Cottontail Rabbit Skull

Photograph of a cottontail rabbit skull


The cottontail rabbit skull is about 3 inches (6.5 cm) from front to back.

Notice the large nipping teeth; cottontails like other lagomorpha have two sets of incisors. It has no canines and very flat molars for grinding.

Notice also that it has a great deal of webbing instead of solid bone. This makes its skull lighter. Why would that be important to a rabbit? How does a rabbit escape its enemies?

This *herbivore's* jaw is quite loose so it can move from side to side to grind its food.

The cottontail rabbit's eyes are on the side. This helps it watch for its *predators*.

Relative to the total size of its skull, do you think its brain cavity is large? How could you find out for sure?
