英语听力：自然百科 鲨鱼湾的海豚—8（在线收听） |
Oh,whistle,i thought i hear a whistle here.something extraordinary is happening.Puck uses her unique call to identify herself to other dolphins,Yet strangely there are no other dolphins around.J believes that Puck is calling her unborn calf,if she is right,it is a astonishing discovery.she is basically advertising the calf,i am you mum,hear me,hear me.And hopefully the baby then where to go after it's born. Puck only calls to her unborn calf when she is alone.
J suspects this happens in the week before the calf is born.she thinks the birth is imminent.
It's a shark,it is really a big one i don't know,three meters.?may be.Tiger sharks members are staring to build up.soon thousands of more tiger sharks will arrive in the bay.having already lost one calf to sharks,this is the worst possible timing for Puck.More than 75 percent of the dolphins bear the scars of their attacks.
