The animals on the cover of Mastering Oracle SQL, Second Edition are lantern flies. The lantern fly is mostly tropical, with a wingspan of up to six inches. The lantern fly's elongated head is an evolutionary adaptation called automimicry, in which parts of the body are disguised or artifically shifted to other areas to confuse predators: the lantern fly's head looks like a tail, and its tail looks like a head. On the rear it has artificial eyes and antennae.

Matt Hutchinson was the production editor for Mastering Oracle SQL, Second Edition. Octal Publishing, Inc. provided production services. Sarah Sherman, Marlowe Shaeffer, and Colleen Gorman provided quality control.
