Mammals are “endothermic” or “warm-blooded” animals. The majority of mammals have an insulating layer of fur that allows them to maintain a near-constant body temperature. Just about all mammals have live birth rather than hatching from eggs.

  • White-tailed Deer


    Florida deer are considerably smaller than those in most other states. Deer in Florida are well adapted to the climate and environment. The smaller body size is beneficial in warm climates because it allows for less energy to be expended for regulating body temperature. Smaller body sizes also may enhance survival in habitats where soil fertility is low. There are four subspecies of white-tailed deer in Florida.

  • Bobcat


    Bobcats are elusive and nocturnal and therefore rarely spotted by humans. Although they are seldom seen, bobcats have been spotted throughout the year at various spots along the refuge's trails.

  • River Otter


    The North American river otter (Lutra canadensis) is a semi-aquatic weasel that prefers the fresh water habitats of rivers, lakes, creeks, streams, swamps and coastal areas. Like other members of the weasel family, river otters have slender bodies with short limbs and faces. They feed on crayfish, crabs, fish, birds, small mammals and aquatic plants. Their oily water proof coats and webbed toes make them well adapted for their wet environment and they can remain underwater for up to eight minutes. While the historic range of the North American River Otter extended throughout the United States and Canada, river otters have disappeared from areas of the middle and eastern United States. Excluding the Keys, river otters are found throughout Florida.

  • Raccoon


    Raccoons (Procyon lotor) are a medium-sized mammal common in tree-habitats throughout Florida and the United States. They are easily identified by a black mask and ringed tail. Raccoons are opportunistic omnivores and will feed on a variety of foods based on availability. This includes fruit, small mammals, plant material, crustaceans, eggs and even garbage. Although common and often considered a nuisance in urban areas where they have lost the fear of humans, raccoons are wild animals and should be treated as such.

  • Round Tailed Muskrat

    Round tailed muskrats (Neofiber alleni) are nocturnal rodents that are most active after dusk. The majority of their diet consists of stems from aquatic grasses. They prefer water depths of 12-18 inches and build their homes near the surface of the water with underwater entrances. Round tailed muskrats have been found in dense populations within the Florida Everglades but their range extends throughout most of peninsular Florida and into the south-central and southeastern part of Georgia. They are prey for bobcats, snakes and birds.

  • Marsh Rabbit

    Marsh rabbits (Sylvilagus palustris) are excellent swimmers that occupy undisturbed marsh habitats in the coastal plain of the southeastern United States. They prefer freshwater but will occupy salt and brackish marsh areas as well. Although marsh rabbits are approximately the same size as cottontail rabbits, their legs and ears are shorter and, with less hair than a cottontail, they appear smaller. Marsh rabbits are the only members of the family Sulvilagus that do not have a white area on the underside of their tail. Their predators include great horned owls, northern harrier hawks, bobcats, alligators, rattlesnakes and cotton mouths. In more recent years, marsh rabbits have a new predator in the Everglades ecosystem, the highly aggressive Burmese python.
