In mid-2017, four giant white sharks were found in such a strange state of tragedy: just being lured, hooked. The mystery so far has not been satisfactory, although the "suspect" has been determined.
The world has turned into 2018, but there are still unexplained mysteries that have originated in 2017. And one of them is the fact that giant white sharks float on the coast of South Africa, in condition of losing the liver.
More specifically, in mid-2017, South African oceanographers had to witness a very strange phenomenon. They have found four times the giant white shark that washed ashore Franskraal with a loss of liver, including two cases of losing the heart.
Speaking of which, everyone understood that they were the gods of the ocean. The largest in the shark family, the great jaw and sharp teeth, the white shark is one of the creatures that stands at the top of the food chain, and almost only the enemy is human.
The bad sharks found are also not small. The nearest child found at the end of June 2017 is a male 4.1m long (the largest individual ever washed ashore is only 4.9m long). This is also the most tragic case, when losing both liver, stomach, testes - and signs that it has lost a lot of blood before leaving.
But what is capable of creating such a great tragedy? All doubts are pouring into assassin whales (orca) that have wandered in the Frankraal Sea area - where the corpses of the above-mentioned sharks have been found.
In addition to humans, are creatures that qualify to handle a white shark neatly.
First, in terms of size, killer whales are better than white sharks in both weight and body length. They also possess extremely powerful jaws and more than 50 sharp teeth, which are extremely smart. And most importantly, they often hunt in the herd of 3-5 animals. All have turned killer whales into natural enemies of white sharks.
"The killer whales have been wandering in the area where the" murder "occurred" - some reports said. "The tracking ships suddenly found no signs of white sharks. They are likely to flee because of the pursuit of killer whales."
The act of hunting only parts of killer whales is not too rare. Science once recorded some cases of this animal when hunting whales, they only eat tongue, because it is the one that provides the most energy.
But why killer whales targeting white sharks are what scientists are feeling headaches. The truth is that even if it is an enemy, the killer whale's choice of shark hunting is relatively reckless. Anyway, these are opponents that are not easy to handle, so they usually target only whales, sea lions and seals.
Moreover, organs of white sharks - especially liver - are not enough to compensate for the losses caused by the attack. To win a white shark, killer whales will have to invest a lot of energy, and the results seem unworthy.
Besides, some animals such as sea lions have also appeared to attack offal hunting sharks. But it was just a small shark, not as big as the bad fish mentioned above.
And finally, the attack on the shark was judged to be very accurate, as if the enemy had a clear grasp of the shark's visceral position.
So, the case is still in mystery. The biggest suspect is still some killer whales, but things will only be officially concluded when there are more facts, such as videos or images, for example.
