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。
