can you answer my questions in both english and chinese at the same time

Absolutely, here is the information in both English and Chinese: **English:** Mexican salamanders, specifically axolotls (Ambystoma mexicanum), are unique among amphibians for several reasons: 1. **Neoteny**: Axolotls are renowned for their neoteny, which means they retain juvenile features into adulthood, such as external gills. 2. **Size**: They can grow quite large, reaching up to 18 inches (45 cm), which is sizable compared to other salamanders. 3. **Gills**: They keep their larval gills as adults, which most salamanders lose during metamorphosis. 4. **Color Variation**: Axolotls show a variety of natural colors and patterns, including albino forms. 5. **Regenerative Abilities**: They have exceptional regenerative powers, being able to regrow lost limbs and other body parts. 6. **Lifespan**: Their lifespan can extend up to 10-15 years under optimal conditions. 7. **Diet**: They are carnivorous and consume various small aquatic animals. 8. **Behavior**: Like many salamanders, they are nocturnal. **Chinese:** 墨西哥蝾螈，尤其是美西螈（Ambystoma mexicanum），作为两栖类动物有其独特之处： 1. **幼态持续**：美西螈因其幼态持续而著称，即它们在成年后仍保留幼年特征，如外鳃。 2. **体型**：它们可以长得相当大，可达18英寸（45厘米），与其他螈类相比体型较大。 3. **鳃**：它们在成年后仍保留幼体鳃，这是大多数螈类在变态过程中失去的特征。 4. **色彩变化**：美西螈表现出多种自然颜色和图案，包括白化体。 5. **再生能力**：它们具有非凡的再生能力，能够重新长出丢失的四肢等身体部位。 6. **寿命**：在最佳条件下，它们的寿命可延长至10-15年。 7. **饮食**：它们是食肉动物，以各种小型水生动物为食。 8. **行为**：和许多其他螈类一样，它们是夜行性的。
