In a breakthrough for marine science, researchers have recorded the largest predation event ever observed. Captured off Norway’s coast, this monumental feeding frenzy saw around 2.5 million Atlantic cod devouring more than 10 million capelin within a matter of hours.
According to Oceanographic, this rare predation was documented by a team of Norwegian and MIT scientists, who used advanced underwater acoustic technology, specifically the Ocean Acoustic Waveguide Remote Sensing (OAWRS) system.
“This is happening over a monstrous scale,” explained MIT ocean engineer Nicholas Makris. By sending sound waves that reflect off fish, the team created a real-time map of the interaction, allowing them to identify individual species.

EU tax-to-GDP ratios revealed: Where citizens pay up to 45.6% Makris noted, “Cod have large swim bladders that have a low resonance, like a Big Ben bell, whereas capelin have tiny swim bladders that resonate like the highest notes on a piano.”
Atlantic cod feasting on capelin is a natural phenomenon The event itself was dramatic but likely a regular occurrence in marine ecosystems, although it has never before been captured on such a large scale. Capelin, which usually gather in vast shoals during February to spawn, attract Atlantic cod, their primary predator.
While this event involved just 0.2 per cent of the capelin population, scientists warn that declining fish populations, especially in species like Atlantic salmon, may not recover from such events in the future if climate change persists.
The threat to the ecosystem Makris remarked, “When a population is on the verge of collapse, you will have that one last shoal. And when that last big, dense group is gone, there’s a collapse.”
This research is a reminder of the risks facing the world’s oceans, where over 97 per cent of migrating fish species, including economically valuable species, are at risk of extinction.
As climate change continues to push species out of traditional habitats, understanding these predator-prey relationships could be crucial to conserving vulnerable fish populations along Norway’s coast and beyond.
Haha! I’m laughing at the thought that that fat slob actually has a wife.
It took me a second to find it, but this is what I was thinking.
They are so educated that they know everything.

The Far Side. The best!

Their cod is an awesome cod, it swims from Norway above, marked safe by the Federal gov, their cod is an awesome cod!
It’s an absolute requirement for any scientific paper to have “Climate Change” somewhere in the article in order to be published.
My husband likes to tell the story of the times that he and his father were laughing over the ‘Far Side’ in the paper, and his mother came in and always said, ‘I don’t get it’...
Sounds like the Harris campaign going after donors .
He learned the instrument in *school*.
Parliamentary, my dear Watson.
Never mind climate change, Chinese fleets will overfish many places.
I tried playing Sea Bass... it was hard just learning the scales.
You can Tuna Bass pretty easily as it has only four strings.

I bow to you,sir.

Raise you hands up high!
I just wonder if they all wear capes.
