Ecology: Deep shelf to upper slope (Ref. 19). Chelifore: fingers curved, with a wide gap between them (Ref. 12). Deep shelf to upper slope (Ref. 19). Probably associated with Umbellula encrinus. Peculiar shape of the species may be adapted to grasping Umbellula sp. tentacles (Ref. 121217).
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.
