Scope note:

Members of a genus containing eight species of elongated, robust, and streamlined fishes with a rounded body that tapers to a slender tail base and a forked or crescent-shaped tail. They have red-colored flesh, rather than white. Some species are warm-blooded, able to maintain body temperatures in very cold water. Some species in other genera have names including the word "tuna," although they are not actually tuna.
