KeelBack
Tropidonophis mairii
The Freshwater Snake (also known as the Keelback) is olive brown with irregular dark cross-bands. The body scales are strongly keeled, producing ridges that run along the snake’s body. Flecks of pale skin can often be seen through the scales. The belly is cream and usually flushed with a pink or orange tinge along the edges. Dark bars can be seen between the sutures on the upper lip scales. This species grows to 75 cm. Midbody scale rows 15 (rarely 17); ventrals 130–165; anal divided; subcaudals divided 50–85. Lives in well watered situations along creeks and in swamps but also found in eucalypt forests, heaths, pastures, parks and suburban gardens. Habits: This species is active both day and night. It is usually found at ground level, but can climb well (a specimen was observed 5 m up a melaleuca tree in a swamp on Cape York Peninsula).
