Editing Stridulation (section)

==Vertebrate stridulation==
Some [[species]] of [[venomous snake]]s stridulate as part of a threat display. They arrange their body into a series of parallel C-shaped (counterlooped) coils that they rub together to produce a sizzling sound, rather like water on a hot plate. The best-known examples are members of the [[genus]] ''[[Echis]]'' (saw-scaled vipers), although those of the genus ''[[Cerastes (genus)|Cerastes]]'' (North African desert vipers) and at least one bush viper species, ''[[Atheris desaixi]]'', do this as well.<ref name="SB95">Spawls S, Branch B. 1995.
