Reptiles

Nine snakes and 31 lizard species have been identified on the islands and cays of the Great Barrier Reef Marine Park.

Snake species include:

• amethystine python (Morelia amethistina)
• death adder (Acanthophis sp.)
• a blind snake (Ramphotyphlops polygrammicus)
• brown tree snake (Boiga irregularis)
• common tree snake (Dendrelaphis punctulata)
• slaty-grey snake (Stegnotus cucullatus)
• yellow-faced whip snake (Demansia psammophis)
• collared whip snake (Demansia torquata)
• brown-headed snake (Furina tristis)
• an undescribed species (Cacophis sp.)

Lizards include six species of gecko, one legless lizard, two goannas and 22 species of skinks.

Scientists believe that many species have yet to be discovered as there have been few systematic studies.

Amphibians

At least seven frog species have been identified within the Park, though researchers believe the actual number of species is probably higher.
