Biological Profile & Identification
The Kemp’s Ridley (Lepidochelys kempii) is the world’s most endangered and geographically restricted sea turtle species. Inhabiting primarily the Gulf of Mexico and the Atlantic coast of North America, Kemp’s Ridleys are unique among sea turtles for nesting almost exclusively in broad daylight.
Key Anatomical Characteristics
- Nearly Circular Carapace: Wide, round, grey-green carapace that is almost as wide as it is long.
- Five Pairs of Costal Scutes: Distinctive triangular head with powerful jaws specialized in crushing Atlantic blue crabs (Callinectes sapidus).
- Size: Along with the Olive Ridley, the smallest of all seven sea turtle species.
Top Geographic Zones for Kemp’s Ridley
- Rancho Nuevo (Tamaulipas, Mexico) — The sole primary nesting beach in the world for this species.
- Padre Island National Seashore (Texas, USA) — Nesting re-establishment sanctuary and hatchling releases.
- Cedar Key & Florida Gulf Coast (USA) — Coastal feeding grounds for foraging juveniles.
