Answer 1

Answer:

Snakes, lizards, dolphins, frogs and birds do not have visible ears. They have other types of auditory organs such as eardrum, tympanum etc. These are internal and not visible to the human eye due to the lack of external pinna as in humans. Most animals have ears but not external pinna.
