Musth is a period in which adult elephants experience “testosterone overload,” inducing extreme levels of agitation, violent tendencies and rogue behavior. During musth, elephants discharge a thick tar-like substance called temporin, a warning sign that the elephant may charge in a dangerous frenzy with no apparent provocation at all.
For male moose and elk, this testo-explosion is called “rut,” during which the animals fight with each other.
And that urge to fight is simply uncontrollable. Elephants will charge almost anyone or anything in a seemingly mindless state of enraged fury. Moose in rut go head-to-head with each other (literally) in an attempt to demonstrate who is the superior male.
It’s a macho-fest of the animal world, where “kill or be killed” is replaced with “kill and impress the girls!”
The etymology of musth is very apropos. The word derives from the Persian “mast” meaning “intoxicated.” When raging in a manic killing craze, an animal exhibits the same level of judgment one might expect from someone who has ingested a dozen glasses of rum and coke (minus the coke).
