thornbill. Reptiles and amphibians Over 90 species of reptile and 22 species of frog are known to inhabit the National Park. The most commonly encountered snakes in the Gorge are the keelback (Tropidonophis mairii), the green tree snake (Dendrelaphis punctulata) and the carpet python (Morelia spilota). The largest lizards in the Gorge are the lace monitor (Varanus varius) and the sand monitor (Varanus gouldii). Of the wide variety of skinks, the largest is the major skink (Egernia major) which occurs in a disjunct population. The most frequently encountered of the Gorge's frogs are the tusked frog (Adelotus brevis), the striped marsh frog (Limnodynastes peronii), and the cane toad (Bufo Marinus). The introduced cane toad is currently implicated in the local disappearance of the northern quoll, once thought extinct all over QLD, a small population was established not long ago after 30 years of not one sighting of this critter, was found on a spotting job(Dasyurus Hallucatus). freshwater turtles such as Kreffts river turtle (Emydura krefftii) and the saw-shelled turtle (wollumbinia latisternum) are in strong numbers in Carnarvon Creek, commonly seen sunning themselves on rocks and logs during the middle of the day. Invertebrates The National Park's invertebrate species are extremely diverse. Several species of insect have their entire distribution within the Park's boundaries, and are joined in this category by at least four species of land snail. Butterflies are a feature of Carnarvon Gorge's fauna. Large aggregations of common crow (Euploea core) butterflies can occur in Carnarvon's cool, moist side gorges when the animals gather to overwinter. Carnarvon Creek is also home to large numbers of invertebrates, many of which are the larval stages of winged insects such as dragonflies. Visitors to Wards Canyon have the opportunity to observe these creatures easily in the clear, shallow, spring-fed stream.
