Many interesting reptiles and amphibians live in Florida. One of the most famous is the American alligator, which can grow up to 17 feet. Alligators can often be found sunning themselves on riverbanks, and the University of Florida uses a gator as its mascot. The state's reptiles include other dangerous animals, like the beautiful and venomous coral snake. During summer nights, visitors can hear the mating calls of grass frogs and oak toads.
Florida is home to many species of mammals, although they are not as abundant as they once were. Large predatory cats, such as the bobcat and Florida panther, roam the state's vast swamps. Black bears and white tail deer are rarer today but still present in the state. Drivers at night must be alert for opossums, raccoons and armadillos along side the road. The aquatic manatee, or sea cow, lives along Florida's coastline and has been the focus of conservation efforts.
Birding is a popular activity in Florida's parks. Many parks have trails and observation points designed for bird watching. Well-known birds, such as pelicans, roseate spoonbills, ospreys and bald eagles, make their homes in the state. Large turkey vultures are a common sight on trees and power-lines along Florida's highways. Many colorful birds, including cardinals, woodpeckers and blue-jays, migrate south in the winter months and can be seen in backyards across the state.
Florida's warm oceans allow visitors to see a wide variety of undersea life by diving, snorkeling or taking a glass-bottom boat tour. The keys south of Florida have miles of beautiful coral reefs teeming with fish and crustaceans, including barracuda, trumpetfish and sea urchins. Many sport fishermen come to the state seeking to catch sailfish, tarpon and cobia. Florida's beaches host to thousands of visitors each year seeking the seashells left behind by ocean creatures.
