B. Congo eel
C. Hellbender
D. Mudpuppy

Answer 1

Hint: Necturus is a species of salamander They live entirely in aquatic ecosystems in the eastern part of North America in lakes, rivers, and ponds. These organisms have both gills and can also respire through their skin because skin and lung respiration alone is not sufficient for gas so that they must rely on external gills as their primary means of gas exchange.

Complete answer: Necturus is a species of salamander in the genus Necturus, which is commonly called the mud puppy. They are usually a rusty brown color and can grow to an average length of 33 cm. Mudpuppies are nocturnal creatures and come out during the day only if the water in which they live is murky. Their diet consists of almost anything they can get in their mouths, including insects, mollusks, and earthworms. Once a female mudpuppy reaches sexual maturity at six years of age, she can lay an average of 60 eggs. N. maculosus specimens live in streams, lakes, and ponds in the eastern part of North America. In the more northern sections, they are called mudpuppies, and in the southern portions, they are called waterdogs. The mudpuppy hides under covers such as rocks and logs during the day and becomes more active at night.
Therefore, the correct option is D.

Note: This species of salamander is called mudpuppies due to its distinct color and the fact that they often inhabit muddy ecosystems. They have distal portions of the gills and can respire through their skin. This enables them to survive in diverse locations. They are found throughout North America. They have flattened limbs which they use to crawl through mud or bottoms of streams and ponds.
