Among the many arthropods we willingly share our home with are the so-called silverfish of the order Thysanura. We leave them alone and in return, they provide me with occasional opportunities to photograph them.
This individual was about 10 mm long.
"They are odorless and harmless, and serve to remind us of how ephemeral we are-and how ephemeral our books and records are, for silverfish live on the sizing of paper and the bindings of books. I keep my American Scientist in the attic for the silverfish to eat, although I have heard that they do equally well on Playboy or The Watchtower."
