Describe the incisors of these different organisms. The shape of the skull gives the cougar very powerful jaws. The eyes of the cougar are moved to the front of the skull to enable to see its prey. The eyes of the horse are on the sides of its head to be on the lookout for predators. Examine the complete skeletons of the rabbit and the shrew-mole.
Shrews have small eyes because they live underground.
Since they live in a fairly lightless environment they don't have a need for eyes and have lost them over evolutionary time. Also eyes can be a liability if they are always being poked by roots in the underground environment. The forelimb of the shrew is shorter than the hindlimb. The arm bones are also bigger around in the forelimb. Shrews use their forelimbs to dig tunnels and have evolved these shorter, more powerful arms to aid them in this.
