Environment: milieu / climate zone / depth range / distribution range
Ecology
Bathydemersal; depth range 100 - 1430 m (Ref. 2017). Polar
Northern Atlantic: Greenland (Ref. 12).
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Proboscis: Inserted in hydranth which held by chelifores (Ref. 214).
Bathyal (Ref. 19). Feeding on hosts: Hydroid Campanularia and Dynamena pumila (Ref. 12); observed feeding on Campanularia. 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 (Ref. 833).
