Axolotls are Masters of Regeneration

The axolotl (/ˈæksəlɒtəl/, from Classical Nahuatl: āxōlōtl [aːˈʃoːloːtɬ] (About this sound listen)) also known as a Mexican salamander (Ambystoma mexicanum) or a Mexican walking fish, is a neotenic salamander, closely related to the tiger salamander. Although the axolotl is colloquially known as a “walking fish”, it is not a fish, but an amphibian. The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of developing lungs and taking to the land, adults remain aquatic and gilled.

Axolotls should not be confused with waterdogs, the larval stage of the closely related tiger salamanders (A. tigrinum and A. mavortium), which are widespread in much of North America and occasionally become neotenic. Neither should they be confused with mudpuppies (Necturus spp.), fully aquatic salamanders that are not closely related to the axolotl but bear a superficial resemblance.

As of 2010, wild axolotls were near extinction due to urbanization in Mexico City and consequent water pollution, as well as the introduction of invasive species such as tilapia and perch. They are currently listed by CITES as an endangered species and by IUCN as critically endangered in the wild, with a decreasing population. Axolotls are used extensively in scientific research due to their ability to regenerate limbs. Axolotls were also sold as food in Mexican markets and were a staple in the Aztec diet.

Surveys in 1998, 2003 and 2008 found 6,000, 1,000 and 100 axolotls per square kilometer in its Lake Xochimilco habitat, respectively. A four-month-long search in 2013, however, turned up no surviving individuals in the wild. Just a month later, two wild ones were spotted in a network of canals leading from Xochimilco. The city is currently working on conserving axolotls by building “axolotl shelters” and conserving remaining and potential habitats for the salamanders.

Here’s more info about this fish which is called “Mud Puppy” or “Water Dogs”..

Mudpuppy / Waterdogs the very Strange Looking Fish

The common mudpuppy (Necturus maculosus) is a species of salamander in the genus Necturus. They live an entirely aquatic lifestyle in the eastern part of North America in lakes, rivers, and ponds. They go through paedomorphosis and retain their external gills, thus resembling axolotls. Because skin and lung respiration alone is not sufficient for gas exchange, mudpuppies must rely on external gills as their primary means of gas exchange. They are usually a rusty brown color and can grow to an average length of 33 cm (13 in). Mudpuppies are nocturnal creatures, and only come out during the day if the water in which they live is murky. Their diets consist of almost anything they can get in their mouths, including insects, earthworms, mollusks, and annelids. Once a female mudpuppy reaches sexual maturity, at six years of age, she can lay an average of 60 eggs. In the wild, the average lifespan of a mudpuppy is 11 years. Because of their prevalence and larger size than other salamanders, mudpuppies are good organisms for dissection
