Thoughtful Thursdays: Endangered Species Spotlight on Kemp's Ridley Sea Turtles
Published May 16, 2013
Endangered Species Day, celebrated on May 17th, was established to raise awareness of the issues (both human-related and ecological) facing endangered species and their habitats.
To help further amplify this day, we’ll be highlighting some endangered species that can be found in our home state of Maryland, at the National Aquarium and around the world! Our hope is that as this week progresses, others will feel inspired to help us protect these amazing animals!
Kemp’s ridley Lepidochelys kempii sea turtles are the smallest of all the sea turtle species and are listed as "critically endangered" by the IUCN. “Small” is a relative term for sea turtles, as the Kemp’s can weigh as much as 80 to 100 pounds as adults, and their shell can grow to about 2 feet long. Their carapace (top shell) is usually heart-shaped and brown to grey in color.

Kemp’s ridley’s are highly migratory and seasonal visitors to Maryland waters. They can often be found in coastal areas, including the Chesapeake Bay and Atlantic coast, from late May to October. While here, they feed on an assortment of crabs, shellfish and jellies, and will occasionally munch on seaweed. Cooler water temperatures in the fall signal the turtles to migrate south – reptiles are ectothermic, meaning their internal body temperature is dependent on the water temperature.

Along the northeast and mid-Atlantic in late fall and early winter, Kemp’s can become victims of cold-stunning. Cold-stunning is effectively hypothermia (low body temperature), which causes the turtles to stop eating and ultimately become severely sick. The 2012 cold-stun season was a record for the northeast. We currently have two Kemp’s ridley sea turtles in rehabilitation with our National Aquarium Animal Rescue team, and both were admitted as cold-stuns.
Since being listed as an Endangered Species in 1994, the US and Mexico have worked cooperatively to protect critical nesting habitats for the Kemp’s, resulting in an increase in successful nesting and hatching. Kemp’s still face many threats, though, many of which are human-related. The good news is that YOU can help protect Kemp’s ridley sea turtle populations!
Stay tuned for more features on endangered species this week!
