Answer 1

Mud puppies are known for their distinctive calls. These amphibians are unique in being able to vocalize underwater through sounds like 'barks', which serve purposes such as mating and deterrence.

Step-by-step explanation:

Mud puppies, a type of salamander found in North America, are known for their distinctive calls. These amphibians are unique in that they retain their gills throughout their entire lives, a trait called neoteny. Mud puppies are often heard during night time making sounds that are described as 'barks' or 'howls'.

These vocalizations are quite unusual for amphibians, and that's why the mud puppy is notable for its call, particularly during the breeding season. Their calls serve various purposes such as attracting mates, deterring competitors, and possibly even scaring off predators. Option B is correct.

While they might also be recognized for features like their external gills and their aquatic habitats, it is their vocalizations that are most remarkable. The mud puppy calls can be heard underwater, making them one of the few amphibians that can be identified by sound while submerged.
