Short description Morphology

Size intermediate among species. Proboscis longer than trunk, robust, conspicuously down curved over its entire length (rather than only distally). Palp segments moderately short, fifth less than half length of third, seventh next-longest, followed by eighth, tenth, sixth, and ninth which is shortest (other than two very short basal segments). Palp distal two segments recurved posteriorly toward trunk. Oviger terminal claw only as long as terminal segment diameter. Leg distal segments quite short in relation to long legs. Tarsus slightly shorter than propodus, claw less than propodal length (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.
