The mystery of the 40-ton shape that appeared on the scanner of the Atlantic Shark Institute has been solved.

The question on everyone's mind when the shark scanners detected a 50-foot-long mass in the depths of the ocean was: "Does the Meg exist?"

The Megalodon, or simply "Meg," was a giant shark that roamed the oceans some 20 million years ago and is known to be the largest shark species to ever exist. For those who are unfamiliar with this creature.

The Meg, a giant-toothed mackerel shark, gained widespread recognition in 2018 as the subject of a hilarious shark movie.

As stated by the Natural History Museum: "O. megalodon was not only the biggest shark in the world but one of the largest fish ever to exist. Estimates suggest it grew to between 15 and 18 metres in length, three times longer than the largest recorded great white shark."

Upon seeing the massive shape on their shark scanner, researchers were excited about the potential discovery and took to Instagram to share their findings with others.

"On a recent shark research trip we were all amused to see this shape appear on our fish finder for several minutes. Based on the length of the image we estimated the 'Meg' to be about 50 feet long, weighing in at 40 tons!" the institute said.

However, the team's investigation led to the solution to the brief mystery surrounding the unusual shape on their scanner. To the disappointment of many, it was not the Meg.

"We waited for one of the rods to go off however, much to our disappointment, the shape started to transition into a large school of Atlantic mackerel that hung around the boat for about 15 minutes."

The researchers were disappointed, expressing: "So close, but so far! The Megalodon (Otodus megalodon), disappeared more than 3 million years ago and will likely stay that way, but, for a few minutes, we thought he had returned!"

One individual on Instagram quickly expressed their disappointment, writing: "I got excited for 10 seconds," while another added "Aww dang no hot girl Meg! Hehe."

A third wrote: "Haha - that would've got my heart racing" so it seems that everyone wants to find the Meg, except us, who will comfortably swim in peace knowing there's no ginormous shark in the water.
