3 Types of Sea Turtles in Massachusetts

1. What species of sea turtles are found in Massachusetts?

Five sea turtle species have been documented in Massachusetts waters: Kemp's ridley, loggerhead, leatherback, green, and hawksbill. Of these, Kemp's ridley, loggerhead, and leatherback are the ones you are most likely to see. Green turtles appear occasionally, and hawksbills are extremely rare. The cold waters of the North Atlantic act as a seasonal feeding ground, especially during summer and early fall.

2. How can you tell Kemp's ridley from loggerhead sea turtles?

Kemp's ridley is the smallest sea turtle, with an adult shell length of about 2 feet. Its shell is nearly round and olive gray. Loggerheads are larger, with a more heart-shaped shell and a noticeably large head. Their shell is reddish brown. A quick way to separate them: Kemp's ridley has a smaller, rounder body and a beak that curves downward.

3. Where and when are leatherback sea turtles seen off Massachusetts?

Leatherbacks are the largest sea turtles and the most likely to be seen far offshore. They have a unique leathery shell without scutes. Best time to spot them is from June to September in the waters of Cape Cod Bay and south of Martha's Vineyard. They follow jellyfish blooms, so look for them near the surface on calm days.

4. What about green sea turtles and hawksbills?

Green turtles are occasional visitors, usually as juveniles in warmer months. Their shell is smooth and olive to brown, with a serrated edge. Hawksbill turtles are extremely rare in Massachusetts; if seen, it is likely a lost individual. Hawksbills have overlapping scutes that form a distinct pattern. Their narrow, bird-like beak sets them apart.

5. What is the best way to identify a sea turtle species in the wild?

Start with size and shell shape. Leatherbacks are huge (up to 6 feet) and have a black, leathery back. Kemp's ridley is small and round. Loggerhead has a large head and reddish shell. Green turtles are medium with smooth shells. Also note the swimming pattern: leatherbacks move with deep, slow flipper strokes; smaller turtles are quicker. Always keep a safe distance and use binoculars.

6. Where should you go to increase your chances of seeing sea turtles?

Cape Cod Bay, especially around Wellfleet and Truro, is a hot spot for stranded or feeding turtles. The waters off Chatham and Monomoy Island are good for loggerheads. For leatherbacks, head to the continental shelf edge south of Nantucket. Summer boat tours from Provincetown sometimes encounter turtles.
