Dermochelyidae is a family of sea turtles which has seven extinct genera and one extant genus, containing one living species, the leatherback sea turtle (Dermochelys coriacea). The oldest fossils of the group date to the Late Cretaceous .
The turtle shell is a shield for the ventral and dorsal parts of turtles (the order Testudines), completely enclosing all the vital organs of the turtle and in some cases even the head. [1] It is constructed of modified bony elements such as the ribs, parts of the pelvis and other bones found in most reptiles.
Some phylogenetic studies determine the leatherback turtles in the family Dermochelyidae to be their closest living relatives, with both these families being monophyletic. [ 4 ] [ 12 ] Conversely, the phylogenetic analyses conducted by Joyce (2007) and Anquetin (2012), which included one protostegid species ( Santanachelys gaffneyi ), recovered ...

The dive profile is consistent, with an initial phase of fairly steep downward swimming at about a 40° descent angle, stroking at about once in 3 seconds with the flippers, followed by a gliding phase, which starts at a depth that varies with the maximum depth of ...
