Aquarium staffers have treated 257 live sea turtles in all, which included 214 critically endangered Kemp’s ridley turtles; 39 green turtles; and four loggerheads. About 100 of those turtles have been rescued in just the last two days, according to a report from the aquarium.

The turtles washed ashore along Cape Cod Bay. They are being treated until they’re ready to be released back into the ocean.

After a rash of stranded turtles on Massachusetts shores in the last week, the New England Aquarium is now treating over 200 cold-stunned sea turtles in critical condition.
