🥚 Reproduction

🐣 Ovoviviparous 🤰 Viviparous
Size at Maturity
4.8cm TL

Ovoviviparous. Sexes can be readily distinguished by the male's intromittent organ and the female's genital pore . On the basis of this morphology, copulation may involve flexion of the male's body and pumping of sperm into the female . Embryos are retained in the ovaries until about 6 mm long, deriving nourishment from large yolk sacs, making the species ovoviviparous rather than viviparous .

🌍 Habitat & Distribution

Marine; reef-associated; depth range 1 - 30 m . Tropical; 30°N - 28°S Indian Ocean: although reported to occur widely in the Indo-Pacific, specimens have only been collected at the Batu Islands, off Sumatra, Indonesia.
