Sea turtles are one of the Earth’s most ancient creatures. Sea turtles are not like most turtles. Some can put their heads into their shells but sea turtles cannot. The fact that they cannot hide their heads in their shells makes them more vulnerable to predators because the shell is a hard protective cover and their heads and fins are easily destroyed by teeth or motors.
Sea turtles diets contain seaweed, crabs, shrimp, sponges, snails, algaes and mollusks, depending on the species. Different sea turtle species eat greens like sea grasses. Leatherbacks eat jellyfish and soft-bodied animals. Loggerheads eat heavy-shelled animals such as crabs and clams. Hawkshells eat sponges and other invertebrates and the Kemp’s Ridley prefers crabs.
Sea turtles spend most of their time in water. We know this because they only leave the ocean to lay their eggs. Sea turtles can only be found in the warmest waters throughout the world. Some of them migrate for 1,400 miles between their feeding grounds and the beaches where they nest. The female sea turtles go to beaches and dig out a nest with their back flippers to bury their eggs, then return to the ocean. The hatching eggs may take as long as a week to dig themselves out. Predators sometimes hunt for sea turtle nests for the eggs.
Sea turtles are in danger of extinction. This is because of fisheries, direct take-when motor boats hit them head-on, as well as pollution. Human construction causes the sea turtle population to die down because when construction happens where they would lay eggs, this habitat is destroyed; they have no place to build their nests or lay their eggs. The sea turtle population decreases because the human population takes away the space that the sea turtles would use to live and breed.
