The Florida Keys have been closed to visitors for a month due to the new coronavirus pandemic, but staff at the Turtle Hospital, a popular Keys environmental attraction, continue efforts to rehabilitate injured sea turtles.

Wearing protective facemasks, hospital staff released a rehabilitated green sea turtle back to the ocean Wednesday.

Aldo Leopold, a 100-pound juvenile green sea turtle, was rescued in late February after being discovered floating offshore, unable to dive. The endangered reptile was treated at the Turtle Hospital with broad-spectrum antibiotics, fluids, vitamins and a nourishing diet of fish, squid and greens.

Rescuers named Aldo Leopold after a renowned environmentalist of the early 1900s, sometimes referred to as the father of wildlife ecology and the United States’ wilderness system.

“The coronavirus has the Florida Keys shut down, but we’re still here taking care of over 40 sea turtles at the hospital,” Turtle Hospital general manager Bette Zirkelbach said.

The Turtle Hospital has been rescuing, rehabilitating and returning turtles to the wild for nearly 35 years. It even features four “turtle ambulances.”
