Bighorn Sheep - Photo of the Day - April 23rd, 2011
"Bighorn Sheep"
Bighorn sheep are named for their large, curved horns atop their heads that weigh around 14 kg on a male. Though both sexes have horns, the males are much larger, and are utilized in the headbutting battles for female's attention during mating season. These horns advertise to females a male's health and age since they continuously grow through his life. Their body also has double-layered skulls supported by struts and a huge tendon linking the head and spine to cushion the blows from their rival.
