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