Shark Cage Diving, Gansbaai, Western Cape, South Africa
So I'm taking credit for one of my wife's photos here. I'm actually in the cage, and that's a hungry Great White Shark! Strange that those other fish are sticking around.
Silvertip Shark, S.E.A. Aquarium, Singapore
The Silvertip is an apex predator whose diet includes other sharks and rays. Unfortunately, it is now an officially "near-threatened" species due to zealous fishermen and the market's demand for shark meat and fins.
Shark Tank From Below, S.E.A. Aquarium, Singapore
The S.E.A. Aquarium in Singapore is definitely one of the best I've ever seen. To be able to look up through a giant skylight and see sharks overhead was one of my highlights. In this shot you can see an endangered Scalloped Hammerhead Shark.
