This species is superficially like Nymphon maoriana Clark. It has shorter chelifores with smaller-sized teeth, an ocular tubercle taller than wide, legs with conspicuous sharp distal spines, and a tarsus only half as long as the short propodus. The similarities reside in the plain trunk, short neck, very short palp segments and short legs with long claws.
Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | 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.
