4.4.2 Reptiles and Amphibians
Seventeen reptiles have been recorded from the Torrens Island area (Table 6). Two of these are Sea Turtles, which do not nest on the island and would at most be misplaced vagrants in the waters surrounding the Island. Most of the remaining fifteen species could possibly be present on Torrens Island, with seven species having been recorded on the Island in the past. Most of the reptile species require structure for shelter at the ground level, such as fallen timber, leaf litter, open shrub, grass and groundcover understorey. Management actions need to ensure that these microhabitats are retained or improved.

Scincidae Skinks Menetia greyii Dwarf Skink Y Y Small, active diurnal skink. Widespread across Australia. Has been recorded on Torrens Island.
Scincidae Skinks Morethia adelaidensis Adelaide Snake-eye Y Active diurnal skink, requiring ground litter and fallen timber. May be present on Torrens Island.
Scincidae Skinks Pseudemoia entrecasteauxii Southern Grass Skink Y Active diurnal skink, found “in a variety of forest and grassland habitats throughout its range; usually seen on or around fallen timber, or foraging in leaf litter.”
Scincidae Skinks Tiliqua rugosa Sleepy Lizard Y Widely distributed large skink. Shelters under “fallen timber, leaf litter, spinifex and other grasses”. Has been observed on Torrens Island.
Scincidae Skinks Tiliqua scincoides Eastern Bluetongue Y Widely distributed large skink. “Shelters at night in hollow logs, ground debris etc.” Has been observed on Torrens Island.
Elapidae Elapid Snakes Demansia psammophis Yellow-faced Whipsnake Y Not recorded from Torrens Island. Last nearby records are from the 1970s. Unlikely to be present on Torrens Island.
Elapidae Elapid Snakes Pseudonaja textilis Eastern Brown Snake Y Y Common diurnal snake. It has been recorded on Torrens Island.

Amphibians

There are no records of amphibians from Torrens Island, but four species have been recorded within a 5km radius of the extent of the Island. Given the close proximity of the sea to the site, and the lack of freshwater pooling to allow eggs and tadpoles to mature, it is considered unlikely that any frogs are present on Torrens Island. The two species that might possibly be present are the burrowing species Neobatrachus pictus and Limnodynastes dumerilii.

Myobatrachidae Southern Frogs Neobatrachus pictus Burrowing Frog Y Burrowing frog, often found well away from freshwater bodies, but requires standing water to breed.
