Trunk with 3 sharply pointed median tubercles bearing lateral setae; lateral processes with similar dorsodistal tubercles; lateral processes and legs variously setose, with many or few setae per segment. Neck moderately short; ocular tubercle slightly taller than its basal diameter, placed medially, with bulbous swelling just posterior on neck. Neck sometimes with lateral setae. Proboscis broadly oval, with proximal constriction only. Abdomen long, extending just posterior to distal rim of first coxae of fourth legs. Chelifore scapes 1 segmented, very short, sometimes bent ventrally. Oviger typical. Legs short, setose; femoral cement gland(s) not evident. Claw moderately short, of equal length on all legs (Ref. 2115, p. 21).
From Intertidal depths, some subtidally (Ref. 2115, page 21). Epibiotic (Ref. 116112).
Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
