Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
The male holotype has a fully ripe testis and the female paratype with a great number of eggs in several developmental stages. The most developed eggs were ca. 0.4 mm in diameter, round with a single oil globule (Ref. 93890).
