Dr. Kenneth Catania from Vanderbilt University presented his work with star-nosed moles at the Experimental Biology meeting last month in Chicago. These animals are really cool. Here are some facts from Dr. Catania about these crazy-looking creatures you may not know:

  1. If participating in a bug-eating contest, they would win hands down every time because they are the fastest-eating mammal known. In fact, they can identify and consume a bug in a record less than two tenths of a millisecond. This is possible thanks to neurons that communicate information from the environment to their brain at speeds that are near physiological limits. I couldn’t even choose between coffee or tea in that amount of time.
  2. With over 100,000 nerve fibers, their star-nose touch organ is the most sensitive to touch among mammals. Compared to our fingers, their nose has 5 times as many nerves. Could you imagine 5 times more sensitivity in your hands?
  3. Their star-shaped organ is kind of like our eyes as the center of the organ is what they use to explore the environment more closely. They are known to explore areas of interest in the environment with the center of the organ just like humans would shift their gaze to focus on objects.
  4. It is possible to actually see which areas of their brain map to specific body parts just by using special dyes. For humans, the process of mapping what areas of the brain control which body parts requires a lot of trial and error.
  5. Perhaps my favorite characteristics: They can smell while underwater and their front legs work like shovels to make tunnels through marshy areas where they hunt for food.

    Speaking of moles, I keep telling the Amiga Mole about this ScienceBlogs website, because a long time ago in a galaxy far, far way, he used to write articles for me in the Revista Amigable Commodore Amiga newsletter of which I was the usurpative editor, having wrested control away from the Lakeside School Latin teacher (ret.) who had a Ph.D. in maybe astronomy from Columbia University, and who was instrumental in the arise of Microsoft because said Latin teacher had the Mothers’ Club donate $1,000 to computer time-share for the likes of Gates and Allen who used it up in a matter of months. On the Amiga, the retired Lakeside teacher coded astronomy programs like “photon walk”, and I created animations like you see at http://mindsz.com/ideasz/ai-mind and at http://ai.neocities.org/maintainer.html for future jobs. The Amiga Mole last week jumped to the conclusion that http://scienceblogs.com must be an aggregator, but I said, no, it was a place where eminent scientists post their original write-ups. Now this eminent post upthread from here looks like maybe it is indeed an aggregated item, and only “posted”, not artificed, by Dr. Doolittle. Still it’s a nice piece, but before I got so carried away, I just wanted to mention that the item leaves out the Latin name of the said mole, “Condylura cristata”, as per my http://en.wikipedia.org/wiki/Star-nosed_mole source.
