Jackrabbit Black-tailed

jackrabbitbg: JackrabbitCOMMON NAME: Jackrabbit Blacktailed

SCIENTIFIC NAME: Lepus californicus

DESCRIPTION:

Originally called jackass rabbits because of their large ears. This 6-8 pound mammal has a short black tail, very long hind limbs and feet, and short, thick fur. Its large eyes are placed back on the head so the jackrabbit can see in front, behind and overhead at the same time. The black tips on the ears and topside of its tail distinguishes this species from other jackrabbits. The long ears provide for release of excess body heat ; the blood vessels expand to allow the blood to cool before reentering the body. It keeps its brownish coloring year around.

Jackrabbits are true hares. They do not dig burrows, and their young are born with their eyes open and fully furred. The jackrabbit can reach speeds of 30 - 35 mph when panicked. They can leap (bound) up to 20 feet.
