Size large, male leg span about 8 cm (female about 13 to 15 cm). Trunk fully segmented, narrow, glabrous, lateral processes about 1.5 times longer than diameters, with few short dorsodistal setae. Neck wider than trunk, oviger bases against first lateral processes, conspicuous palp buds extending laterally. Ocular tubercle a curved cone with large eyes. Proboscis a moderately long cylinder, lips tapered. Abdomen medium length, upcurve, with tiny setae (Ref. 9). Chelifore scapes as long as proboscis, with few scattered setae. Chelae palms slender, twice as long as wide, with fringe of distal and endal setae. Fingers narrow, movable finger with setose proximal pad, longer than immovable finger. Oviger second segment almost twice length of third or first, fifth only little longer than sixth. Strigilis segments with many short setae, none longer than segment diameters except for those of smaller terminal segment. Legs moderately long, with dorsal and ventral fringe of short setae. Tibia 2 the longest segment. Ventral cement-gland tube of varying length, from 0.2 to 0.7 of femoral diameter. Tarsus very short, with one large ventral spine and several setae. Propodus with three major heel spines, several short sole spines with setae, and claw about half propodal length. Auxiliaries 0.5 - 0.7 length of main claw (Ref. 9).
Life cycle and mating behavior
পরিপক্কতা | প্রজনন | ডিম ছাড়া | ডিমসমূহ | ডিম্বধারন ক্ষমতা | শুককীট
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.
