The warmer a rattlesnake, the faster it vibrates its tail. [6] Rattlesnakes tail-vibrate faster than other snakes, with some individuals nearing or exceeding 90 rattles per second. [7] [8] This makes rattlesnake tail vibration one of the fastest sustained vertebrate movements—faster than the wingbeat of a hummingbird. The movement is possible ...
These results strongly support the hypothesis that tail vibration preceded the rattling system as a behavior and allowed for the rattle to be selected for once developed. Even a small, underdeveloped rattle early in the evolution of the rattling system could have been advantageous if tail vibration was an ancestral behavior. [60]
Aug. 18—Q: I need information on humane rattlesnake-proofing techniques for dogs. It seems to me that keeping your dog on leash would be a better solution, so I don't need it for myself. In ...
Like other rattlesnakes, its tail has a rattle, which is composed of keratin. Each time the snake sheds its skin, a new segment is added to the rattle. However, the rattle is fragile and may break off, and the frequency of shedding can vary. So, the snake's age cannot be determined by the number of segments or length of the rattle.
Tail wagging has long been associated with a pup's mood, but the fascinating -- and often telling -- things about the appendage don't stop there. Here are 10 things you didn't know about dogs' tails.
These DNA kits for dogs give you way more information than your dog’s breed composition. Many of the kits can be upgraded to include more health and trait testing or allergy and age tests.

As with other rattlesnake species, prairie rattlesnakes will rapidly vibrate their tails, which produces a unique rasping sound to warn intruders. [12] Prairie rattlesnakes prefer a straight migration path while migrating even in human-dominated environments because it leads to a higher chance of survival and better body condition throughout ...
