Short description Morfologi

Ocular tubercle low, with tiny apical cone. Proboscis ovoid, with distal constriction around mouth. Abdomen ovoid, extending almost to distal rim of first coxae of fourth leg pair, with 4 to 6 short distal setae. Chelifores with single short segment, about twice as long as wide, each with 3 distal setae; chelae absent. Palps 5 segmented (sometimes 6), extending slightly beyond proboscis; third segment longest. Ovigers 10-segmented, smaller in female; seventh segment of male without typical apophysis ("elbow") but with 3 or 4 long spines; terminal segment tiny, with 2 long, simple spines. Legs robust, with typical setose dorsal swellings; propodus large, with dorsal and lateral setae, 3 large heel spines, and auxiliary claws more than half length of robust main claw (Ref. 2115, p. 35).

Biologi     Ordlista (t.ex. epibenthic)

Minimum depth from Ref. 116112. Epibiotic (Ref. 116112). Common inhabitant of Sargassum (Ref. 2115, page 35). Feeds on a demosponge (Ref. 121217).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

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.
