Short description Morphology

Trunk and appendage integument lightly reticulated or sometimes unreticulated but granular. Trunk with slender dorsomedian tubercles, rounded or pointed. Lateral processes slightly longer than diameter, closely spaced but separated distally, with low dorsodistal bulges sometimes becoming a continuous dorsal ridge. Proboscis a long tapering truncate cone with flat oral surface. Abdomen fairly long, slender, tapering distally, extending beyond distal rim of first coxae, fourth legs. Oviger 9 segmented, of moderate size, terminal claw slightly curved. Legs with moderately slender major segments, with very few short spines. Propodus tapers distally to smaller diameter, sole with pile of short spines, claw robust, long, more than half length of propodus, auxiliary claws lacking (Ref. 2153, p. 16).

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.
