Mandrill
The mandrill is an omnivore. It usually consumes plants, of which it eats over a hundred species. It prefers to eat fruits, but will also eat leaves, lianas, bark, stems, and fibers. It also consumes mushrooms and soil. Carnivorously, mandrills mostly eat invertebrates, particularly ants, beetles, termites, crickets, spiders, snails, and scorpions. It will also eat eggs, and even vertebrates such as birds, tortoises, frogs, porcupines, rats, and shrews. Mandrills likely will eat larger vertebrates when they have the opportunity, such as juvenile bay duikers and other small antelope. Large prey are likely killed with a bite to the nape with the mandrill's long canines. One study found the mandrill's diet was composed of fruit (50.7%), seeds (26.0%), leaves (8.2%), pith (6.8%), flowers (2.7%), and animal foods (4.1%), with other foods making up the remaining (1.4%).
Antelope squirrel
The typical life span of a wild antelope squirrel is 2–4 years; although, in captivity they have been known to survive 11 years. Males and females are sexually mature by the end of their first year. The reproductive season last from February to March with typically one litter per year. Each litter contains between 5-14 young that will wean around 8 weeks and make their first appearance above ground. All antelope squirrels give birth to and nurse their young in burrows. However, they do vary in the way they dig the burrows. For example, the white-tailed squirrel digs shallow burrows under brush or will use the abandoned burrows of kangaroo rats. These squirrels are not monogamous and have been known to mate with multiple partners each breeding season.
