Migratory Routes
Migration habits differ not only among species
but also among different populations of the same
species. Some sea turtle populations nest and
feed in the same general areas others migrate
great distances. Loggerheads leave foraging areas
and travel on breeding migrations that range from
a few to thousands of kilometres (1 kilometre
0.62 miles).
Endangered Species
The loggerhead turtle was listed as threatened
throughout its range on July 28, 1978 and its
status has not changed Loggerhead populations in
Honduras, Mexico, Colombia, Israel, Turkey,
Bahamas, Cuba, Greece, Japan, and Panama have
been declining. This decline continues and is
primarily attributed to shrimp trawling, coastal
development, increased human use of nesting
beaches, and pollution. Loggerheads are the most
abundant species in U.S. coastal waters, and are
often captured incidental to shrimp trawling.
Natural predators include fishes, dogs, seabirds,
raccoons and ghost crabs which eat 90 of
hatchlings.Shrimping is thought to have played a
significant role in the population declines
observed for the loggerhead.
