The beast looked like Cthulhu, but no. Sadly. The real creature behind Monday’s challenge was this leggy monster:

Scutigera coleoptrata - the house centipede

Ten points to Tom Schmeelk for a quick and correct answer. And, two bonus points to ihatephids for pointing out the resemblance to our watery master.

Also, two more points to Andrea Walker, a new grad student here at UI, for kindly catching the centipede for us.
