Because they have a 'beard' of spiky skin under their throat
Because they have a beard of fur
Because they have long whiskers

Insects and plants
Only insects
Only plants
Small mammals
By moving to different temperatures in their environment
By drinking cold water
By panting
By sweating
Puffing up their 'beard' and turning it black
Barking
Playing dead
Running away on two legs
Bright eyes and active behavior
Aggressive behavior
Constantly sleeping
Hiding all the time
Deserts and arid scrublands
Coastal areas
Mountainous regions
Tropical rainforests
By changing colors and body language
By releasing scents
Through telepathy
Through vocal sounds
