## Salamanders

| Name | Species/Authority | Order | Family | Range and status | IUCN Red List |
| Common mudpuppy | Necturus maculosus | Salamander | Proteidae | Common; Introduced to the Connecticut River in 1936; However, there are records from the Connecticut River in Connecticut as early as 1875; The mudpuppy has also been reported from lakes in Berkshire County which probably means it is native to Western Massachusetts | 7 |
| Jefferson salamander | Ambystoma jeffersonianum | Salamander | Ambystomatidae | Uncommon; Found mainly throughout Western Massachusetts; This amphibians range includes the blue spotted/Jefferson salamander hybrid, where both species interbreed and creates hybrids; It is a species of special concern in the Commonwealth due to habitat loss | 7 |
| Blue-spotted salamander | Ambystoma laterale | Salamander | Ambystomatidae | Uncommon; Reported from Bristol County, Essex County, Middlesex County, Eastern Worcester County, and Norfolk County; Distinguished from most salamanders by its blue spots; Reports of Western Worcester county may represent the Jefferson salamander; Listed as special concern due to habitat loss | 7 |
| Spotted salamander | Ambystoma maculatum | Salamander | Ambystomatidae | Common; Statewide except Nantucket | 7 |
| Marbled salamander | Ambystoma opacum | Salamander | Ambystomatidae | Rare; Statewide except Cape Cod, Nantucket, and Dukes County; Threatened in the Commonwealth; There are old records from Plymouth and Essex counties; This species is difficult to locate, making it rare; The fact that Massachusetts is its almost northernmost limit of its range (it is also found in southern New Hampshire) makes it clear why its rare in the state | 7 |
