People don't realize how many sharks live in the North Atlantic, in fact waters between the Gulf of St. Lawrence and the mouth of Chesapeake (an area that includes Cape Cod obviously) have one of the densest shark population in the world in summertime. Fortunately for swimmers most temperate/cold water sharks, which tend to be very large in size, usually avoid shallow waters. It wouldn't be a good idea to fall overboard though. Fishermen often report large sharks trailing their boats. The huge mako in the picture was hooked off Cape Breton and won its captors a first prize in a shark fishing contest held in Nova Scotia. It is truly exceptionally large, must have been quite a challenge to reel in. I would have kept my hands way back from its mouth.
I did not but it doesn't surprise me, makos hang around the same waters as swordfish do, on the Grand Banks of Newfoundland and vicinity. Swordfish fishermen must catch a lot of makos and well, why not make a living off those as well if they taste ok?
In the movie
The Perfect Storm which takes place on the Grand Banks there is a rather ridiculous scene where a hooked small mako (according to the script) attacks the crew. However the shark used in the movie looks like a generic shark made of rubber. Even small makos have very long teeth, not small triangular ones like in the movie.
Not many people swim with them
Seriously, mako sharks were not considered dangerous until the 1950's when attacks originally attributed to other species (great white) were found to have been perpetrated by large makos, which are opportunistic eaters even though not suicidal ones like great whites.
The level of dangerousness posed by any particular cold water shark species is difficult to assess and this was even more so before the advent of scuba diving and the wetsuit. Makos dwelling in the Pacific are somewhat sluggish, smaller and usually harmless unless provoked (they will defend themselves with deadly force if they feel threatened but not attack at random) and thus it was assumed that all makos were relatively safe. But Atlantic makos, which are larger and not sluggish at all have been reclassified as man-eaters after a series of fatal and near-fatal encounters in the St. Lawrence river and off the coast of New England half a century ago, and it was theorized that other attacks hitherto attributed to great whites mainly due to the reported size of the attacker had in fact been committed by large makos. In the photo above it's pretty obvious that anyone seeing a shark of that size in the water could assume it's a great white based on bulk alone. There are more like it out there.
The victims of the mako attacks were fishermen and a shipwreck diver who was attacked while exploring the wreck of the
Empress of Ireland at the bottom of the St. Lawrence river. Being a diver myself a few years ago I applied for a permit to survey the Empress with a friend and that's when I learned about this (we were denied the permit and didn't complain much lol). Good thing is makos are not coast-hugging sharks so encounters are rare but let's just say they are better left alone. Many experts believe that after the great white the Atlantic mako is probably the most aggressive shark species towards humans.
You're making me hungry now, I love seafood
