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.

Why is keeping axolotls as pets not a good idea?
- A The cost is too high.
- B It is illegal in many countries.

思路引導 VIP
請觀察文章最後一段提到的「人工飼養環境」（captivity）與「野外自然水域」（lakes and lagoons）之間的對比。作者特別提到，在某些特定物理條件的變化速度上，這兩種環境有什麼顯著的差異？而這個差異為何會讓飼主感到非常棘手？

環境適應與溫度的關鍵性
能從文章最後一段精確擷取細節並進行邏輯推論，你的閱讀理解能力非常紮實！這題選 (D) 是完全正確的。文章結尾特別提到，墨西哥蠑螈（axolotls）原生於湖泊與潟湖等靜止水域，這些大自然環境的溫度「不會像人工飼養環境中波動得那麼快」（temperatures tend not to fluctuate as quickly as they can in captivity）。這意味著野外環境的水溫相對穩定，而人工環境（captivity）的溫度控制則是一項艱鉅的任務（serious undertaking），因此飼養牠們並非易事。
