Description:
Under typical environmental conditions, the eggs of this organism usually hatch within a span ranging from a few days to several months. Upon hatching, the larva emerges as a shelled nauplius larva possessing three pairs of appendages representing antennules, antennae, and mandibles. Throughout its life cycle, eight moults occur, leading to eight additional instars, with the adult stage representing the ninth instar. With each moult, the organism develops more appendages and experiences increased structural complexity. For instance, the caudal rami initially manifest as two minute bristles during the fourth instar. Although the copulatory organ becomes apparent during the eighth instar, sexual maturity and copulation are achieved during the ninth and final instar. As for its physical description, the body of this organism is encased in a thin, transparent, bivalve shell. There is no prominent band of pore canals observed on the margins of the valves. The natatory setae extend up to the tip of the terminal claw of the antennae. One of the furcal rami is curved, with the broader ramus armed with teeth while the other is smooth. Teeth are also present on the claws, and the third leg features long reflexed setae. In terms of coloration, the organism appears whitish, with a body length of approximately 1.6 mm and a width of 0.76 mm.
