Why Do Animals Have Tails?
Learn How To Read The Tale Of The Tails
Just imagine how lousy it would be if we humans had tails. They'd be forever getting caught in our recliners or chaise lounges, where would we put them while flying down Space Mountain, and we certainly wouldn't look as great as we now do in a pair of Speedos or yoga pants.
They'd certainly be a problem for us humans. Animals are different, though. Tails are a critical part of their anatomy. Tails enable them to communicate, ambulate and thermal regulate; and some even regenerate.
Some times it's hard to tell where the animal's body ends and its tail begins. Take snakes, for instance. Do they even have a tail or are they all tail. They have a tail, but to tell where it begins, you'll have to get pretty personal with the snake.
If you could convince it to lie on its back, you'd have to locate the cloaca. Pronounced clo-ache-uh, it's the orifice through which waste and, in the case of oviparous (egg-laying) animals, eggs pass.
In the case of snakes, the cloaca fits the symmetry of the belly plates, so that makes it a little more difficult to locate, unless you sort of ask the snake to bend over and cough. So, to simplify things just sort of jiggle his hiney a bit, and the cloaca will expose itself. From there to the tip of its tail is the tail.
Other reptiles use their tales as weapons, and formidable ones at that. If you've ever been tail-whipped by an iguana you know what I mean. Some amphibians use their tails as decoys when threatened by predators.
They'll wiggle their tails to lure the predator to attack that appendage, and when it does it will either rip the tail off or the amphibian will jerk itself free from the tail. Then he'll just regenerate a new one.
The new one usually doesn't come back as long or defect-free as the original, but it gives the owner a new lease on life. Other defensive uses of the tail are exemplified by the bee, scorpion and skunk. The latter just has to be able to raise it.
A little closer to home, we see how dogs and cats use their tails to communicate. The position and/or activity of the tail tells others whether the animal is feeling aggressive, submissive, happy-go-luck, interested or just chillin.
Squirrels and beavers use their tails to signal alarm. Squirrels will flick their tails back and forth rapidly in the presence of danger, while beavers will smack the water with it, making a fairly thunderous noise.
The tail is an important tool in animal locomotion, too. Notice how precisely a cheetah zig-zags in unison with it's prey during the chase. Without a tail the big cat would probably wipe out at the first zig.
Snow leopards (above, right) use their huge tails for warmth and to aide in negotiating their rugged habitat by acting as a rudder and helping them to maintain balance.
We little cat owners all marvel at how our pets negotiate knick-knack shelves, mantels, bookcases and other "mine-field" locations without (usually, that is) knocking stuff off.
The really lucky animals have prehensile tails, which means they can eat a banana, scratch an itch, cuff a cocky juvenile, and groom their neighbor all at the same time because they're holding on to a tree for dear life with their tails.
Wild animals, such as wolves, coyotes, and snow leopards use their tails to help thermal regulate. When it's cold, they sleep with their bushy tails draped over their noses. This protects that noble proboscis and helps warm the air they breathe at the same time.
Some birds, such as peacocks and turkeys, use their tails in courtship rituals. They fan them out and rattle them, which is meant to earn the attention of the hens. They also use the display as a threat towards their own species or defense-bluff against predators.
You might be a turkey if your last words are, "C'mon,you mangy, smelly, disgusting coyote, make my day."
With all those neat things you can do with a tail, now don't you wish you had one?
