One of the largest species of the genus, many specimens known with leg spans more than 50 cm. Proboscis long, very swollen medially, with smaller swelling distally, without curve of any form. Palp much longer than proboscis, fifth segment almost as long as third, seventh only slightly shorter, distal three segments subequal in length. Legs conspicuously long and slender. Tarsus about 0.4 longer than propodus, claw about half propodal length (Ref. 9). Largest species of genus known in Arctic.
Legs extremely long, leg span up to 70 cm. Proboscis about 1.5 times longer than trunk, medially inflated; narrowing proximally and distally, with slightly swollen oral surface, not conspicuously curved. Distal palp 3 segments subequal in length. Tarsus about 1.5 times longer than propodus, claw slightly less than half propodal length (Ref. 2153, p. 24).
Minimum depth from Ref. 117242.
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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.
