Könsmognad: Lm ?  range ? - ? cm Max length : 1.6 cm TRKL hane/ej könsbestämd; (Ref. 9)
Proboscis is consistently from 1.2 to 1.6 cm trunk length and always has a slight distal down curve. It is swollen both at midpoint and distally. Palp is considerably longer than the proboscis, the seventh segment of which is half as long as the distal two segments which are subequal. Tarsus is always longer than the propodus and the terminal claw is also long (Ref. 9).
Abyssal, continental rise, continental shelf (Ref. 1456); continental slope (Ref. 1456 and 19). Feeds exclusively on hydroids (Ref. 121217).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | 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.
