Squid Drawn from 150 million-year-old Ink

Posted by Miss Cellania in Animal, Science & Tech on August 23, 2009 at 7:04 am

Scientists found the fossil of an ancient squid of the species Belemnotheutis antiquus at a dig near Trowbridge, England, when they reopened an archaeological site that had been abandoned for 170 years. Inside there was a one-inch black ink sac that still contained ink granules. As an experiment, researchers ground up a small portion of the ink and dissolved it in an ammonia solution. Then they used the sample to draw a picture of what the squid may have once looked like! Excavation leader Dr. Phil Wilby said,

“It is difficult to imagine how you can have something as soft and sloppy as an ink sac fossilised in three dimension, still black, and inside a rock that is 150 million years old.

“The structure is similar to ink from a modern squid so we can write with it. I suppose we could theoretically use it for food colouring, too, but I don’t think I will try tasting it.”

A sample of the ink has been sent to Yale University for further analysis. Link -via the Presurfer

Squids Can See Without Eyes

Posted by Alex in Animal, Science & Tech on July 11, 2009 at 11:00 am

The evolution of the eye is fascinating stuff (in a nutshell, the eye is so complex that Creationists claim that it couldn't possibly have evolved ... and scientists countered that not only did the eye evolved into being, it is so useful that it did so more than one time)

Well, add this to the mix: Margaret McFall-Ngai and colleagues at the University of Wisconsin-Madison have discovered that squids can detect light through an organ other than their eyes (and if that's not cool enough, it's done through a symbiosis with luminous bacteria!):

"Until now, scientists thought that illuminating tissues in the light organ functioned exclusively for the control of the intensity and direction of light output from the organ, with no role in light perception," says McFall-Ngai. "Now we show that the E. scolopes squid has additional light-detecting tissue that is an integral component of the light organ."

The researchers demonstrated that the squid light organ has the molecular machinery to respond to light cues. Molecular analysis showed that genes that produce key visual proteins are expressed in light-organ tissues, including genes similar to those that occur in the retina. They also showed that, as in the retina, these visual proteins respond to light, producing a physiological response.

"We found that the light organ in the squid is capable of sensing light as well as emitting and controlling the intensity of luminescence," says co-author Nansi Jo Colley, SMPH professor of ophthalmology and visual sciences and of genetics.

Skot Olsen's Cephalopod Artwork

Posted by Alex in Arts & Crafts on January 3, 2009 at 2:19 pm

"Neatorama isn’t a cephalopod blog," but here’s a marvelous art of squid art by Skot Olsen, titled "Blessed Saint Architeuthis" (2008). Skot loves the sea but was stung by a jellyfish at a tender young age, which explains a lot about his artwork: Link – via Ectoplasmosis

Candice Tripp's Artworks

It’s hard to describe Candice Tripp’s art – it’s a little dark and macabre but with a touch of gentle humor. This one is titled "The Escape" – and yes, that’s a splotch of ink on the girl’s head: Link – via Misadventures in Crazytown
