On May 30, 2004, the Aquarium provided a satellite tag for the monitoring of a leatherback sea turtle that nested on Gandoca, a remote beach in Costa Rica.
The map below is updated weekly to provide a record of the turtle's movements.
Mounted by the Caribbean Conservation Corporation in conjunction with Costa Rican conservation group ANAI, the tag allows scientists to monitor the movements of this critically endangered animal, named Purruja.
“Sea turtles constantly migrate to different waters in search of new places to feed and mate, returning to the same beaches year after year to nest,” said David Schofield, the Aquarium’s manager of ocean health initiatives.
“The satellite tag shows us exactly where these animals go, and supports our goal of producing stronger regional and international efforts to protect this endangered species,” he said.
ANAI volunteers have monitored the beaches of Gandoca, Costa Rica, since the 1990's, watching for nesting sea turtles. Purruja has nested twice this year on Gandoca’s beaches.
Through this satellite monitoring, scientists have learned that she also nested in Panama, out of ANAI’s volunteers’ sight.
A Species on the Edge
Once numerous, all sea turtle species are now sliding toward extinction. The Caribbean adult leatherback population currently hovers only around 25,000 individuals, approximately 1% of the 1980 population.
Leatherback sea turtles are the world’s largest sea turtles, reaching eight feet long and weighing as much as a small car. They are hunted for their meat, shells, and eggs.
“We watch between 400 and 500 turtles, like Purruja, lay eggs each year. After the mothers return to sea, we help ensure the clutches’ safety,” said Didiher Chacón, ANAI’s director of the sea turtle conservation project.
“Their population has dropped to the point that each individual counts," he continued. "Our goal is to help the next generation of leatherbacks thrive.”
Turtle Rescues
The Aquarium’s Marine Animal Rescue Program has responded to six calls about leatherback sea turtles in Maryland waters over the past 12 years.
Three of the turtles were disentangled from fishing gear and healthy enough to swim away. Sadly, the others perished.
While this is the first time that the Aquarium and ANAI have collaborated on sea turtle conservation, the Aquarium has collected more than $380,000 in donations from visitors, which ANAI then uses to purchase rain forest land, protecting it from development.
