Quick Quiz- everyone should learn one new thing every day

OK which is the shark responible for the most fatal attacks on humans?
a)Tiger
b)Port Jackson
c)Great White
d)Reef blacktip
e)Oceanic whitetip
f)Whale
g)blue
h)Mako
i)Pool shark
I'll try just adding this down the bottom so these are continually linked. The answer is....
e) The Oceanic Whitetip shark. (not to confused with common reef whitetip sharks which are smaller and thinner and have smaller fins)
The oceanic whitetip shark, Carcharhinus longimanus, is a large pelagic shark of tropical and warm temperate seas. It is named after its oceanic habitat (living in deep waters), and the white tips of its fins. It is a stocky shark, most notable for its long, rounded fins.

This aggressive but slow-moving fish dominates feeding frenzies, and has attacked more humans than all other shark species combined — it is a notable danger to survivors of oceanic ship wrecks and downed aircraft. Recent studies have shown that its numbers are in steep decline — its large fins are highly valued as the chief ingredient of shark-fin soup and, as with other shark species, the oceanic whitetip faces mounting pressure from fishing throughout its range (Wikipedia)
Famed oceanographic researcher Jacques Cousteau described the oceanic whitetip as "the most dangerous of all sharks". Despite the greater notoriety of the great white shark and other sharks habitually found nearer the shore, the oceanic whitetip is considered responsible for more fatal attacks on humans than all other species combined, as a result of predation on those shipwrecked or from aircraft downed in the open ocean. These incidents are not included in common shark-attack indices for the 20th and 21st centuries, but would appear to total in the thousands worldwide, with one incident alone, the torpedoing of the USS Indianapolis on July 30, 1945, giving a minimal figure of 60–80 killed by sharks. Also during World War II, the Nova Scotia, a steamship carrying approximately 1000 people near South Africa was torpedoed and sunk by a German submarine. There were only 192 survivors, and many deaths were attributed to the oceanic whitetip shark.
Even though the oceanic whitetip is highly opportunistic and aggressive; and has been known to attack humans for food, divers have swum with this shark repeatedly without being harmed (it is a popular draw for dive tourism because of its size and the perceived danger). However, divers are advised to approach the shark only with extreme caution, not spear fish near this shark and if the shark comes too close or gets too inquisitive to get out of the water as soon as possible. It is generally suggested that if a shark starts to push the diver, then to hit it on the snout, gills or eyes, but anecdotal evidence suggests that this may be less effective in deterring whitetips than with other species of sharks.
So there you go. Even a spearfishing friend was suprised by this so i hope everyone has learned something.

My guess is tiger shark.

well i'm thinking that more people would be injured by jumping from a pool edge onto a pool shark, falling off and hitting their head on the edge, or a fellow swimmer... that being said i'm going with tiger...

That's a very good point cam but not actually the type i was thinking about. I was thinking of the pool playing specimen. but did you know more people die from coconuts falling on their heads every year than from shark attacks?

well i disagree... to my knowledge there is no international coconut mortality journal... medical journals do make reference to some coconut related injuries... but not much... personally... i'd prefer to snuggle up to a coconut tree than a shark... but hey... each to their own!

http://unisci.com/stories/20022/0523024.htm is what one expert states but agreed after cafeful research I'll try annother one. You have more chance of dying in your armchair watching JAWS than actually being attacked.

"aggressive but slow-moving fish" ... c'mon Tim!! Sharks aren't fish! ;P

Damnit... my first inclination was "white tip/white point something..." but because I didn't think I'd ever heard of "Oceanic" i ditched it :P

Oh well ^_^

NEXT!!

sting rays sound pretty deadly (literally not colloquially)
