Fishing is one of the most enjoyable pastimes there is in nature.

Being able to sail out on the water, grab a fishing pole and some bait, and see the beautiful sights is something many like to do. However, worrying about becoming someone’s lunch is probably the last thing on your mind.

For this lone fisherman in the video captured below, he had one crazy experience with a shark. CNN reported a fisherman who was out with a group of friends one day on a boat.

And he decided to go out on his kayak alone. 

Watch this Shark Flip Over This Kayaker!

While he was out on the kayak, he started to fish. We see him struggling with something that was caught on his hook. It was a large grouper that took the bait and set out to catch him. As he pulled it out of the water, a giant bull shark came by and ate it! 

To make matters worse, not only did the bull shark eat the grouper, but we see the man’s kayak start to rock severely.  At first, he thinks he can hold on, but we quickly see him fall off. First, he attempts to get on the back of the kayak; however, he quickly remembers there is a bull shark in that water that just stole his fish.

Giant grouper

Giant groupers can measure 8.2 feet long. These massive fish can weigh over 300 pounds.


The man quickly swims back to his friend’s boat, and they help him back on. We would assume that he would probably not want to get back in because of the shark. But, a short while later, we see him returning to the same kayak, ready to face this bull shark again.

Grouper (Epinephelinae) Facts

Groupers are fish with stout bodies and huge mouths that let them suck in their prey at a distance and gulp it down whole.


Groupers of the family Serranidae can be found in habitats residing in locations such as Africa, Central America, North America, and South America, to list a few. 

Unlike other fish with very similar sizes and lifespans, the grouper has a lot of variation. Groupers can be anywhere from 10 inches all the way to eight feet long! Groupers can also weigh anywhere from 5-800 pounds.  

Their lifespan can also be anywhere from 11-100 years long. So, as you can see, there is a tremendous difference in size (length and pounds) and in the span of their lifetime. 

Groupers are hunted by various animals, such as sharks, barracudas, and even larger grouper of their own species. Humans also are known to hunt groupers, such as in the video we saw posted below. 

As carnivores, groupers prey on sea turtles, small sharks, crustaceans, octopuses, other fish, and zooplankton for food. 

Is it Normal for Sharks to Behave This Way?

For perspective, this Great White is following behind a tandem kayak. Look how big it is in comparison!


Yes, it is completely normal for sharks, especially the “Big Three” – great white, tiger, and bull shark, which is the party in question in this video. While these types of attacks are rare, they do happen. Out of a documented 6,522 attacks since 1779, only 59 of those have been on kayakers. Bull sharks are known for their aggressive behavior and while a kayak might not attract them, the activity the kayaker is participating in is a huge attraction.

The majority of shark attacks are a case of mistaken identity and a person sitting in a vessel like a kayak doesn’t appear to be a food source. In many attacks, there was a food source nearby, as illustrated in this video, whether it be a person fishing from their kayaks or animals in the water, like seals. Recreational kayakers are less likely to encounter a shark than someone fishing.
