Friday Squid Blogging: Humboldt Squid Can Dive to 1.5 km

Yet another impressive Humboldt squid feat:

“We’ve seen them make really impressive dives up to a kilometre and a half deep, swimming straight through a zone where there’s really low oxygen,” the Hopkins Marine Station researcher said.

“They’re able to spend several hours at this kilometre-and-a-half-deep, and then they go back up and continue their normal daily swimming behaviour. It’s just a really impressive, really fast, deep dive through what is quite a harsh environment.”

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Friday Squid Blogging: Squid Can Fly to Save Energy

There’s a new study that shows that squid are faster in the air than in the water.

Squid of many species have been seen to ‘fly’ using the same jet-propulsion mechanisms that they use to swim: squirting water out of their mantles so that they rocket out of the sea and glide through the air. Until now, most researchers have thought that such flight was a way to avoid predators, but Ronald O’Dor, a marine biologist at Dalhousie University in Halifax, Canada, has calculated that propelling themselves through the air may actually be an efficient way for squid to travel long distances.
