One of the most exciting things we did on our Hawaii vacation was to dive with sharks. We went to the North Shore and took a small little boat out to "shark infested waters." We jumped into a little cage with snorkel masks and watched intensely as raw meat was tossed into the water for the sharks to gobble up. The longer we were in the water, the more curious the sharks seemed to be and they would swim right up to the cage and look at us. It was a pretty thrilling experience to have sharks swimming under and around us!
We saw about 4 of these sandbar sharks. These sharks are about 7 feet in length. (This is a picture from the dive website.)
We saw a couple of galapagos sharks. They are described as aggresive and dangerous. They can grow to be 10 feet long.
The pictures we took above the water just don't do these animals justice! If I went again, I would buy an underwater camera.
Side Note: Gabe also got to scuba diving during our trip. He loved it! He went to two separate dive sites and got his Nitrox certificaiton.
