【 摘 要 】

Elasmobranchs present four clasper movements, which can be seen in different contexts from mating to no obvious reason.  Three movements have been reported in Carcharias taurus and here the first occurrence of clasper flaring in this species is described.  Clasper flaring was observed while other species were in a reproductive state and their aggressive behaviour towards the subject of this study was also observed.
