The terrifying moment a huge 15ft great white shark sent divers flying about a steel cage as it thrashed about stuck in the bars has been caught in shocking headcam footage.
Divers were left gripping on for their lives as the "Big Mamma" suffered huge cuts down her side as she desperately tried to free herself.
The terrified divers swam for safety - but found it difficult to see as she had bled so heavily the water was swamped with her blood.
The toothy predator began circling a team of divers after they had descended 35ft into the ocean just off the Mexican island of Guadalupe.
As she got too close to the cage one diver desperately tried to shove her away but she turned back and suddenly crunched through the team's air supply.
As it exploded into air bubbles they lost half their oxygen supply in seconds.
