The smaller but stockier Bull Shark (Carcharhinus [Lamnarius] leucas) is another dangerous species, most famous for its ability to penetrate far up freshwater rivers. It has been captured in freshwater rivers and lakes in Australia, New Guinea, the Philippines, Asia, Africa (where it has been known to attack young hippos), North, Central, and South America. Tagging studies in the 1960's and 1970's by Thomas Thorson and his co-workers have revealed that the Bull Shark readily swims between the Caribbean and Lake Nicaragua via the Rio San Juan, despite the churning rapids that were thought impassable and the tremendous osmotic changes between saltwater and fresh. Bull Sharks have also been captured off Alton, Illinois, 2,360 miles (3,800 kilometres) up the Mississippi River and in the foothills of the Peruvian Andes (surely one of the last places on Earth one would expect to find a shark), some 2,610 miles (4,200 kilometres) up the Amazon River.


No more diving in the Mississippi for me.

I saw them at the Aquarium in Denver - nice thick glass between them and me. That is as close as I care to get.

You know, as a general rule, sharks are an added bonus, not the point of the dive. That being said, I've seen some pretty cool sharks and had some pretty cool sitings.

My big three regrets sharkwize are:

1. Almost missed a night dive because of Tiger Sharks in the area. Dive went on anyway and since I took the risk, I'm a little disappointed I didn't get to see one.
2. I have a friend with land in South Africa. He has invited me down for a cage Great White dive. I keep meaning to take him up on it but haven't yet.
3. I've been in Hammerhead Territory at peak times but have yet to encounter one.

Actually, I saw this on a web site when I was looking for information about a specific kind of shark, not the Bull Shark. But with that being said, I do have to mention I was in the water with a Bull Shark last June down in Destin. I admit I was kind of nervous about it, but once I was back on the boat, it really hit me what I saw. Pretty cool.

Chris just got back from Australia today. I saw him briefly at the shop. He said he has about 6 hours of video from the Great Barrier over there. He also went nose to nose with a Whaler Shark. (Dont make the same mistake I did and think it was a Whale Shark.) Whaler Shark is what I was looking up when I came across the story above.
