Hello, I’m Mark O’Shea and I want to thank you for visiting my NEW Official website.

Expeditions, Expeditions, Expeditions, but this new website encompasses much more than the original O'Shea's Big Adventure website. Expeditions are the main-stay of this website. In total I have been fortunate enough to have participated in over 50 expeditions and film trips, to around 40 countries, on six continents, since the early 1980s.

Not only does this site include all my Expeditions since the end of O'Shea's Big Adventure in 2003, it also includes individual accounts for OBA Season 4, which is not represented on the original website. It is planned to expand and improve Seasons 1-3 here also, and include the Pre-OBA expeditions from 1980-1997, as time permits.

The website also includes sections for Herpetology, Photography, Publications, Mark O'Shea's Reptile World @ WMSP, Media & Public, with new and electic sub-sections being added frequently.

I have been intrigued by snakes and other reptiles since I was a child and I kept my first snake at the age of eight. Now, almost 5 decades after snakes first attracted my attention I am still fascinated by the world of reptiles and it would be fair to say that the study of these amazing creatures had dominated almost half a century for me.

So through this website I hope to share that fascination with you, but I am getting ahead of myself, perhaps I should first provide a short biography to explain what set me on the path to becoming an herpetologist.

When you return from there, be aware this website already contains over 1,000 individual pages and thousands of photographs, if you venture in further, don't get lost!
