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 the world for a sub-species of cougar known as the Florida panther. This large, beautiful cat is on the [endangered] species list. Today many groups and individuals are working to keep this [predator] a part of the [environment]. Their efforts have resulted in methods to assist panther recovery: lower speed limits and highway culverts and bridges, to mention only two. With continued assistance, the panther may remain a part of the [Everglades] for years to come.
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 (sometimes 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 often found well north of the park on both coasts in cold weather, when they swim up rivers to seek the constant-temperature water discharged by electric power plants. Despite its size, the manatee is a harmless creature, being a grazer—a sort of underwater cow that is exceptionally vulnerable to motorboats because of its gentle nature and languid movement.
