What is a mammal?

- Fur (pelage)

- Mammary glands

- 3 inner ear ossicles (bones)

Do you think the mammals in Belize will be the same as the mammals in WV/V?

Why?/Why not?

- No cold season, but dry season

- Fruit everywhere

- Dense canopy very little light reaches ground ……..

Most of the vegetation (food/cover) is in the canopy so that is where you will find most of the mammals

If there are spp. of mammals in WV that are also found in Belize what characteristics would they likely exhibit?

- arboreal (at least partially)

- dietary generalists (omnivores)
