2. This family of bats occurs only in the Old World and feeds mainly on fruits and nectar.
3. All modern species of this fully aquatic order of herbivorous mammals occur in relatively warm waters, but one large species that became extinct within historic times occurred in the much colder waters of the northern Pacific Ocean.
4. This family of carnivores contains a genus that is specialized for feeding on ants and termites
5. This family of bats has more species than any other bat family, occurs worldwide, and mainly consists of insect eaters.
6. This family is highly successful and widespread today, and includes more genera (>200) and species (>25% of all living mammals) than any other family of mammals.

12. This family contains the the largest bodied rodents found today
13. This family of Caviomorph rodents has a South American origin, and most species occur in the neotropics today, but one has extended its distribution far north, including Texas.

15. External furred cheek pouches occur in the following two familes
16. These small, insectivorous mammals have a long, movable snout and long hind limbs so they can hop bipedally.

19. The only carnivorans in Madagascar belong to these two families
20. In this family, the hind foot capable of forward rotation for terrestrial locomotion via hindfoot propulsion. For aquatic locomotion, the forelimbs are used for propulsion, hindlimbs for steering
21. ALL of the following families have an auditory bulla divided into two chambers EXCEPT
22. Which of the following primate taxa occurs only in Madagascar
23. Most members of this carnivore family occur in the New World, with the exception of the Ailurus, the lesser or red panda

26. Which of the following primate taxa feeds mostly on leaves
27. This family of arboreal gliders has a tooth comb of pectinate incisors
28. In this family, the hind foot is not capable of forward rotation for terrestrial locomotion. For aquatic locomotion, the forelimbs are used for steering, hindlimbs for propulsion,
