Biography
The diamondback terrapin is a vital component of its coastal ecosystem. With its striking diamond-patterned shell and ability to thrive in both salt and freshwater environments, the diamondback terrapin is a true marvel of adaptation. Specialized salt glands located near their eyes enable them to efficiently eliminate excess salt from their bodies, allowing them to adapt to the fluctuating salinity levels of their primary brackish water habitat. Additionally, their skin is largely impermeable to salt, which further aids in their estuarine adaptations. They can also distinguish between drinking water of different salinities. Their large webbed feet and muscular legs make them strong swimmers. During the nesting season, female terrapins venture onto land to lay their eggs in sandy nests, often near the water's edge. A typical clutch can contain 4 to 20 eggs, which the female buries and leaves to incubate in the warm sand. After about 60 to 90 days, the hatchlings emerge and make their perilous journey to the water, where they face numerous predators, including birds and large fish. The young terrapins are vulnerable, but quickly learn to navigate their environment, often seeking refuge in the safety of coastal crevices and marsh grasses. Historically, diamondback terrapins faced significant threats from overharvesting for their meat and shells, as well as habitat loss due to coastal development and pollution. These pressures led to a decline in their populations, prompting conservation efforts to protect their habitats and promote sustainable practices. They are still at risk due to collisions with boats and cars and drowning in unattended crab traps. While some populations are recovering, the diamondback terrapin remains a species of concern, highlighting the need for continued awareness and protection.
Our Animal's Story
Our diamondback terrapin is a female and is named Ria. She arrived at ZooAmerica in 2022. Her estimated hatch date is August of 2016. Females, like Ria, can reach a carapace length of 9 inches, while the males usually reach a maximum of about five inches.
