Water collection has been shown in some rattlesnakes, though the nanostructure of the scales is thought to be more significant than the macrostructure (keel) of the scales. [6] In some viperines, most notably those of the genus Echis, the lateral scales are not only keeled, but the keels have minute serrations. The snakes use this in a warning ...

[ 37 ] Snakeskin, with its highly periodic cross-hatch or grid patterns, appeals to people's aesthetics and have been used to manufacture many leather articles including fashionable accessories ...
A snake with keeled scales, and a narrow head that is wider than the neck, the Pacific gopher snake also displays a protruding rostral scale on the tip of the snout. The two most common base colors are straw and straw gray, though the species' color varies widely. [4]
The dorsal scales are arranged in 19 rows, strongly keeled, with outer rows smooth. The ventrals number 125–158, the anal is divided, and the subcaudals number 64–90. Coloration is very variable, consisting of dark spots arranged quincuncially and often separated by a whitish network, or of black longitudinal bands on a pale ground, or of ...

[3] [5] The females are larger than the males, which is unusual for this group of snakes. [6] Usually, 21 rows of keeled dorsal scales occur midbody. [3] [7] Males have 141 or fewer ventral scales; females have 144 or fewer. [3] It is sometimes referred to as the horned rattlesnake because of the raised supraocular scales above its eyes.
The snake is brown to olive with narrow, irregular cross-bands or blotches of darker brown. The belly surfaces are greenish-grey or olive-cream, often with darker blotches. The mid-body scales have a raised keel or carinated appearance. The coloration and scale structure has led to some confusion with the non venomous keelback snake. It grows ...
