Snikkers are grass snakes, approximately 2-3m long and 500 mm thick. They move silently through the high grass of plains and meadows in the rifts. Occasionally they lift the forepart of their bodies to look for enemies or prey. A tapering dorsal fin runs from the back of the skull to the tail. When the snikker spits venom the fin extends fully. Snikkers vary in color from pale green to a dark maroon during moments of excitement. The snikker can spit twice at full effect; then it must rely on its bite as its venom will be exhausted.
