Skerry saw this large adult female leatherback turtle in Trinidad at about 1 or 2 a.m. using the moon as his light source. A flash was out of the question—the white light disturbs the nesting patterns of the turtles.
“Leatherbacks are the oldest, deepest-diving and widest-ranging of all sea turtle species,” Skerry says. “Their lineage dates back more then 100 million years—they’re older than dinosaurs, yet today they are also endangered.”
