Swamp rabbit

The swamp rabbit (Sylvilagus aquaticus), also called the cane-cutter, is a large cottontail rabbit found in the swamps and wetlands of the southern United States. The species has a strong preference for wet areas, and it will take to the water and swim.[4]

Range and habitat[edit]

The swamp rabbit is found in much of the south-central United States and along the Gulf coast.[5] It is most abundant in Alabama, Mississippi, and Louisiana, but also inhabits South Carolina, Arkansas, Tennessee, Texas, Oklahoma, Missouri, Kentucky, Illinois, Indiana, and Georgia.[5] It is possibly extirpated from Kansas.[6]


Swamp rabbits mainly live close to lowland water, often in cypress swamps, marshland, floodplain, and river tributaries.[5] Swamp rabbits spend much of their time in depressions which they dig in tall grass or leaves, providing cover while they wait until the nighttime to forage.[5]


There is concern that swamp rabbits are increasingly becoming exposed to predation, especially during snowy/wintry seasons. Snow cover has shown to increase swamp rabbit mortality by almost two times in the northern extent of their range. This is due mostly to the fact that snow cover constrains hiding ability and availability of food resources.[7]

Physical description[edit]

S. aquaticus is the largest of the cottontail species, although its ears are smaller than those of other cottontails.[5] Males are slightly larger than females.[5] The head and back are typically dark or rusty brown or black, while the throat, ventral surface, and tail are white, and there is a cinnamon-colored ring around the eye.[5] Their sides, rump, tail and feet are much more brownish, along with a pinkish-cinnamon eye-ring, as opposed to the whitish eye-ring in eastern cottontails.[4]


S. aquaticus males vary in weight from approximately 4 lb (1.8 kg) to 5.6 lb (2.5 kg), with an average of about 5 lb (2.3 kg); females vary from approx. 3.6 lb (1.6 kg) to 5.9 lb (2.7 kg), averaging about 4.8 lb (2.2 kg). S. aquaticus ranges in length from approx. 17.8 inches (45 cm) to 21.7 in (55 cm), with an average length of about 19.7 in (50 cm).[5]

Predation[edit]

Known predators of Sylvilagus aquaticus are domestic dogs (Canis familiaris), American alligators (Alligator mississippiensis), and humans (Homo sapiens).[5] Even though their swimming abilities[8] lack the speed to escape a pack of hunting dogs, swamp rabbits elude pursuers by lying still in the water surrounded by brush or plant debris with only their nose visible.[4] The species is hunted for fur, meat, and sport, and is the second-most commonly hunted rabbit in the United States.[5] Swamp rabbits have several adaptations to avoid predators: cryptic coloration, "freezing", and rapid, irregular jumping patterns.[5]

Diet[edit]

Swamp rabbits are herbivorous; they eat a variety of foraged plants, including grasses, sedges, shrubs, tree bark seedlings, and twigs.[5] They feed mainly at night but rain showers will often cause them to feed during daytime as well.[4] A study has found that the preferred foods of S. aquaticus are savannah panicgrass (Panicum gymnocarpum), false nettle (Boehmeria cylindrica), dewberry (Rubus trivialis) and greenbrier (Smilax bona-nox).[5]


Like all lagomorphs, the swamp rabbit creates, expels & eats cecotropes (cecotrophy) to get more nutrition from its food.[5]

Species competition[edit]

Rival males will often engage in aggressive encounters that sometimes become violent enough to kill one of the combatants. When fighting, males will stand on their hind legs and use their teeth and claws to inflict wounds on their opponent. They will also jump from the ground and strike with the sharp claws of the hind feet.[4]
