DISCOVERING EVERGLADES PLANTS AND ANIMALS (continued)

Mammals

In the drowned habitats of Everglades it is not surprising to find water-bound mammals such as the porpoise; or fish-eating amphibious mammals such as the otter; or even land mammals, such as the raccoon, that characteristically feed upon aquatic life. But to see mammals that one ordinarily does not associate with water behaving as though they were born to it is another matter. The white-tailed deer is an example. It is so much a part of this watery environment that you will most likely observe it far out in the glades, feeding upon aquatic plants or bounding over the marsh. Very probably the deer you see was born on one of the tree islands, and has never been out of sight of the sawgrass river.

Many other mammals of Everglades are adapted to a semi-aquatic existence. The park's only representative of the hare-and-rabbit clan is the marsh rabbit; smaller than its close relative, the familiar cottontail of fields and woodlands, it is as comfortable in this wet world as if it had webbed feet. So don't be startled if you see a rabbit swimming here! The park's rodents include the marsh rice rat and round-tailed muskrat, also at home in a watery environment.

The playful otter, though it may travel long distances overland, is a famous water-lover. Lucky is the visitor who sees a family of these large relatives of the weasel! The otter's smaller cousin, the everglades mink, is also a denizen of the marsh and a predator in the food web; but you are not likely to see this wary animal.

Raccoons and opossums, adaptable creatures that they are, live in all the park's environments—except in the air and under water. Their diets are as wide-ranging as their habitat. The raccoon, though it has a taste for aquatic animals such as fish, frogs, and crayfish, also consumes small land vertebrates and various plant foods. The opossum eats virtually anything in the animal kingdom that it can find and subdue, as well as a wide variety of plant materials.

South Florida is the last known refuge in Eastern United States for the cougar—known in this region as the Florida panther and in the west as the mountain lion. This big, beautiful predatory cat formerly ranged over most of North America. Today it is at home in many of the park environments, and despite limited numbers plays a role in maintaining the balance between the plantlife of the park and plant eaters such as the deer upon which it preys.

Because it is much more numerous and much less secretive in its habits, the bobcat is more likely to be encountered by park visitors than is the cougar. Keep your eyes alert for this wild feline—particularly in the Flamingo area—and you may have a chance to observe it closely and at some length (even by daylight!). Such boldness and such unconcern for humans are not typical of this species, but seem to be peculiarities of the bobcats living in the park. Although bobcats are not known as water lovers, they are found in all the Everglades environments. Their apparent liking for life in the park may be due to an abundance of food and to freedom from persecution by man and his dogs. Bobcats in Everglades, if their food habits elsewhere are any guide, probably live on rodents, marsh rabbits, and birds, with possibly an occasional fawn.

In Florida Bay and the estuaries, look for the porpoise, or bottlenosed dolphin, a small member of the whale order that has endeared itself to Americans through its antics at marine aquariums and on television. Watch for it when you are on a boat trip in the park's marine environment.

Much less commonly seen, and much less familiar, is the timid and very rare manatee. It's probably the "most" animal of the park—the largest (some times over 15 feet long and weighing nearly 1 ton), the shyest, the strangest, and the homeliest; and it is probably also the most delicate, for a drop in water temperatures may kill it. The estuaries of Everglades National Park are almost the northern limits of its normal range. But manatees are sometimes found well north of the park on both coasts in cold weather, when they swim up rivers to seek the constant-temperature water of some of the big springs. Despite its size, the manatee is a harmless creature, being a grazer—a sort of underwater cow. But because of man's motorboats and his guns, the park is the last haven for the manatee.
