Only some species emit peti similar to human ones. This system is used as a defense mechanism: the noise is heard up to two meters away.
Yes, snakes also emit peti, but but The purpose of these sounds is very different from that of human peti and probably works like a Defense mechanism.
Short, but powerful. The peti are emitted, however, only by two species of North American snakes, the western coral snake (Euryxanthus MICRURODES) and the western hook snake (Gyalopion Canum), the noises in question consist of almost crackling identical to our flatulence and they feel when i reptiles expel air by contracting the cloacapart of their digestive system. Each crackling lasts less than two tenths of second, but it can be repeated several times and is audible up to two meters away.
A noisy defense. The precise purpose of the “peto” is still partly unknown, but scholars hypothesize that it is a way to remove or disorient possible predatorsthus being able to escape you more easily. This circumstance could be confirmed by the fact that both species share an identical desert habitat And over time they had to face the same threats.
