The bat is the primary animal-representation for Dracula. Bats in the novel, of course, desire the blood of other living things—they are mammals, and certain species of vampire bat do indeed feed on living animals. The bat, also, is nocturnal, or active at night, and the bat can fly, allowing it access to places Dracula might not otherwise be able to reach. Morris attempts to shoot a bat he sees flying around a meeting of the group, at the insane asylum; Harker fears that Dracula has changed himself into a bat, at his castle; both Lucy and Mina report having seen bats near them when they are being attacked by Dracula (or having their blood sucked); and Van Helsing later informs the group that bats—and also, secondarily, wolves and rats—are creatures historically associated with vampires, or the Un-Dead. When Dracula is truly killed at the end of the novel—when his spirit is "set free" by the group—representations of bats also cease—the bats are no longer under Dracula's power, and are free to return to their normal lives in the wild.
