Because the rattle is a warning against predators - not a lure to entice prey. Snakes hunt by stealth, so using its rattle would likely scare prey away since they're 'programmed ' to be wary of strange noises.
Some other snakes that rattle their tails to warn off potential predators include the Massasauga rattlesnake, the Western diamondback rattlesnake, and the Timber rattlesnake. These snakes use their tail rattle as a form of defense when feeling threatened.
A rattle snake has no protection from a human,but it might would use his fangs
Rattlesnakes are best known for, and most easily recognized by, their rattle. They use it to scare offpredators.
The rattlesnake uses the tail to warn animals of their presence. It is thought that the rattle evolved during the time when North America was inhabited by huge herds of large hoofed mammals which posed a threat of the snake being trampled. The rattle serves to notify any animal that they should probably alter their route of travel to prevent an incident that could prove fatal to both snake and mammal.
It's used as a warning - to let animals (and people) know they're venomous.
Yes, this would be considered a mutation, but it is a mutation that is inherited from parent to some offspring. Frighteningly enough, these rattlesnakes without rattles are becoming far more common as many normal rattlesnakes are killed when they sound off their warning. this allows for those without rattles to survive longer and breed more, passing these mutated genes to more and more offspring.
Yes it can ! Rattle-snakes use heat sensitive pits to detect infra-red heat coming from their 'victim'. So long as they have this ability they will at least have a 'fighting chance' of survival !
No a rattlesnake does not use chemical to camouflage itself
Like most snakes, a dimoandback rattlesnake's first choice will be to hide or flee. However, if the snake feels it is cornered or that it cannot escape, it will rattle its tail as a warning. As a last resort the rattlensake will inflict a venomous bite, which is extremely painful and potentially fatal.
The tail of a rattlesnake consists of a series of interlocking hollow buttons that produce the rattle sound when the snake shakes its tail. Each time the snake sheds it produces a new segment for the rattle. It is used as a warning to potential predators or to large mammals that could step on the snake. See the image above of a rattle from a rattlesnake.
a rattlesnake uses mimicry to look like other animals
It is there defense or warning to larger animals to keep from being stepped on. One theory is that the rattlesnake developed this appendage while bison roamed in the millions across North America to prevent being stomped on.They do it to warn animals, or to make animals sounds, like why dogs bark. They rattle with the loose segments at the end of the tail. depending on how it rattles, it may warn other animals to go away or leave it alone
