Trivia: What part of a rodent’s body never stops growing?
Ears
Tail
Nose
Teeth
The correct answer is Teeth
So why is this answer correct? : One of the most defining characteristics of rodents is their teeth. Rodents have two pairs of upper and lower incisors that don’t have roots and never stop growing. Rodents grind their teeth against each other or other surfaces to prevent health issues from overgrown teeth.
