Friday Squid Blogging: The Evolution of Squid Eyes

New research:

The researchers from the FAS Center for Systems Biology discovered a network of genes important in squid eye development that are known to also play a crucial role in limb development across animals, including vertebrates and insects. The scientists say these genes have been repurposed in squid to make camera-lens-type eyes.

Friday Squid Blogging: Deep-Dwelling Squid

We have discovered a squid — (Oegopsida, Magnapinnidae, Magnapinna sp.) — that lives at 6,000 meters deep.

:They’re really weird,” says Vecchione. “They drift along with their arms spread out and these really long, skinny, spaghetti-like extensions dangling down underneath them.” Microscopic suckers on those filaments enable the squid to capture their prey.

But the squid that Jamieson and Vecchione saw in the footage captured 6,212 meters below the ocean’s surface is a small one. They estimate that its mantle measured 10 centimeters long — ­about a third the size of the largest-known magnapinnid. And the characteristically long extensions observed on other magnapinnids were nowhere to be seen in the video. That could mean, says Vecchione, that this bigfin squid was a juvenile.

Friday Squid Blogging: UK Recognizes Squid as Sentient Beings

This seems big:

The UK government has officially included decapod crustaceans–including crabs, lobsters, and crayfish–and cephalopod mollusks–including octopuses, squid, and cuttlefish–in its Animal Welfare (Sentience) Bill. This means they are now recognized as “sentient beings” in the UK.
