Etymology
the word 'leatherback' is a transparent english compound, formed from two native old english roots. it is a descriptive name coined to identify the largest living sea turtle, dermochelys coriacea, by its most distinctive anatomical feature. the term 'leather' directly refers to the unique, rubbery, leather-like texture of its carapace, which lacks the typical bony plates found in other turtles. the element 'back' plainly denotes the turtle's shell, resulting in a name that literally means "the one with a leathery back," providing a clear and logical link between its physical characteristic and its modern common name.
