Bestiality

Bestiality is sexual relations between a human being and an animal of another species. (The term zoophilia is used for sexual attraction to animals.)

Bestiality has been condemned as unnatural and as constituting [animal abuse]?. Others such as Peter Singer argue that this is not inherently the case. Bestiality is illegal in many jurisdictions, while in others, such as in Germany, mistreatment of animals in general is outlawed but bestiality is not specifically mentioned.

Although rare in practice, bestiality has been less so as a subject in art, literature, and fantasy. In Greek mythology, Zeus appeared to Leda in the form of a swan? (resulting in the birth of Helen of Troy and Pollux?), and the Minotaur was the offspring of Queen Pasiphae and a white bull.
