🥚 Reproduction

🐣 Oviparous
Size at Maturity
26cm TL

Oviparous. Non-copulatory. However according to one study, presence of fertilized eggs in the ovary may have resulted from spermatozoa entering the ovary through the ovarian fluid during spawning, and consequently fertilizing unspawned eggs in the ovaries . Fertilized eggs in the ovary develop abnormally however, due to the unavailability of needed elements such as oxygen in the ovary .
