The Coast Guard flew more than two dozen sea turtles to Orlando on Friday.
Reports say the 20 turtles were taken to SeaWorld, Orlando.
Five loggerhead turtles were taken to the Volusia County Marine Science Center.
Three other facilities in Florida also took in turtles.
A New England Aquarium spokesman says a record number of endangered and federally protected sea turtles have been treated this year for cold stress.
SeaWorld officials say an unseasonably warm November delayed the turtles' exit from Cape Cod Bay.
When water temperatures suddenly dropped, the turtles developed hypothermia and washed ashore.
The turtles will be returned to their natural habitat when water temperatures are warmer.
