Question

   Can you name an animal that returns to the place of its birth,every single year,journeying more than 1,000 km to do so? Well,here is another hint： this animal is a sea creature that originated on earth more than 200 million years ago一making the species older than the oldest ever dinosaur.

   Sea turtles live mostly in warm waters around the world and are graceful swimmers. Each year,from December to April,Gahirmatha plays host to hundreds of thousands of female Olive Ridley turtles. These turtles lay their eggs on the same beach where they were born. Turtles always return to the same nesting site year after year,even if they migrate (迁徙) thousands of kilometers. This particular phenomenon (现象) has baffled (困扰) scientists for years now and no one has any clue as to why they do so.
