Giant Squid Hunt For Prey

First-of-Its-Kind Video Shows How Giant Squid Hunt Their Prey Deep in The Ocean...

In the permanent twilight of the mesopelagic, a silent predator hunts.

The enigmatic giant squid is rarely observed in its natural habitat. In the first videos of their kind, unveiled in 2021, marine scientists caught its hunting behavior in the wild – revealing for the first time how these monsters of the deep stalk and attack their prey.

Although the crushing pressures and darkness of the oceanic depths are hostile to us air-breathing humans, we've slowly but surely been learning more about them, thanks to the wonders of robotic technology. Most of our underwater vehicles, however, are best suited to studying slow or immobile organisms.

For giant squid, the bright lights mounted on underwater vehicles can be uncomfortable for their sensitive, low-light eyes, which can grow to the size of dinner plates; the sound and vibration can also scare off more mobile animals. And, of course, bringing giant squid to the surface won't record their behavior in their natural environment.

That's why a team of researchers led by Nathan Robinson of the Oceanographic Foundation in Spain devised a different solution: a passive deep-sea platform, equipped with a camera. Because giant squid eyes are optimized to see shorter-wavelength blue light, they used longer-wavelength red lighting that won't annoy them, in order to see the animals on video.  READ MORE...
