Known locally as “water monsters,” axolotls have somewhat polarizing looks. For some, they are considered adorable for the appearance of a perpetual smile; for others, these four-toed amphibians are just plain odd. Scientists are particularly interested in axolotls’ ability to regenerate cells and body parts and seeking to apply such a quality to heal injuries, illnesses, or human organs. Some axolotl species transform themselves into earth-walking salamanders by losing their tadpole-like tails and gills from their heads. However, those who never transform into salamanders will keep the tail and live completely underwater. In fact, there is little reason to undergo transformation because they have fewer predators and more food in the water. Because of their nature to change form, axolotls are recognized as a representation of Xolotl, god of the underworld in Aztec culture. Legend has it that when various gods were asked to make a sacrifice to create the world, Xolotl fled into the water. For his cowardice and reluctance to help, he was damned to live forever in the water and denied transcendence into a higher realm. The axolotl, though gaining attraction as a symbol of Mexico City, is nearly extinct in the wild due to water pollution in the city’s troubled canals and increases in invasive fish species which feed on young axolotls. Environmental threats to axolotls include agricultural waste, pollution from industrial fertilizers, as well as non-native plants and fish species such as carp and tilapia, which were introduced by the government to supply food to rural areas. While keeping axolotls as pets around the world is legal, it may not help the species. As they live in still water lakes and lagoons, the temperatures tend not to fluctuate as quickly as they can in captivity, and thus making captivity a serious undertaking.

請你重新掃描文章最後一段中關於『環境威脅』的描述，試著將文中提到的所有因素分類。你可以發現文中主要聚焦於『人類活動導致的污染』以及『生物入侵』，那麼，是否有任何文字提到了關於『自然降雨減少』或『缺水問題』的具體描述呢？

恭喜你答對了！這代表你在閱讀長篇文章時，具備非常敏銳的資訊檢索與比對能力。這道題目要求找出「非」滅絕原因，是典型的細節辨析題，考驗的是我們能否在眾多干擾資訊中，精確地排除文章未提及的選項。
棲地威脅的關鍵因素
在文章最後一段中，作者詳列了墨西哥鈍口螈（美西螈）面臨的生存威脅。文中明確提到水污染（water pollution）、農業廢棄物（agricultural waste）以及工業化學肥料（industrial fertilizers），這對應了選項 (A)、(B)、(C)；同時，文中也提到了**外來入侵魚種（invasive fish species）**如鯉魚與吳郭魚，這對應了選項 (E) 的 exotic species（外來種）。
