do salamander species also has other species except ambystoma

Absolutely, salamanders are a diverse group known as Urodela or Caudata and include far more genera and species than just Ambystoma. Here are some other notable groups and genera aside from Ambystoma:

1. Plethodontidae (plethodontid salamanders):

   • Plethodon (woodland salamanders)
   • Desmognathus (commonly known as dusky salamanders)
   • Ensatina (Ensatina complex of species with different sub-species across the west coast of the United States)

2. Salamandridae (true salamanders or fire salamanders):

   • Salamandra (commonly known as fire salamanders)
   • Mertensiella (amber salamanders)
   • Chioglossa (Alpine salamanders)
   • Salamandrina (Os穗-Wicken's salamander: native to Japan)

3. Hynobiidae:

   • Hynobius (long-tailed salamanders, from eastern Asia)
   • Lissotriton (crested newts found across Europe)
   • Necturus (only one extant species, the hellbender)

4. Proteidae:

   • Necturus (Aquatic, large salamanders with external gills that live in the southeastern United States)
   • Proteus (the Olm, an unusual cave-dwelling salamander found in Europe)

5. Ambystomatidae (includes Ambystoma and several mole salamanders):

   • Dicamptodon (torrent salamanders, distributed across the western United States and Mexico)

6. Siriobatrachia (Asian salamanders):

   • Euproctus (also known as Alpine salamanders)
   • Tylototriton (Asian worm salamnders)
   • Laotriton

The classification and understanding of salamander species, like many areas of taxonomy, can change over time as research improves our understanding of their genetic relationships.

Many of these salamander species have unique features and environmental adaptations; their existence highlights the diverse evolutionary paths that have led to the present-day amphibian fauna. Protection and conservation efforts for these species vary widely, with some being well-studied and protected while others may need immediate attention to secure their future existence.
