Trunk and proboscis large but size only intermediate with leg span of about 25 cm. Ocular tubercle quite low with small eyes. Proboscis broadly expanded from narrow base, sown curved, longer than trunk. Palp longer than proboscis, distal 3 segments subequal in length. Oviger terminal claw opposed by subchelate larger spine forming pincer-like claws. The propodus is only 0.6 as long as the tarsus and the terminal claw is short (Ref. 9).
Continental rise (Ref. 1456); continental shelf, continental slope (Ref. 1456 and 19).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | 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.
