He was appointed Member of the Order of the British Empire (MBE) in the 2020 Birthday Honours for services to higher education, zoology, reptile conservation and snakebite research.

He has also contributed chapters to books on subjects ranging from rainforest ecology to snakebite, and written numerous popular and scientific articles.

In September 2018 O'Shea was appointed Professor of Herpetology at the University of Wolverhampton.

In September 2002 O'Shea received an honorary Doctor of Science degree from the University of Wolverhampton, for "services to herpetology".

Originally from Wolverhampton, Mark O'Shea moved to Shropshire in 2001. Since 1980, O'Shea has conducted herpetological fieldwork in over 30 countries on six continents but he has special interest in the Australo-Papuan region. He has worked in Papua New Guinea since 1986 when he first visited the country as a member of the scientific directing staff of Operation Raleigh. He continued fieldwork in the country as a member of the Oxford University Nuffield Department of Clinical Medicine snakebite research team throughout the 1990s, and now researches there under the auspices of a fellowship from the Australian Venom Research Unit (AVRU), based in the Department of Pharmacology at the University of Melbourne. In 2006 O'Shea designed a set of six postage stamps called "The Dangerous Snakes of Papua New Guinea", for Post PNG. The launch of these stamps coincided with the snakebite workshops and fieldwork O'Shea and his colleagues from AVRU were conducting in that country.

O'Shea is a Fellow of the Royal Geographical Society and The Explorers Club of New York. In November 2000 he received the Millennium Award for Services to Exploration (Zoology) from the British Chapter of The Explorers Club. The other recipients were Brian Jones (Aerospace), F. Story Musgrave (Artists), Michael Wood (History), Sylvia Earle (Marine Sciences), Sir Chris Bonington (Mountaineering), Buzz Aldrin (Outer Space), and Sir Ranulph Fiennes (Navigation).

O'Shea's Big Adventure, or OBA, known as O'Shea's Dangerous Reptiles on Channel 4 in the UK, chronicles his many field excursions to find reptiles around the world. The programs were divided into four series, The Americas, Australasia & Pacific, South & Southeast Asia and Africa & South America. The first two series each contained 13 half-hour films, the latter two each comprised four one-hour films. They were filmed between 1999 and 2003 and have been aired worldwide.

In 1997 and 1998, respectively, O'Shea made two films: Giant Snake in Venezuela and Black Mamba in South Africa.

O'Shea held the position of Curator of Reptiles at the West Midland Safari Park from 1987 until 2002 when he became Consultant Curator of Reptiles. In 2012, he was bitten by a king cobra while feeding it at the safari park. He had to be treated in hospital after becoming dizzy and unable to speak.

He was Chairman of the International Herpetological Society (IHS) from 1983–86 and its President from 2003–06. In July 2010 the IHS awarded O'Shea with a life membership and fellowship for his "contributions to the Society and herpetology in general".
