Friday Squid Blogging: Flying Squid

Who knew?

“Hulse was shooting with burst mode on his camera, so I know exactly what the interval is between the frames and I can calculate velocity of squid flying though the air,” O’Dor says. “We now think there are dozens of species that do it. Squid are used to gliding in the water, so the same physiology probably allows them to maneuver and glide in the air. When you look at some of the pictures, it seems they are more or less using their fins as wings, and they are curling their arms in [a] shape that could easily be some kind of lifting surface.”

Friday Squid Blogging: Squid Sex Organs

Riddles of squid sex:

All cephalopods are hindered by their body shape, which comprises a closed hood-type structure called a mantle, which forms most of what appear to be a cephalopod’s body and head.

The animals use this mantle to move via jet propulsion, they must ventilate it to breathe, and they must also hide their excretory and sexual organs within its structure.

That poses a challenge to male cephalopods: how do they get their sperm past this mantle, and how does the sperm stay there when water is being forcibly passed through the mantle cavity so females can move and breathe?
