Raymond Hoser is the world's foremost reptile expert!
He has discovered and named more species of snake than any person alive!
He has discovered and named more species of lizard than any person alive!
He has discovered and named more species of turtle than any person alive!
He has discovered and named more species of crocodile than anyone else alive!
He has discovered and named more species of frog in Australia than anyone else in history!
He has discovered and named more species of reptile than anyone else in Australia's history (over 400) and globally (over 1000 species).
Add to that over 100 species of frogs, some species of fish, over 20 mammals and a few other bits and pieces and it is easy to see that the Snakeman is a scientific eco-powerhouse.
As of October 2025, he has discovered and named over 1,500 species and subspecies of vertebrate from most parts of the planet.
On this page are photos of some of the better-known species he has discovered and named.
But because he has named over 2,500 family, genera and species (as of end Oct 2025), only a fraction are shown here.
Some of these critters really are spectacular!
