Short description Morfologi

A slender, attenuated species. Lateral processes separated proximally by less than twice their diameters. Ocular tubercle a broad cone as tall as wide, situated at anterior of cephalic segment. Anterior eye pair much larger than posterior pair. Proboscis slender, only about as long as cephalic segment. Abdomen slender, not longer than posterior lateral process pair. Chelifore scapes equal in length to proboscis, chelae slender, fingers almost equal in length to palm, armed with 18 to 23 small teeth. Palp third segment longest, fourth longer than fifth. Legs very slender, second tibiae very long, first tibiae longer than femora. Propodus only slightly longer than tarsus (Ref. 2153, p. 19).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | 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.
