Leg span: 180 mm. Trunk: smooth with conical dorsomedian tubercles on segment posteriors, separated from lateral processes with smaller conical tubercles on dorsodistal tips. No appendage setae or spines. Neck: long, ocular tubercle as tall as trunk tubercles, positioned dorsally to oviger bases at posterior third of neck length. Eyes: small, indistinct. Proboscis: tripartite shape with proximal and distal rings. Abdomen: long, downward ventrally to plane of trunk. Chelifore: scapes 2 segments short, subequal in length, chelae vestigial, tiny knobs with minute segmentation line. Palps and ovigers: typical. Male oviger sixth segment with long and short setae subsequent to strigilis which has 3 to 5 rows of narrow denticulate spines. Terminal claw: short, small. Legs: long and slender, without spines or setae. Femur: long segment, tarsus shorter than propodus, claws short, claws of first leg pair small, no longer than wide. Cement glands: extend from proximal femore to distal first tibiae (Ref. 9).
Giant species.
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.
