It happened to me ... twice. Each time I was grabbed from behind by the BC or tank. I have a theory about a diver who went missing at Tiger Beach. It's all in my book about shark diving which is available on Amazon.
 
Just goes to show... never wear yellow tanks or yellow fins
 
Few comments here. Never turn your back on a predator (Except for a Grizzly, play dead) its not called yummy yellow for no reason. I bet it is the same shark from the December attack.
 
Rangers will not kill the shark nor approve such an action (at least for now)...they were already asked. A few other aggressive incidents in Cocos since the women who was killed, but no "bites"...just not reported here. So glad there was not an injury or worse.

Uh, no. You were right at first. Playing dead has been determined as ineffective. Don't even turn your back on a threatening bull or cow (bovines) and they're herbivores.
 
LOL,,,You've been diving a very long time and know better than that.

List of Animals That See in Black & White
Fish and Marine Mammals
Most marine mammals are monochromatic; this includes pinnipeds, such as seals, sea lions and walruses, and cetaceans, such as dolphins and whales. Most fish are trichromatic, with good color vision, but there are some exceptions. The only animals known to have no cones at all, and therefore that are incapable of color vision, are skates, cartilaginous fishes related to rays and, more distantly, to sharks. Sharks are also monochromatic, but rays are thought to have relatively good color vision. Marine mammals and fish may have lost their color vision over time as it was not advantageous in the water.

Seriously?

R..

Sharks see in monochrome.

Whenever I anticipate diving in close proximity to sharks I wear as much black as possible, including suit, hood, fins, gloves, and etc. My CCR is black as are my O2 and diluent cylinders. Open circuit cylinders are either unpainted or dark grey enameled steels, and hoses are all black. Only usual exceptions to my all dark policy are the line on my spools/reels which are dirty white or yellow, and my dark orange lift bag and SMB. The whole idea is not to wear anything that could easily be perceived as a fish. (Think of the phrase “fish-belly white.”)


A common suggestion for many commercial operations is to either mandate or suggest that divers adhere to an all dark colored gear protocol. Enforcement of this policy varies according to the individual operator.
