Maturity: Lm ? range ? - ? cm Max length : 1.5 cm LS male/unsexed; (Ref. 170)
More slender and graceful than usual appearance of closely crowded appendages in most species of genus. Lateral processes increasingly shorter from anterior to posterior but its short conical ocular tubercle and abdomen are typical of genus. First coxae with short conical tubercle on posterodorsal side at distal rim of segment. Auxiliary claws dorsal to main claw; cement gland orifice at cribriform slit proximal to midline of each femur.
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Pycnogonida are gonochoric and sexually dimorphic. During copulation, male usually suspends itself beneath the female. Fertilization occurs as the eggs leave the female's ovigers. Males brood the egg masses until they hatch. Life cycle: Eggs hatch into protonymphon larva then to adults.
