Trunk tubercles: tall slender and similar tubercles on the first coxae and to a lesser extent on the dorsodistal tip of the femora. Lateral processes: without tubercles. Ocular tubercle: short, carried almost horizontally, eyes at tip, prominent. Proboscis: quite short, recurved back ventrally under cephalic segment. Abdomen: very short, not extending to distal rim of second coxae, fourth leg pair. Palps: very short, terminal segment mounted laterally at base of shorter third segment forming subchelate, structure. Oviger: fourth segment longest, with constrictions suggesting additional segments beyond fourth are coalesced, armed with few distal spines. Legs: moderately short, first coxae with tall slender dorsodistal tubercle equal to but more slender than median trunk tubercles. Femora: with slender dorsodistal tubercle shorter than those of sole setae. Propodus: well curved, longer than short second tibiae, with row of short sole spines, claw short, robust, auxiliaries lacking (Ref. 9).
Associated with a hydroid (Ref. 121217).
Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | 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.
