From discovery.com: One-Horned ‘Unicorn’ Deer Born in Italy.

A deer with a single horn in the center of its head — much like the fabled, mythical unicorn — has been spotted in a nature preserve in Italy, park officials said Wednesday.

"This is fantasy becoming reality," Gilberto Tozzi, director of the Center of Natural Sciences in Prato, said. "The unicorn has always been a mythological animal."

The one-year-old Roe Deer — nicknamed "Unicorn" — was born in captivity in the research center’s park in the Tuscan town of Prato, near Florence, Tozzi said.

He is believed to have been born with a genetic flaw; his twin has two horns.

Calling it the first time he has seen such a case, Tozzi said such anomalies among deer may have inspired the myth of the unicorn. [continue, see photo]
