Hello, everyone, and thanks to the Shark Diver for the wonderful introduction!
As a marine biologist, I will try to provide a scientific perspective on the shark world. As stated in my introduction, though, I am also an ardent conservationist and a SCUBA diver, so there is very little in the shark world that I won't comment on. My specific research deals with the food chain relationships of the sandbar shark along the Southeastern United States, and I've worked in the past on the electrosensory system of small Outer Banks stingrays.
I'll post something more substantial in the coming days, but I wanted to alert the shark diving industry crowd to an ethical debate taking place on my other blog (Southern Fried Science). It deals with the ethics of shark diving itself. Please find it here, and check the blog often!
Thanks, everyone, and I look forward to many interesting discussions about sharks in the future.
