Turtles on Ascension Island
In Turtles on Ascension Island, narrator David Attenborough highlights the green sea turtles that travel incredible distances to lay their eggs on the beaches of Ascension Island. A female turtle may swim over 1,000 miles from her feeding grounds without eating for two months. At night, female turtles come ashore to nest, while eggs laid earlier in the season begin to hatch. Newly hatched turtles must quickly reach the ocean to avoid predators. However, their journey is just beginning — most will not survive the next 20 years. Yet, those that do will return to the same beach where they were born, guided by an instinct that scientists still do not fully understand. This video is excerpted from BBC’s Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
