What is a dental characteristic of insectivores?

As this type of diet is not nutritious, insectivores are small creatures. Hedgehogs typify this dentition, where the teeth have lots of sharp, pointed cusps that fit into pits in the opposing teeth and act like a pestle and mortar (Figure 4.22).

Which is a Folivorous?

In zoology, a folivore is a herbivore that specializes in eating leaves. Mature leaves contain a high proportion of hard-to-digest cellulose, less energy than other types of foods, and often toxic compounds. For this reason, folivorous animals tend to have long digestive tracts and slow metabolisms.

What do Folivores eat and give an example?

For example, primates that eat bark, insects, wood, or exudates may all have procumbent incisors for removing bark from trees to obtain food. … Relative to the size of their molars, folivores tend to have smaller incisors than do frugivores, because leaves require less incisive preparation.
