🥚 Reproduction

Egg Diameter
0.85mm

Seems to spawn throughout the year in tropical and subtropical waters of the Pacific with peak spawning occurring in the respective local summer seasons. Spawning occurs with males and females swimming in pairs or with two or three males chasing a single female (probably a mating behavior). The ripe ovarian eggs are about 0.85 mm in diameter and have a single oil globule; there are no structures on the vitalize membrane and the egg is transparent. Eggs shed from captured female in the Indian Ocean averaged 1.304 mm in diameter.
