美西鈍口螈。這種動物真是丑到一定境界了，不過人家自己一點不擔(dān)心。作為一種"水中小怪獸"，它可以用腿行走。雖然長有肺，它卻偏偏不用，而是通過皮膚呼吸。任性！

He may be as ugly as sin, but the Axolotl (Ambystoma mexicanum) doesn't seem too bothered by it. Roughly translating to 'water monster' the aquatic creature walks on legs and while it does develop lungs, it doesn’t really use them, preferring instead to draw oxygen from its ruff of gills or even from its skin. If its habitat dries up, it can metamorphose into a form that will wander off in search of a new home. [Photo/Agencies]
