Um tubarão-martelo fêmea capturado em Florida Bay, teve filhotes sem copular com machos. De acordo com os cientistas, foram usados testes genéticos para a comprovação do aparecimento misterioso do filhote no tanque da fêmea.

A hammerhead shark captured in Florida Bay gave birth without sex, according to scientists who said they used genetic analysis to account for the mysterious appearance of a pup in a tank of female sharks.
The research was to be published today in the British journal Biology Letters.
