i think the word ambystoma means a salamander species

Yes, you're correct! The term "ambystoma" refers to the genus of salamanders that includes several species commonly known as mole salamanders. These salamanders are characterized by their rounded snout and lack of external gills or hind toes compared to other salamander species. Here are some key aspects about Ambystoma species:

1. Number of Species: The genus Ambystoma consists of around a dozen species, native primarily to North America. Some species are quite distinct in terms of habitat, appearance, and behavior.

2. Taxonomy: Within this genus, you'll find the Mexican axolotl (Ambystoma mexicanum) which, as discussed, is famous for its unique neoteny (maintenance of juvenile features into adulthood) and regenerative abilities.

3. Habitat Variety: Different Ambystoma species occupy diverse environments, from aquatic habitats like ponds and lakes to terrestrial settings such as moist woodlands. Some species exhibit complex life cycles, alternating between aquatic larvae with external gills and land-dwelling adults.

4. Behavioral Patterns: Most Ambystoma species are nocturnal or crepuscular and tend to be quite secretive, coming out at night to feed or hide during the day in damp crevices. Their diet typically consists of various small invertebrates like insects, worms, and even other amphibians.

Some of the notable species within the Ambystoma genus include:

• A. tigrinum – Tiger salamander
• A. opacum – Midget fissured salamander
• A. texanum – Northern blunt-tailed salamander
• A. jeffersonianum – Jefferson salamander

Each has distinct characteristics and ecological roles, which underline the fascinating biodiversity within the salamander family.
