Still one tie to land
Green turtles can migrate thousands of miles from foraging grounds to nesting beaches. Following chemical cues, a female returns to the same beach where she hatched. She lays about 100 ping-pong ball-sized eggs in a deep nest, covers them and leaves. Hatchlings instinctively head for the sea. While females come ashore to nest every two to three years, the males never return to land. The loss of nesting beaches due to coastal development and rising sea levels is a threat to all seven species of sea turtles.
A conservation ambassador
Nickel, Shedd's rescued green sea turtle, has been the star of the Caribbean Reef habitat since 2003. She came to Shedd after surviving a boat collision that left a deep gash in her shell and affected her buoyancy—but not her ability to navigate her habitat with ease and learn behaviors that help us care for her. Nickel helps raise awareness about the many threats to her species, including the increasing problem of plastic marine debris, which sea turtles can mistake for food or become entangled in.

Decades Later, Scientist Reunites with Sea Turtle He Saved

A Weighty Anniversary for Nickel
On Nickel’s first day in the 90,000-gallon Caribbean Reef habitat on July 22, 2003, she took to her new home as if she’d always lived there.
