The Economist daily briefing highlighted the work of Dr Edith Widder, who has been recording giant squid.
Her lab’s paper gives the context:
The legend of the “kraken” has captivated humans for millennia, yet our knowledge of the large deep-sea cephalopods that inspired this myth remains limited.
They have some great hardware to figure out what’s going on. The remote camera system can extend 2 km down into the ocean, and record video for 48 hours. The figures in the paper are wonderful at explaining the setup:
Of course, it’s the stills of the squid that caught my eye. Figure 5, for example, estimates the arm of one squid to be 1.68 m long:
Before this, I wasn’t even sure if these animals were real or just exaggerations from sailors tales! I recommend watching the 5 minutes of video that is “Supplementary Materials 6”. It’s slightly spooky, a little tense, but more in a James Cameron style then Ridley Scott.
