Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm ?  range ? - ? cm
Proboscis moderately narrow, expanding proximally to midpoint, with slight taper distal to midpoint, about 1.8 times length of trunk, with moderate distal downcurve in lateral view. Trunk typical, lateral processes slightly longer than their diameters. Ocular tubercle a truncate cone, anterior pair of eyes twice larger than posterior pair. Abdomen carried horizontally, moderately long, extending beyond distal rim of first coxae of 4th leg pair. Palp segment 3 about 1.3 times length of segment 5, distal 5 segments subequal in length, with ventral fields of tiny spines. Legs slender, tarsus short, only about 0.4 times as long as slightly curved propodus. Both tarsus and propodus with very short sole spines and scattered lateral and dorsal setae. Terminal claw about 0.3 times length of propodus (Ref. 2153, p. 26).
Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
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.
