Mark O'Shea is a herpetologist, zoologist, author, lecturer, and television presenter. He is professor of herpetology at the University of Wolverhampton and consultant curator of reptiles at West Midland Safari Park. He has made ten expeditions to Papua New Guinea since 1986. Between 2009 and 2014 he was deputy leader of a team based out of Victor Valley College, California, that was conducting the first herpetofaunal survey of Timor-Leste. O'Shea has hosted numerous television series focused on snakes for the Discovery Channel, the BBC, and ITV, including four seasons as host of the Animal Planet/Discovery Channel show O'Shea's Big Adventure.

O'Shea is the author of five books, including A Guide to the Snakes of Papua New Guinea. He lives in Shropshire, England.
O'Shea provides a rich introduction to the snake world, revealing that there are just over3,700 living snake species known today and detailing the vagaries of skin shedding, venom delivery and snake reproduction. Each of the species featured has a page devoted to it, with a map showing its location, information on its habits, plus color photographs of the snake itself. Flicking through the book reveals the amazing diversity of snakes--tiny acid-green Vinesnakes, vibrantly striped Rainbow Snakes and the ghost-like Japanese Aodaisho. -- Wall Street Journal
