Key Identification Features
- The most recognizable feature that sets marsh rabbits apart from swamp rabbits and cottontails is that the underside of the tail is almost never white, and is instead usually brownish gray.
- This species has distinctive large grey ears with black tips; the inner ear surface is chestnut brown and white.
- There is a long gap between the incisors and premolars, and the basilar portion of the occipital bone is distinctly narrow.
- Few reliable features exist to distinguish tolai hare subspecies, because their original descriptions relied mostly on external characteristics and were based on small sample sizes.
