Allarme dei ricercatori.
E’ allarme squali dopo i recenti episodi di sangue nelle spiagge di Acapulco. “Ormai vanno ormai a caccia di esseri umani”, dicono i ricercatori messicani.

Gli squali come i panda. Per favorirne l’accoppiamento, c’è chi prova con la musica. E a volte capita il miracolo …
How do you get two sharks to fall in love? Scientists at Blackpool’s Sea Life Center think that music is the answer. Bloodnose, a 20-year-old brown shark, has completely ignored Lucy, his 15-year-old companion, for the last year. The scientists have played Barry White love songs to the sharks, but Bloodnose still isn’t in the mood for love.
Supervisor Carey Duckhouse says, “We’re playing them the kind of soft romantic music that inspires powerful emotions in humans”.
Duckhouse continues, “Honestly, we’re not crazy! US studies demonstrate sharks really react to music with similar emotions”. The scientists are now planning to serenade the sharks with classical greats such as Mozart’s Romanze and Puccini’s Nessun Dorma.
Duckhouse says, “Hopefully, by next year, we will have six or seven little shark pups to look after”.
Like a Virgin
Perhaps the Blackpool scientists are wasting their time: a hammerhead shark at the Henry Doorly Zoo in Omaha, Nebraska, gave birth without the help of a male shark, through parthenogenesis, or “virgin birth”.
This is possible in all vertebrates, except mammals and, until now, sharks. The discovery has important implications for the many species that are in danger of extinction, though scientists warn that parthenogenesis weakens a specie’s genetic make-up.
