Last November, nine sea turtles were found stranded on a beach in Brewster, Massachusetts. They were cold and sick from icy temperatures.
The turtles were taken to the New England Aquarium. Then, they flew to the Georgia Sea Turtle Center in Jekyll Island, Georgia. There, they received food, water, and medical care.
The staff named the turtles after different types of tea. These included Chai, Boba, and Matcha. But one turtle, Earl Grey, looked very unusual.

The staff decided to run a genetic test on Earl Grey.
The results surprised everyone. Earl Grey is a first-generation hybrid. His father was a loggerhead, and his mother was a Kemp’s ridley.
Hybrid sea turtles are rare in the wild. Earl Grey is especially unique because he is half Kemp’s ridley. This is the smallest and most endangered sea turtle species in the world.
The Georgia Sea Turtle Center noted that this doesn't happen often. More research is being done on the turtle population.
Earl Grey’s story quickly became popular.
Learning from Hybrids
Jaynie L. Gaskin, director of the Georgia Sea Turtle Center, spoke with Popular Science. She said hybrid sea turtles like Earl Grey bring up many questions.
Gaskin explained that there is much to learn from these hybrid individuals. Scientists want to know how these turtles behave and grow. They also wonder where they nest, what they eat, and where they move during different life stages.
Each confirmed hybrid case helps scientists understand how these animals adapt in the wild. This also helps conservation strategies change with them.
Gaskin believes hybridization is mostly good for animals.
She said that from an evolutionary view, hybridization could add genetic diversity to a population. Gaskin encourages other rehabilitation centers to test any suspected hybrid sea turtles. There might be more of them than we realize.
