The chameleon, a small lizard generally measuring 6 or 7 inches, has a tongue several inches longer than its body. With a thrust of this remarkable appendage it can catch insects some 10 inches away.

A female mouse may spawn as many as ten litters of eight to ten young during her lifetime–which generally is less than a year. The gestation period is three weeks, and the young mice reach maturity in only ten weeks.

Wolves are highly territorial animals, and generally establish territories far larger than they require to survive; in order to assure a steady supply of prey. Territory size depends largely on the amount of prey available: in areas with an abundance of prey, the territories of resident wolf packs are smaller.
