Shark Week 2013: 'Megalodon: The Monster That Lives' 'Fake Documentary' Angers Viewers; Discovery Channel Defends Program (WATCH)

Shark Week fans were confused and angered Sunday night when the Discovery Channel aired, "Megalodon: The Monster That Lives" an investigation over of an enormous shark that possibly swims in seawaters today.

Why were fans angered? Megalodon no longer exists and the Discovery Channel special did not make that clear until the end. The reason why people tune into Shark Week is for the scientifically proven documentaries, not potentially fictitious accounts.

The message read:

"Though certain events and characters in this film have been dramatized, sightings of [the giant creature] continue to this day. Megalodon was a real shark. Legends of giant sharks persist all over the world. There is still debate about what they might be."

It wasn't soon before long until viewers took to social media to express their outrage.

"Why does the description on [the Discovery Channel Facebook page] say you are dedicated to producing high quality NON-FICTION shows when you kicked off Shark Week with a 100% fictional story???? Please explain. Shark Week just died a little for me," one user wrote network's Facebook page, according to Fox News.

"I hope you Discovery Channel producers are taking the hint... you have FAILED your, clearly, dedicated Shark Week fans. Bring back Mike Rowe and REAL documentaries. This episode was a MEGA-failure," another Facebook user commented on the Shark Week page.

However, Michael Sorensen, the executive producer of Shark Week, defended the decision to include the film in this year's programming.

"With a whole week of Shark Week programming ahead of us, we wanted to explore the possibilities of Megalodon," Sorensen told FOX411 in a statement. "It's one of the most debated shark discussions of all time, can Megalodon exist today? It's Ultimate Shark Week fantasy. The stories have been out there for years and with 95% of the ocean unexplored, who really knows?"

"Megalodon: The Monster That Lives" will re-air on Aug. 11 at 10 a.m. ET. on the Discovery Channel.
