Sand is the Basis of the Sea Turtle Food Chain
Walking along the shore with your bare feet in the sand is a marvelous sensation. But sand is more than just a
pleasant walking experience; it is the very beginning of the sea turtle food chain as well as the
other aquatic animals that make their home beneath the oceans of the world.
Beach erosion and urban sprawl is the cause of vanishing shoreline taking along with it the sand that is the start
of the aquatic food chain. The food chain identifies who eats what. There are many reasons why sand is not making
it into the water where it needs to be including dams that cut off the flow of water from the mountains and
seawalls which affect sand on the ground level.
Because the food chain is such a fragile entity, when one specific element is removed, it causes a ripple effect
throughout the entire chain. The shallow tide pools are an important element in young marine creatures making it
into adulthood. It is there they can find nourishment as well as shelter from the larger animals that prey upon
them.
Not much is known about what happens to baby sea turtles if they make it past their initial travel to the sea, but
you can expect that they find a safe haven where they can hide and forage for food so that they may grow into the
giants who are more familiar to us. It is thought that they use the light of the moon to ride the wave crests
safely above their predators to the safer environs of the shallows.
The Impact on the Sea Turtle Food Chain
When one species is impacted along the food chain, any species that is higher up is directly impacted. If the
denizens of the sand are removed, then those that feed upon them will have nothing to eat, and so on it goes up the
line. Sand plays an important part in many sea creatures breeding habits. Sea turtles swim to shore to lay their
eggs deep in the sand and when their young hatch, they scramble to the waters to begin their journey. Many don't
make it for a variety of reasons such as the nest is covered by water at high tide because of beach erosion and
they can become confused by the lights of housing developments mistaking it for moonlight.
Sea turtles eat a variety of foods including vegetation and small animal
life. When the lower denizens of the food chain are affected, then in turn the larger sea animals are affected as
well. Nature knew what she was doing when she created each and every creature, and all depend upon each other in
order for an ecosystem to stay healthy and thriving.
Humans have so much to do with the sea turtle food chain as well as the food chain of many other creatures and it
is time to look to ourselves to learn what can be done to lessen our effect on the natural world before there is
nothing left but an empty landscape.
Pet Turtle Care Tip #1
Turtles are members of the Reptile family and they are some of the oldest living creatures
on the planet. They have been around for more than two hundred million years. This makes them as
old as the dinosaurs. There are hundreds of different kinds of turtles all over the planet.

Pet Turtle Care Tip #2
Sea turtles are the most popular of all of the turtles. These are also some of the largest
creatures—some sea turtles can grow to more than six feet in length and weigh hundreds of pounds.
Scientists think that sea turtles are actually land creatures that went back into the water and
never came out. Over time their limbs evolved to make them stronger swimmers and to keep them in
the water: their front appendages are actually flippers.

Pet Turtle Care Tip #3
All turtles, even sea turtles, are air breathing creatures. While some turtles can stay
under the water for hours at a time, they all must surface at least once a day to stay alive. There
is one turtle, the giant turtle that only has to surface once a day to take in air. There are some
studies being done to see if some species of turtle might be able to draw oxygen from their cells
much like some fish use their gills to breathe.
