Abstract

Negaprion brevirostris and Ginglymostoma cirratum are large coastal sharks with a wide geographic distribution in the tropical western Atlantic Ocean whose southern populations are listed as vulnerable. Herein is reported the use of Fernando de Noronha Archipelago as a nursery habitat by both species in the equatorial Atlantic. Parturition time in N. brevirostris takes place between November and April whereas in G. cirratum it occurs from July to September.
