Wow, this shows that Australia has as many shark species as several oceans combined! Haha, what a cool place. https://www.shark.ch/Database/Distribution/index.

Haha, what a cool place. https://www.shark.ch/Database/Distribution/index.html https://www.shark.ch/Database/Distribution/index.html You're right though, warmer waters tend to have more species. I'm not able to find anything indicating actual numbers of sharks, but more species (correct me if I'm wrong) seems to indicate a larger cumulative population and more and/or more diverse prey In another life I'd love to be a marine biologist. There's so much to know and understand better.
