Friday Squid Blogging: Creating Batteries Out of Squid Cells

This is fascinating:

“When a squid ends up chipping what’s called its ring tooth, which is the nail underneath its tentacle, it needs to regrow that tooth very rapidly, otherwise it can’t claw its prey,” he explains.

This was intriguing news ­ and it sparked an idea in Hopkins lab where he’d been trying to figure out how to store and transmit heat.

“It diffuses in all directions. There’s no way to capture the heat and move it the way that you would electricity. It’s just not a fundamental law of physics.”

[…]

The tiny brown batteries he mentions are about the size of a chiclet, and Hopkins says it will take a decade or more to create larger batteries that could have commercial value.

Friday Squid Blogging: Another Giant Squid Captured on Video

Here’s a new video of a giant squid, filmed in the Sea of Japan.

I believe it’s injured. It’s so close to the surface, and not really moving very much.

“We didn’t see the kinds of agile movements that many fish and marine creatures normally show,” he said. “Its tentacles and fins were moving very slowly.”
