Biologie     Verklarende woordenlijst (b.v. epibenthic)

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes (Ref. 103751). Juvenile hermaphroditism is exhibited by this species (Ref. 35994).
