The drone footage was captured in South Africa. It shows a nearly 4-metre long white shark, named Helen, attacking and killing a whale that is over 10 metres long. Information released alongside the video shows that the humpback whale was in poor condition and most likely something was wrong with it.
Marine biologist Ryan Johnson, who recorded the entire incident, said that the entire situation lasted about 50 minutes before Helen killed the whale. He added that the shark attack was carried out extremely methodically, with the predator focusing on strategically important points.
First, the shark attacked an extremely vulnerable spot on the tail, where it severed the whale’s artery, and then began dragging the profusely bleeding humpback whale underwater, where it eventually drowned it. According to Johnson, it is no coincidence that the shark attacked with great skill in exactly this way and in key locations.
“We’re talking about one of the biggest predators on the planet attacking and killing a representative of one of the biggest species that exists. It’s just fascinating that we live on a planet that can still surprise us with something so unusual,” – said Johnson
This method of killing whales has never before been observed in white sharks, which know full well that such an attack exposes them to a tail slap that, in the case of an adult humpback, could prove fatal.
This is another situation where ocean researchers have been able to record unusual and previously unknown behaviour of sea creatures, thanks to the use of drones. Not only do these small devices make it possible to record video footage of great quality, but they also allow us to accompany and observe many animals that are unaware of their presence or do not treat them as a threat and behave completely naturally.
The great white shark responsible for the attack is a female named Helen, well known to researchers, who was tagged with a special transmitter several years ago and has since become the most popular shark in the scientific world and among internet users.
