Figure 14.20: Bats, like this Egyptian fruit bat, belong to another subgroup of placental
mammals. Ecologically, fruit bats play an important role in seed dispersal. ( 24 )
- Premolars – shearing and grinding (herbivores, like cows, have flat premolars and
molars for grinding vegetation) - Canines – piercing (carnivores, like lions, have long and strong canines.)
- Tray of actual, or illustrations of, various mammalian limbs, numbered (for feet, could
also show cast of track, to see if students can match the track with the actual foot type) and
pictures of habitats or actual animals, lettered:
- Toe ending in claws – tiger (climbing and running)
- Toes with hooves – horses and cows (running)
- Fins – aquatic mammals (swimming)
- Wings – bats (flying)
- Highly mobile limbs – monkeys (climbing in trees)
- Answer sheets, listing numbered mammal teeth and limbs
Directions:
One group of students examines the tray of mammal teeth and pictures of diets and indicates
on the answer sheet the correct matches. The other group of students examines the tray
of mammal limbs and pictures of habitats and similarly matches these up with the correct
answers.
