  • Our smallest sea turtle.
  • A heart-shaped carapace (top shell) which is smooth and olive green, grey or black, with serrations along the rear margin.
  • Head and flippers are grey or olive.
  • The plastron (bottom shell) is white.
  • Five costal scutes on each side of the carapace.
  • The first costal scute touches the nuchal scute. Bridge scutes have pores.


Marine waters of the Chesapeake Bay, coastal bays, near shore and the continental shelf (< 150 feet deep). Often associated with eelgrass meadows. No nesting occurs at our latitude (most nesting is at Tamaulipas, Mexico). Most of our turtles are juveniles. During the summer months, the lower Chesapeake Bay has the highest concentrations of juvenile Ridleys in the world.

How to Find:

Juveniles may be observed in the Chesapeake and coastal bays in shoal areas with eelgrass beds close to shore, feeding on blue crabs. They can also be found loafing/basking for long periods on the surface, however they maintain a low profile with the carapace mostly submerged. Look for them from May to November. State and federally listed as Endangered. If you find or observe any individuals, please contact DNR’s Wildlife and Heritage Service. ​
