"More Sea Turtles Come To Florida, But Reasons Are Mysterious"

"This year's early count of sea turtles nesting on Florida beaches is encouraging, though there are many unknowns in the numbers.

Welcome to the mysterious world of sea turtles, which spend much of their life far from Florida's beaches encountering fishing boats, oil spills, plastic trash and any number of other perils.

Nesting by loggerhead, green and leatherback turtles has been trending up in numbers for nearly the past five years along the state's coast. But there have been significant dips and climbs in their nest counts."
