Description of life cycle and mating behavior | Ovoviviparous. During the mating season, mature males and females have been observed to change hue, i.e., become brighter, when courting (Refs. 52034, 89259). Female deposits her eggs on the brood pouch of the male which is found under the tail (Ref. 205). Gestation usually lasts 21 days (Ref. 89322) and brood sizes up to 581 have been reported (Refs. 53712, 79902, 89322). Young are expelled from the pouch measuring 1.5 cm after 3 weeks of incubation. Size at birth ranges from 0.6-1.4 cm length (Ref. 79902). Newly hatched young are planktonic for at least 8 weeks (Ref. 53712). |
