Observations on six elasmobranch species recorded from off the coast of Senegal (eastern tropical Atlantic)

Abstract

       The authors report biological observations about six elasmobranchs species caught off the coast of Senegal and landed at craft fishery sites in the Cape Verde Peninsula (Eastern tropical Atlantic). These species are Etmopterus spinax, Oxynotus centrina, Rhincodon typus, Scyliorhinus cervigoni, Torpedo bauchotae and T. marmorata. They are rather rare in the area. Nevertheless, new data allow suggesting that hydrobiological parameters do not play an important role in the reproductive biology of the viviparous species.
