Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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.
