This one went past the speeding mammal so fast, that it showed only a blur of dingy brown markings on its back and a gleam of marbled red blotches on its belly, as it disappeared in a hole which sloped under the bank. Although not venomous, the banded watersnake has within its flat triangular head a mouthful of sharp teeth which it is always willing to use, and is an exceptionally active, powerful serpent.
