Several endangered species of sea turtles migrate to the waters of Cape Cod to feed over the summer. But once temperatures drop in the fall, their way out is perilous.
Before travelling south, sea turtles have to swim north and around the Cape into rapidly cooling waters. The resulting hypothermia causes a turtle’s muscles and other organs to shut down. The lucky ones wash ashore where they’re rescued by beach-combing volunteers.
Turtles needing intensive treatment are taken to nearby stranding centers. Those in better shape are transported to other rehabilitation facilities until they’re ready for release in warmer waters.
Similar events happen in waters off New York, North Carolina, Florida and Texas. Thanks to the efforts of rescuers, veterinarians and rehabilitators alike, most treated sea turtles return to the wild.
