General Description
Description
Source and Additional Information
Among the largest terrestrial salamanders. Stout-bodied animals with broad heads and small eyes. Adults have a dark brown to grayish black dorsal color overlain with numerous, large, irregular, dirty brown to brownish yellow spots or vertical streaks. Belly is marked with irregular pale yellow blotches on a darker background. Gilled adults are rare. Hatchlings show paired blotches along the dorsum and an unpigmented venter.
Ambystoma tigrinum once referred to a wide ranging species complex exhibiting tremendous geographic variation in morphology, behaviour, and life history and included as many as eight subspecies. New taxonomical understandings (Irschick & Shaffer 1997) have split this complex up and A. tigrinum is now entirely composed of what was once the subspecies A. tigrinum tigrinum. The other subspecies have been reassigned.
