You'd never guess what this is

"Sperm tails tangled up in a seminiferous tubule"

Credit Clifford Barnes, posted in the Flickr photostream of the FEI Company (which, BTW, has lots of neat SEM images), via Dr. Sci-Phy.


  1. it's a piece of rat testes tissue which had been fixed in formalin before post fixation in osmium tetroxide.

  2. "...tails tangled up" got me thinking of this: http://en.wikipedia.org/wiki/Rat_king_%28folklore%29

    And from there the mental picture just descended further and further down the hole of bizarre sexual imagery
