There is a lot of controversy in the diving world these days about shark feeding for divers. It's even illegal in some places. There is concern about unnecessary danger to the divers and worry that the animals are being conditioned inappropriately.

The way this works is very controlled. And we never felt in any danger. The divemaster takes a "chumsicle" -- basically, a bucket of frozen fish guts, minus the bucket -- and ties it to a line floating above the mooring pin. The divers are led to a line in the sand below the pin in about 45 feet of water. And the action begins.

I've done two now and, although it can be a little cheesy and staged, it can also be a remarkable experience to be in this kind of proximity to the powerful and graceful creatures.

Plus, these feeds can offer a photographer many great opportunities to get dramatic images.

I counted twelve sharks on this dive, all Caribbean Reef sharks. They ranged in size from about three feet to about six feet.
