Ecology and Behavior

Sharks skates and rays – To maintain balance, the shark’s body is heavier on one end than the other. They use their fins as a stabilizer to stay upright in the water or change direction quickly. Sharks also have two salt-secreting glands behind each eye which helps them fight disease and regulate osmosis. Bony fish – The tuna family of bony fish is “picky eaters” who only feed on planktonic organisms such as crustaceans, snails, small mollusks, and small fish. Fish – A group of several distinct species that have evolved from a common ancestor. Marine Catfish – Ocean perch spend most of their time on the bottom of the ocean, where they eat crustaceans and other invertebrates. Mud Minnows – There are four kinds of mud minnows: creek chubs, hornyhead chubs, redhorses, and yellowfin shiners. Sturgeons – The eastern sturgeon can grow to be about 10 feet long and weigh more than 800 pounds. They swim slowly along the bottom looking for food such as mussels, clams, crabs, and crayfish. They get large by eating rather than by growing fast like many creatures. Flatfish – Flatfish swim near the bottom in shallow inshore waters, reaching depths of 660 feet. They swim on one side with both eyes on top and eat planktonic organisms like krill and small fish. Lungfish – There are six species of lungfishes found in Africa (Nile, Transvaal), South America (Bolivia), and Australia (Callendar River). Armored catfish – The roundness provides protection from predators because their bodies cannot be easily compressed like most other fishes. Tropical Cichlids – Cichlids are particularly interesting because they possess physical features that make them adaptable to many different habitats.
