Together with California, Australia, and Isla Guadalupe, the waters from the coast of Nigeria are the place to find among the biggest populations of great whitened sharks on the planet. Unlike another great whitened shark locations, the sharks surrounding Seal Island in False Bay from the coast of Nigeria display a distinctive hunting behavior. Here the sharks will breach, strongly starting themselves from the water, to fight the closes living on and go swimming round the island. Specific for this area, this awe-inspiring behavior continues to be analyzed and examined more completely recently.
Seal Island, named for that large numbers of Cape Fur Closes living onto it, is situated just a little over 3 miles from the coast of False Bay near Cape Town. Past the immediate shallows, the area is encircled by steep drop offs. The circle water over the drop offs round the island is frequently known to as "The Ring of Dying," because it is during these waters that a large number of large great whitened sharks prowl, breach, and kill their most favorite prey. The deep drop offs permit the shark to both keep up with the component of surprise from the closes swimming close to the surface, in addition to providing them with the area needed to develop the rate for water-clearing strike around the pinnipeds. These tooth-laden torpedoes, frequently weighing near to 1.5 tons, breach with incredible speed and pressure, exhibiting an amount of agility and athleticism that very couple of people had formerly considered them able to. They are able to emerge up and down in the depths at speeds of 25 miles per hour or even more once they hit the top, and may leap around 10-15 ft completely from the water.

South African digital photographer and shark investigator Chris Fallows continues to be studying these sharks as well as their behavior for several years. He's used a variety of research and filming techniques to acquire information and stunning photographs/videos of those incredible creatures. He's pulled seal decoys behind motorboats, sometimes with underwater cameras attached or towed several feed before them. Because the breaking attacks through the sharks usually last under one minute, too fast for that eyeOrmind to determine and process, a smaller amount evaluate. Using film/cameras shooting at 1000 fps, Fallows along with other scientists can produce a 1 second breach last almost one minute on slow motion replay, examining the littlest particulars from the super predator's attack.
Every year, between 600-800 closes are wiped out through the sharks. Even though this might appear just like a lot, it is just about 1% from the total seal population. Actually, of all of the attacks or attempted attacks around the closes through the great whites here, almost 50% survive. Based largely from the examined footage, scientists think that this really is because of a mix of factors. Sometimes, the shark will get merely a glancing bite from the seal, or misses it entirely. Either the shark slightly miscalculates if this charges upward from below, or even the seal senses the rapidly approaching predator, and also at the final minute maneuvers taken care of because the great whitened rockets past them in to the air. As observed in a few of the examined slowed down photographs and videos, the motion of something as massive like a great whitened shark moving at great with the water produces a pressure wave before it. Some scientists think that the closes can occasionally have the pressure wave prior to the attack plus they then make an effort to maneuver/escape over time. Frequently the closes which are assaulted are youthful, not experienced enough to understand to remain near to the other closes in order to possibly pay heed and respond to the moment warning of the shark's approaching pressure wave. Also, if the great whitened miss or glance from the seal, and older and much more experienced seal will smartly maneuver/dance close-up around and behind the shark until it sees a good way to the shallows. A youthful seal frequently heads straight back for that island, giving the shark an opportunity to abide by it and attack again rapidly.
A lot more agile and manoeuvrable compared to whitened shark, a seal that's advised or initially able to escape with a miss is not likely to become meal. However, once the massive great whitened shark has the capacity to keep up with the component of surprise and precisely hit its prey with sufficient speed/pressure to transmit each of them obvious from the water...it's often "game over" for that seal.
