A species that may travel thousands of miles across ocean basins, loggerheads are in grave danger due to worldwide habitat loss and incidental capture in fisheries.
In the North Atlantic Ocean, post-hatchlings and small juveniles swim with mats of Sargassum seaweed for years before returning to nearshore areas off the USA east coast as large immatures. It can take Loggerheads 20 to more than 30 years to reach sexual maturity.
