Now males have been observed to prod the female's genital opening prior to copulating with her, and in what I have lovingly termed the Magnum, P.I. hypothesis, females are overwhelmingly more likely to be found with males that have these fish mustaches.
Agora, observou-se que os machos precisam estimular a abertura da vagina antes de copular com ela, e o que apelidei carinhosamente de hipótese Magnum P.I., as fêmeas são muito mais suscetíveis a machos com esses bigodes de peixe.
