Marine Life on Sea Turtles“There are only seven species of sea turtles in the world and only one is listed as threatened” (Global Sea Turtle Network). Sea turtles have been swimming in the seven seas for over one hundred and ten years, even though they have survived natural predators, climate change and the extinction of the dinosaurs. Sea turtles face more danger than they did a long time ago, due to increased technology, fishermen finding new places where catching fish is promising, oil spills and the discovery that some parts of sea turtles are very valuable. More and more sea turtles are being killed, sold on the black market or trapped in fishing nets. Society must do more on beaches, in oceans and in local communities to prevent sea turtle species from becoming extinct. The seven species of sea turtles are: “Leatherback sea turtle; the largest of the sea turtles, their shell ranges from fifty-two to seventy inches in length, they can weigh up to a ton and nest on tropical beaches, the green sea turtle is found primarily in the Gulf of Mexico and on the West Coast and weighs one hundred and fifty to four hundred and forty pounds, their shell is from thirty-two to forty-eight inches long. The largest green sea turtle ever recorded was five feet long and weighed eight hundred and seventy-one, the Kemp Ridley sea turtle shell is twenty-four to thirty inches and nests in the Gulf of Mexico; they are the smallest of all sea turtles, the Olive Ridley sea turtle shares the same size as the more abundant Kemp's Ridley sea turtle; ranging across the tropical Pacific, Indian and Atlantic oceans, flat-backed sea turtles nest only on Australian beaches larger than what the two Ridleys considered the most mysterious of sea turtles; little is known about what they eat or where they migrate after nesting...... middle of paper ......t Sea Turtles: Threats to Sea Turtles."
