Sea turtles are anything but lazy. It's hard work for them just to survive. For more than 100 million years, sea turtles have returned en masse to the same beaches where they were born to lay their own eggs. While this age-old method has helped sea turtles survive so long, their predictability leaves their eggs open for poachers. Only one in 1,000 sea turtle hatchlings reaches adulthood, and the black market for turtle eggs is a big reason for these dire numbers.
