Species extremely variable, particularly in appendage length ratios. Chela palm is much longer fingers, tarsus length equals propodus (or is sometimes shorter), ocular tubercle is taller, third palp segment much longer and fifth segment longer than fourth, and major leg segments are measurably longer than in Nymphon brevitarse.
Variation occurs in terminal leg segment length ratios. Tarsus can be slightly shorter than propodus or twice as long as propodus or longer, and sole spines vary in number and length (Ref. 2153, p. 21).
Shelf (Ref. 19). Found at depths of 4 to 1656 m (Ref. 119523).
Life cycle and mating behavior Maturity | Reproduction | Spawning | 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.
