The land, water and air of this planet are home to different types of living organisms. After a number of years of arduous scientific research, scientists have classified these organisms for better comprehension of their traits. This classification has indeed even helped an ordinary human being to grasp certain distinct facets of each organism living on this Earth.
The nomenclature of sea turtles highlights their kingdom as Animalia, Class as Reptilia, Subclass Anapsida and Order Chelonii. Studies in this field have been able to identify 7 basic species of this animal. While most of the sea turtles, namely hawksbill, green, flatback, loggerhead, Kemp's Ridley and Olive Ridley turtles are slotted under the Family Cheloniidae, the leatherback stands alone in the family Dermochelyidae.
Sea turtles found in the marine or brackish surroundings show the presence of long and paddle-like flippers and streamlined carapace, both characteristics that assist them in their survival in water.
Sea turtles reproduce by laying eggs. The life of the young ones is often under the risk of predators until they attain maturity at the age of 30 years. However, in today’s scenario apart from animal threat, this reptile is also at a risk from human beings. Activities such as harvesting sea turtle eggs as food for the human race, getting trapped in fishing equipment, consumption of trash and coastal expansion have rendered all 7 species of sea turtles as endangered animals.
While the male members of this reptile prefer the sea, the females only visit the sea for the purpose of mating. Sea turtles are well known to cover vast distances to the score of thousands of miles during the act of migration, to and fro from their feeding areas to the nesting regions. In the year January 2008, the migration of a leatherback turtle was traced with the help of a satellite. Records showed the turtle covering a distance of 12,000 miles in 674 days.
