Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Proboscis inflated at both midpoint and distal end. Species has two or three major heel spines larger than sole spines but not nearly as large as heel spines of Pallenopsis californica. Abdomen very long; tibiae with rows of long, slender, lateral setae, and cement gland tube nearly as long as femoral diameter. Chelae conspicuously smaller relative to those of other species (Ref. 2157, p. 4).
Abyssal (Ref. 19).
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.
