what do mexican salamanders look like in appearance

Mexican salamanders, also known as axolotls (Ambystoma mexicanum), are unique among amphibians due to their distinctive appearance. Here's a breakdown of their physical characteristics: 1. **Size**: They can grow up to 12 inches (30 cm) in length. 2. **Coloration**: Axolotls typically have a dark green or brown base color, but they can display a variety of colors and patterns due to the presence of pigment cells. They have a translucent quality to their skin, allowing you to see their internal organs. 3. **Head**: Their head is flat and wide with large eyes that are often black with a yellowish or golden iris. 4. **Gills**: One of the most remarkable features of axolotls is their external gills. These feathery structures are used for respiration and are usually pink or red. 5. **Body**: Their body is stout and somewhat eel-like, with a long tail that makes up about half of their total body length. 6. **Limbs**: Axolotls have four limbs, each ending in four digits. Their limbs are relatively short and wide, adapted for swimming and crawling at the bottom of their aquatic environment. 7. **Skin**: Their skin is smooth and moist, which helps them absorb water and oxygen. 8. **Regeneration**: Axolotls are famous for their ability to regenerate lost body parts, including limbs, spinal cord, heart, and other organs. Their appearance is quite distinctive, and they are often kept as pets or used in scientific research due to their regenerative abilities.
