The Ender Dragon does not classify as a bird or a fish. It is hypothesized to align more closely with reptiles, supported by the existence of reptiles commonly referred to as "dragons," such as the bearded dragon and the komodo dragon. The scientific community recognizes a family of lizards known as Agamidae, which includes 582 species often called dragons. The Ender Dragon has not exhibited swimming behavior, further dismissing its classification as a fish.
