The Eizaguirre Lab


A public Data Base of the sea turtles of Cabo Verde

TurtleBase is one of the longest datasets of sea turtles in the Atlantic made available to other research and conservation groups via an online platform.

TurtleBase is the result of The Turtle Project, a large citizen-science project designed to improve the conservation of the endangered loggerhead turtles of Cabo Verde. This database contains information from over 5,000 loggerhead turtles that nested in the archipelago of Cabo Verde, including id tags, haplotypes and stable isotopes.

The data has been collected since 2008 by researchers from The Eizaguirre Lab with the help of students, volunteers and local conservationist from NGOs in 10 different islands of the archipelago.
