Florida river dolphin (Isthminia Mississippiensis) is a species of river dolphin native throughout the southeastern United States. It is about the size of the Amazon river dolphin, but is slightly more designed to swim in higher speeds. It is a carnivore that mainly feeds on fish, crustaceans, mollusks, frogs, small reptiles, birds, small-to-medium-sized mammals, eggs, and carrion, although they also can adapt to feed on man-made food for humans as well as domestic animals/pets such as dogs, cats, rodents, rabbits, birds, and fish. It is a social pod-dwelling mammal that lives in groups up to about 19, depending on an area it lives in. The conservation status of the Florida river dolphin is Least Concern due to successful conservation efforts, being able to adapt to polluted waterways (after tolerating higher and higher amounts of man-made pollutants over time), and being able to adapt to captive life, both in zoo/safari park/aquarium parks and in large tanks.
