Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Males usually have more setae, increasing in numbers distally. The abdomen sometimes lacks strong spines near its tip (broken off ?), and the strong spines at midfemur length are sometimes small or even absent. The tibiae sometimes have rather dense lateral and dorsal setae but some specimens have far fewer setae on these segments (Ref. 9).
North and South Islands from littoral depths to 400 m (Ref. 9).
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.
