D = Dictionary.com REPTILE NOTES A reptile is a vertebrate that has dry, scaly skin, lungs, and terrestrial eggs with several membranes. The first mention of this species on Saint Barthélemy was made by Questel and Boggio in 2012 to Petit Cul-de-Sac. Most reptiles have an epidermal covering on their skin which is composed of beta-keratin. Frogs are of particular concern because an invasive fungus has recently caused many populations to collapse.

The shape and size of these scales defer depending on the species. Plankton-eating fish—vital food sources for the plesiosaurs and mosasaurs—also dropped in number, triggering the reptiles’ disappearance.
