Happy World Sea Turtle Day! Today marks the annual opportunity to highlight the importance of sea turtles and coincides with the birthday of Archie Carr, the namesake of our center, who is considered the father of sea turtle biology and conservation. Photo credit: University of Florida Archives

Archie Carr kneels next to the ocean's edge, waves behind him and several dozen sea turtle hatchlings in front of him.

New pub: This is a first look at whether sea turtles undergo age-related declines in the number of eggs they lay. Surprisingly, sea turtles can maintain their high reproductive output well into old age. However, the chances of dying do not follow a similar trend, with mortality increasing with age.

Ariadna Arnau successfully deployed three satellite transmitters on loggerheads at Wassaw Island, Georgia last week. Stay tuned for updates. We are particularly interested in their internesting habitat use and indicators of feeding status.

ACCSTR student Renato Saragoça Bruno found that green turtle diet in Nicaragua has not changed much since the last assessment in the 1980s. And curiously, nesting females in Tortuguero, Costa Rica consume terrestrial vegetation during the nesting season.
