Massachusetts Audubon Society volunteers recovered about 120 “cold-stunned” sea turtles during the weekend after strong winds caused them to wash up on the shores of Cape Cod Bay.

The majority of the reptiles found on the beaches of Wellfleet, Truro, Eastham, and Brewster were Kemp’s ridley sea turtles, a critically endangered species and the rarest type of sea turtle.

It was an unusually large late-season stranding for the turtles, who most often get stuck on Cape Cod shores around Thanksgiving as they try to make their way south to warmer waters for the winter.

Young sea turtles often feed in Cape Cod Bay during the summer but can get trapped in the “hook” of the Cape and become hypothermic as temperatures drop, according to Mass Audubon.

Despite their rarity, Kemp’s ridleys are the type of turtle most often found stranded on Massachusetts beaches.
