MUDPUPPY
Necturus maculosus
DESCRIPTION
Mudpuppy (Necturus maculosus) is commonly known as the Waterdog and is a large, aquatic salamander characterized by its external gills, which are feathery and protrude from the sides of its head. This species has a robust body, typically gray to brown in color, with dark mottling that provides camouflage in its natural habitat. Mudpuppies are primarily nocturnal and are known for their aquatic lifestyle, often residing in rivers, lakes, and ponds, where they can be found hiding under rocks or in submerged vegetation.
FUN FACTS
- Mudpuppies are unique among salamanders because they retain their gills throughout their entire lives, a trait known as neoteny
- This adaptation allows them to thrive in aquatic environments where they can efficiently extract oxygen from the water
- | They are also known for their regenerative abilities, capable of regrowing lost limbs and even parts of their heart and eyes
- This remarkable regeneration is a subject of scientific research, as it may provide insights into healing and tissue regeneration in humans
