Thats important, because it tell us we still have a chance,\" Garza said. \u003cbr/\u003eThe axolotl is known as the \"water monster\" and the \"Mexican walking fish.\" \u003cbr/\u003eThey are considered important in scientific research, because of the axolotl's ability to 'regenerate' or re-grow severed limbs.\u003cbr/\u003eIt's only natural habitat is the Xochimilco network of lakes and canals.\u003cbr/\u003eThe creature is now suffering from pollution, urban sprawl and invasive species. \u003cbr/\u003eAxolotls use four stubby legs to drag themselves along the bottom or thick tails to swim in Xochimilco's murky channels while feeding on aquatic insects, small fish and crustaceans. \u003cbr/\u003eBut the surrounding garden-islands have increasingly been converted to illicit shantytowns, with untreated sewage often running off into the water.\u003cbr/\u003eGarza said that although pollution is the main factor making it difficult for axolotls  to survive, it's a custom for people living in the Xochimilco Lake region to catch and eat the amphibian.\u003cbr/\u003e\"Since pre-Hispanic times it was a delicacy, they (indigenous people) say it used to be a delicacy of the Gods and later the people of the region ate it almost on a daily basis. Also, it's been used to make a syrup to aid with respiratory issues, so this has created a very complicated situation today,\" Garza said.\u003cbr/\u003eSome axolotls still survive in aquariums, water tanks and research labs, but experts said those conditions aren't the best, because of interbreeding and other risks.  \u003cbr/\u003eReleasing captive-bred axolotls into the wild could spread a fungus infection that is fatal to them and could reduce their genetic diversity. \u003cbr/\u003eGarza said some small mutations  possibly the result of interbreeding  have already been seen.\u003cbr/\u003eAlarmed by the creature's falling numbers in recent years, researchers built axolotl \"shelters\" in Xochimilco to help them breed in the cleanest part of their remaining habitat.\u003cbr/\u003eSacks of rocks and reedy plants act as filters around a selected area, and cleaner water is pumped in, to create better conditions. \u003cbr/\u003eThe shelters also include permeable cages and other devices intended to help protect the axolotls from non-native carp and tilapia that were introduced to the lake system years ago and compete with axolotls for food.\u003cbr/\u003eThe Mexican Academy of Sciences said in a statement that a 1998 survey found an average of 6,000 axolotls per square kilometer, a figure that dropped to 1,000 in a 2003 study, and 100 in a 2008 survey.\u003cbr/\u003eMexico City, Mexico-21 February 2014\u003cbr/\u003e1.
