Sea Turtles

Green Turtle (Chelonia mydas)


The Chelonia mydas, or Green Sea Turtle, gets it common name from the green colouration of its subdermal fat, as well as their green or olive coloured shell, which varies depending on the habitat they reside in as well as their diet. A single pair of prefrontal scales can be located on the head, with four lateral, or costal, scutes being present on the smooth carapace of the shell.  Four inframarginal scutes without any pores present on the plastron of the shell. C. mydas are able to reach overall lengths of around 1.4 meters, making them the largest hard-shelled species of sea turtle on the planet, and weights of up to 180kg. Adult male and female individuals can often be told apart by the length of their tail.


The C. mydas species can be described as omnivorous, with their diet consisting of different algal and seagrass species, as well as many different types of invertebrates.

Protection status

Currently, the C. mydas species is considered to be endangered with regards to its survival, with a decreasing population trend worldwide.
