Advanced Search Search Forum Welcome! This web site is devoted to the Axolotl pronounced Ax-oh-lot-ulscientific name Ambystoma mexicanum. The site describes the Axolotl's background, biology, and care in captivity. You will also find information about the Tiger SalamanderAmbystoma tigrinum and Ambystoma mavortium spp.
Because it's a salamander, it's part of one of the three branches of class Amphibia, which also includes the frogs and toads the Anuransand the mainly eel-like order, Gymnophiona, which are also known as the Caecilians.
Have a look at the Biology Page for a short guide to the Axolotl's body and characteristics. One common misconception is that axolotls and other salamanders are lizards or reptiles.
In fact, amphibians are Harlequin case study completely Harlequin case study group of animals. For example, did you know that reptiles and human beings have a four-chambered heart? Well amphibians have only three chambers. That's just one example of how appearance can be deceiving: This page is a brief introduction for those new to the Axolotl and salamanders.
If you require specific information, you can search this site using the search facility at the top right of this page. There is a very busy axolotl forum at Caudata. I hope that you find this site useful, but most of all I hope you enjoy what you read and find here.
If you're looking for information about metamorphosed axolotls, click here. Axolotls of various colours occur in captivity, including grey, shades of brown, leucistic white with black eyesgolden albino, white albino, as well as other varieties, such as the melanoid a near-black animal.
The normally coloured axolotl, the "wild type", can be near-black like the one in the group photo to the left, chocolate brown like the one in the site's logo, or even creamy in colour, and anywhere in between. There are even "piebald" axolotls in various coloursand a variety that is piebald in more than one colour, known as the "harlequin".
You can learn more about how colour comes about and how it is passed on by taking a look at the Genetics Page.
And why not take a look at the hundreds of photos of the weird and wonderful varieties of axolotls submitted by enthusiasts like yourself at the Axolotl Section of the Caudata. The name "Axolotl" comes from the Aztec language, "Nahuatl".
One of the most popular translations of the name connects the Axolotl to the god of deformations and death, Xolotl, while the most commonly accepted translation is "water-dog" from "atl" for water, and "xolotl", which can also mean dog.
Of these two high altitude freshwater lakes, only the remnants of Xochimilco as canals can be seen today. Unfortunately many information sources mention these lakes as if they still exist such as this ill-researched article about a metamorphosed axolotl on the BBC News Web site.
If only this were still the case: There have been efforts to breed and release the animal, in order to re-establish its numbers. However the location of the remaining waterways where the animal may live located in the Mexico City metropolitan area are likely to be very threatened by the city's continuing expansion and the days of the species surviving in the wild are surely quite limited.
Fortunately, due to the importance of the Axolotl in scientific research, it is unheard of for them to be taken from the wild for that purpose because of the huge numbers bred in captivity each year.
There are related Mexican Ambystoma species that also remain gilled as adults. These species are located in water bodies further from Mexico city and may have a slightly brighter future in the wild than the Axolotl.
Despite its endangered status, the use of the Axolotl as a laboratory animal should ensure the species' survival, if only in captivity. It has long been known that the Axolotl is a worthy study due to its amazing healing and regeneration abilities. Normal wound healing in animals occurs through the growth of scar tissue, which is not the same as the original tissue, nor is it as robust.
Normal wound healing also does not allow for most animals to re-grow a lost limb.Transcript of Harlequin Strategy Case Should Harlequin try to sell single title books? Harlequin Enterprises: The MIRA Decision Recommendations S W O T Problem Barriers to Entry.
