A great white shark attack left tourists screaming in terror as the water turned blood red.
Families on board a whale-watching tour boat witnessed the predator sink its teeth into a seal neard Green's Point Lighthouse in Brunswick, Canada.
Video footage captured by captain Theophilos Tsagkaris shows the shark's fin slicing through the surface of the water as it attacks the helpless mammal.
Whale-watchers can be heard screaming as the drama unfolded just yards from the boat deck.
Tour organiser Jolly Breeze Tall Ship & Jolly Hurricane Jet Boat posted the video on their Facebook page yesterday, where it attracted over 26,000 views within hours.
Marjorie Sorour commented that it was the third time they had witnessed a seal attack in the last six weeks and it always happened at the same spot.
"It's fair to say its their new preferred feeding ground for seals," she said.
Senior marine biologist Nicole Leavitt-Kennedy said six main species of sharks reside in the Bay of Fundy and similar sightings are not a total rarity.
She told CTV News in an interview last month: "We have white sharks, basking sharks, blue sharks, porbeagles, threshers and makos.
"I'm not going to say they're as common as you would see them every time you go out on the ocean - but they are there."
