Francois’ Langur (Tonkin leaf monkey)

Presbytis francoisi - The langur lives in groups consisting of one alpha male, four to six females, and several young. These monkeys are about two feet tall, plus their long tails. They live in jungles near caves and cliffs as high as 100 feet. Langurs yell to scare off other groups, or to warn of a change in weather.
Interesting fact: Mature langurs are black and gray, but the infants are bright orange!

Serval

Leptailurus Serval - The serval is like a cat on stilts. It has very long legs and can jump up to ten feet in the air. Servals come from Africa, and usually hunt wild rodents and reptiles. They have been seen hunting flamingos from time to time.
Interesting fact: A serval will eat around 4,000 rodents in a year, which is actually a benefit to human farmers.
