What are the ‘ears’ of a sea slug really?
A Tufts
B Noses
C Whiskers
Not so much ears as noses, rhinophores, known as chemosensors, allow sea slugs to smell and taste their surroundings. Chemicals that have dissolved in the water are detected by the hairs on the rhinophores. By sensing those chemicals, the sea slug knows how close a food source or potential mate might be.
The correct answer is Noses.
