Friday Squid Blogging: Squid Eyeballs

Details on how a squid’s eye corrects for underwater distortion: Spherical lenses, like the squids’, usually can’t focus the incoming light to one point as it passes through the curved surface, which causes an unclear image. The only way to correct this is by bending each ray of light differently as it falls on each location of the lens’s surface….

Details on how a squid's eye corrects for underwater distortion:

Spherical lenses, like the squids', usually can't focus the incoming light to one point as it passes through the curved surface, which causes an unclear image. The only way to correct this is by bending each ray of light differently as it falls on each location of the lens's surface. S-crystallin, the main protein in squid lenses, evolved the ability to do this by behaving as patchy colloids­ -- small molecules that have spots of molecular glue that they use to stick together in clusters.

Friday Squid Blogging: Giant Squids Have Small Brains

New research: In this study, the optic lobe of a giant squid (Architeuthis dux, male, mantle length 89 cm), which was caught by local fishermen off the northeastern coast of Taiwan, was scanned using high-resolution magnetic resonance imaging in order to examine its internal structure. It was evident that the volume ratio of the optic lobe to the eye in…

New research:

In this study, the optic lobe of a giant squid (Architeuthis dux, male, mantle length 89 cm), which was caught by local fishermen off the northeastern coast of Taiwan, was scanned using high-resolution magnetic resonance imaging in order to examine its internal structure. It was evident that the volume ratio of the optic lobe to the eye in the giant squid is much smaller than that in the oval squid (Sepioteuthis lessoniana) and the cuttlefish (Sepia pharaonis). Furthermore, the cell density in the cortex of the optic lobe is significantly higher in the giant squid than in oval squids and cuttlefish, with the relative thickness of the cortex being much larger in Architeuthis optic lobe than in cuttlefish. This indicates that the relative size of the medulla of the optic lobe in the giant squid is disproportionally smaller compared with these two cephalopod species.

From the New York Times:

A recent, lucky opportunity to study part of a giant squid brain up close in Taiwan suggests that, compared with cephalopods that live in shallow waters, giant squids have a small optic lobe relative to their eye size.

Furthermore, the region in their optic lobes that integrates visual information with motor tasks is reduced, implying that giant squids don't rely on visually guided behavior like camouflage and body patterning to communicate with one another, as other cephalopods do.

Friday Squid Blogging: Eyeball Collector Wants a Giant-Squid Eyeball

They’re rare: The one Dubielzig really wants is an eye from a giant squid, which has the biggest eye of any living animal — it’s the size of a dinner plate. "But there are no intact specimens of giant squid eyes, only rotten specimens that have been beached," he says. As usual, you can also use this squid post to…
