes.
Minimum depth from Ref. 87801. Found on sediments (e.g., muddy sand, coarse sand, shell, stones), polychaete (Chaetopterus) tubes, calcareous algae, dead algae (Ref. 74426), mussel and coral rubble (Ref. 87801). Scavenger (Refs. 74427, 87801).
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.
