Sea Turtle Feeding
What do Sea Turtles Eat?
There is quite a bit of difference when
it comes to the feeding habits of sea turtles. Some of them
will only consume meat while others consume plants. There are a
few species where they start off consuming meat when they are
young. However, as they mature they change to a diet of only
plants. This is why you will notice such a different in the
overall jaw structure of the various types of sea turtles.
Green Sea Turtles have jaws that are serrated. The young
start out being carnivores but as adults they only consume
plant life. When you look at the jaws of both Loggerheads and
the two Ridley’s species, you will notice that they are very
powerful. This allows them to be able to crush as well as to
grind up the meat that they consume from various types of
aquatic life.
The Hawksbill Sea Turtle has a beak like structure to their
jaws. This is because they need a pointy object that allows
them to remove food from crevices in the corral reefs. That is
where their foods sources of sponges, squid, and shrimp are
found. Leatherback Sea Turtles can only consume very soft foods
such as jellyfish due to the design of their jaws. They are
very similar to a pair of scissors.
Sea turtles can alter their metabolism when food becomes
scarce too. As a result they can go up to three months without
food. This is one way that they have been able to successfully
adapt to their natural habitat. However, when a lack of
available food continues to be a problem, many of them may
starve. Others move far away from their natural habitat in
order to find a residence that does offer them food.
Research has also determined that all sea turtles are
opportunistic when it comes to feeding. That means they will
consume what they can get their hands on when regular supplies
of food are scarce. Before they do this though they will go to
great lengths to find what they really want. This is more
evident with the older sea turtles behaviors than with the
younger ones.
The sea turtles that migrate also find food along the way
back to their original location. The females consume large
amounts of food before they go to land in search of a place to
nest. They will dig an area and then deposit their eggs in it
before returning to the water. This can take several hours and
it does take a great deal of energy for them to complete the
process.
The amount of food that a sea turtle will consume depends on
many factors. The species that it is and what it eats are the
biggest factors. There is also the time of year as they tend to
consume more in the summer months while migrating and getting
ready for mating. In many areas though it is getting harder and
harder for them to find their foods of choice. This is due to
the number of fishermen in the area and their sophisticated
equipment that allows them to gather large amounts of aquatic
life for profit.
While sea turtles are busy looking for food, they also have to
make sure they don’t become food. Some of their well known
predators include fish, sharks and whales while they are in the
water. On land they are also in danger from birds, raccoons,
dogs, and crabs. The various types of coloring on their bodies
can camouflage them in many instances. Many younglings die due
to such predators but larger sea turtles are less likely to
become a meal.
