Final answer:
Insectivores primarily feed on insects and their dental arcades have sharp pointed teeth for gripping and tearing insects, as well as molars for crushing and grinding the soft body parts.
Step-by-step explanation:
Insectivores are a group of animals that primarily feed on insects. They have specialized dental arcades that are adapted for capturing and consuming insects.
Key characteristics of an insectivore's dental arcade include sharp pointed teeth for gripping and tearing the exoskeleton of insects, as well as molars for crushing and grinding the soft body parts of insects. These adaptations allow insectivores to efficiently consume their prey.
Examples of insectivores include anteaters, hedgehogs, and shrews.
