Answer:

seal, dolphin .......

Answer 2

Snake, Crocodile, Lizard, etc.

All the animals have ears but not all have visible outer ears, some have invisible ears or internal ears. Animals who are said to have invisible ears either have holes on the side of their head, instead of ears, or have receptors inside their head.

The receptors inside the head of the animals receive the vibrations from the external environment which act as a signal for the animal. Snakes are the most common example for this as they receive the vibrations from the external environment.
