English: Mexican salamanders, or axolotls, have specific living habits due to their unique biology and habitat requirements:
Aquatic Habitat: They live in freshwater environments such as lakes, ponds, and the canals of the Xochimilco region in Mexico. As adults, they are mostly aquatic.
Dietary Needs: Axolotls are carnivorous and consume a variety of prey, including insects, worms, small fish, and crustaceans. In captivity, they can be fed specially formulated food, worms, and sometimes small pieces of fish.
Temperature Sensitivity: They prefer cooler water temperatures, ideally between 16°C to 25°C (60°F to 77°F). High temperatures can stress them out or even lead to death.
Low Oxygen Tolerance: They are adapted to low-oxygen environments and can breathe air through their skin and gills, making them less dependent on high water oxygen levels.
Reproduction: Axolotls reproduce by external fertilization. The female lays her eggs, often attached to aquatic plants, and the male fertilizes them externally.
Metamorphosis: Unlike most amphibians, axolotls usually do not undergo metamorphosis and retain their larval characteristics throughout their lives. However, some may develop lungs and limbs if environmental conditions trigger the change.
Activity Levels: They are nocturnal creatures, meaning they are more active during the night and rest during the day.
Social Behavior: They can be kept in groups in captivity but should have enough space to avoid overcrowding, which can lead to aggression and stress.
Regenerative Powers: Axolotls are known for their ability to regenerate lost body parts, which is a fascinating aspect of their biology.
Chinese: 墨西哥蝾螈或美西螈有一些特定的生活习性,这些习性是由于它们独特的生物学特性和栖息地需求所决定的:
水生栖息地:它们生活在淡水环境中,如湖泊、池塘以及墨西哥索奇米尔科地区的运河。成年后,它们主要生活在水中。
饮食需求:蝾螈是食肉动物,以昆虫、蠕虫、小鱼和甲壳类动物为食。在人工饲养环境中,可以给它们喂食专门的饲料、蠕虫,有时也可以喂小片鱼肉。
温度敏感性:它们喜欢较凉爽的水温,理想温度在16°C到25°C(60°F到77°F)之间。高温可能会使它们感到压力,甚至导致死亡。
低氧耐受性:它们适应低氧环境,可以通过皮肤和鳃呼吸空气,因此对高水氧水平的依赖较低。
繁殖:蝾螈通过体外受精繁殖。雌性产卵,通常会将卵附着在水生植物上,然后雄性在体外进行受精。
变态:与大多数两栖动物不同,蝾螈通常不会经历变态过程,它们的幼体特征会持续终生。然而,如果环境条件触发变化,有些蝾螈可能会发展出肺和四肢。
活动水平:它们是夜行性动物,意味着它们在夜间更活跃,而在白天休息。
社会行为:它们可以在人工饲养环境中成群生活,但应该有足够的空间以避免拥挤,拥挤可能会导致攻击性和压力。
再生能力:蝾螈以其失去身体部位的再生能力而闻名,这是它们生物学中一个非常迷人的方面。
