Biologie     Glossaire (ex. epibenthic)

A common inshore bottom shark (Ref. 247). Often found in estuaries (Ref. 4832). Probably feeds mainly on invertebrates (Ref. 247, 43278). Oviparous (Ref. 43278, 50449). Utilized as a food fish (Ref. 171).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Oviparous, deposits eggs in small, oval eggs cases on the bottom (Ref. 247). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). During copulation observed in captivity, the male bites the female's pectoral fin in a side-to-side position (Ref. 49562, 51121).
