We’re excited to share that we recently released 13 diamondback terrapins back into a coastal estuary in Southeast Louisiana! 🐢 🌊
These turtles were part of our first-ever hatchling group from Audubon Aquarium and participated in a “head start” conservation program in partnership with Nicholls State University and Barataria-Terrebonne National Estuary Program. This program raises young terrapins in controlled, optimal conditions until they reach a larger size, giving them a better chance of survival once released into the wild.
For these terrapins, we raised them in freshwater until they reached about 7.5 inches, then transferred them to Nicholls State University to acclimate to saltwater before release. This extra head start helps them survive their most vulnerable early life stages and improves their chances of reaching adulthood.
Diamondback terrapins are a keystone species in coastal marshes. By helping control periwinkle snail populations, they protect marsh grasses - critical plants that stabilize wetlands and help reduce coastal erosion. Without this balance, our marsh ecosystems could suffer significant decline.
This release wouldn’t have been possible without the dedication of our Husbandry team and Learning & Engagement team, whose work with care, measurements, and preparation helped make this project a success!
