Think about the horror of shark researchers once they noticed a 15m shark-shaped blob on their underwater motion detector.
The large pink blob appeared and moved like a shark, and would have weighed an estimated 40 tons.
For a second the researchers thought they had been taking a look at a megalodon, a prehistoric shark that has been extinct for 3 million years.
However as researchers from the Atlantic Shark Institute watched in perplexment and fascination, the alarming pink blob scattered into hundreds of smaller fish.
What researchers had been taking a look at was really a crowded college of Atlantic mackerel, which simply occurred to tackle the form of a large shark.
Atlantic mackerel are inclined to huddle shut collectively as a searching method.
Slightly than individually hunt for plankton and different morsels, mackerel crowd collectively in a tightly packed phalanx.
Evading a single mackerel is tough sufficient for a plankton, however ending up a tasty snack is inevitable when you find yourself confronted by a wall of fish mouths.
Scientific proof factors to megalodon having lived between 16 million and a pair of.6 million years in the past, going extinct on the finish of the Pliocene Epoch when the world's oceans had been a lot colder than at present's.
Megalodons are finest remembered for being the antagonist within the movie The Meg, which is thought to be one among Jason Statham's most lifelike motion pictures.
