What species of shark are dangerous to scuba dive with?

Any shark that is deemed a 'maneater'. These may include Bull Sharks, Tiger Sharks, Mako sharks, Hammerheads and of course Great White Sharks. It is also dangerous to scuba dive with Blue Sharks, Oceanic White Tips, Thresher Sharks, and any other sharks known to be territorial and agressive. Most Thresher Sharks are found in the open ocean, as well as Oceanic White Tips(hence the name). Blue Sharks tend to be all over. Bull sharks usually frequent sand bars and murky waters. Tigers, Mako, Hammerheads and Great Whites are widespread and can be anywhere from the open ocean to within 200 feet of coastline.

ANY shark, in theory, is dangerous to scuba dive with. Although many predatory sharks are not man eaters, that does not mean they won't come up and take a curious bite. Once the blood is drawn, that one bite may lead to another, and so on. If you ever plan to go scuba diving in a shark-infested area, be sure to do so with a group of at least 4 other people, as well as experienced, professional divers who can help you if you get into a dangerous situation. Always respect that you are in their environment, and that by invading their territory you are inviting a potential attack. If there are sightings of Great Whites, Makos, Bull or Tigers in the area, do not dive in that vicinity. Although Bull Sharks may not attack on sight, they ARE predatory and within the past few years have been responsible for more shark attacks than any other shark. Be careful.

Sharks in general are not dangerous to humans. Only a few species have "man-eater" status and that comes from years of mis-understanding of these creatures. For example Gorillas were once thought to be man killers. Today we know more about them and they are not considered dangerous.

The bad boy shark list for scuba divers runs from Bull Sharks to Tigers. Although more people get nipped by sharks just swimming than on scuba. In fact you're much less likely to be attacked by a shark while on scuba.

The best bet, when in doubt, do not dive and never dive with feeding sharks.

It depends where you want to dive. Most sharks are not dangerous; and they are more scared of us then we are of them. Find out what sharks live in the area before you scuba dive. Besides, Great Whites and Tiger Shark are actually rare.

Sharks can be dangerous, yes, but only five are truly dangerous to man. The Blue Shark, The Bull Shark, The Tiger Shark, The Great White Shark, and...um, I'm missing one. What is it? Oh yeah, the Hammerhead Shark. Anyway, these are easy to spot. If you see a sly blue shark (Blue Shark), a large grey shark in fresh water (Bull Shark), a grey and black striped shark (Tiger Shark), a huge blue shark (Great White), or a weird looking headed one (Hammerhead Shark), then get out of the water. Sharks aren't really dangerous, though. Love them, and avoid the dangerous ones. That's all you need to know.
