The sarcastic fringehead (Neoclinus blanchardi) is this week’s Fish of the Day. Enthusiasts will (or won’t) enjoy this puzzler from Mark W. Denny and Steven Gaines’s book Chance in biology: using probability to explore nature:
Suppose that a displaced sarcastic fringehead must spend approximately three hours searching for a new shelter. Lets’ also assume that each day involves four encounters with invading fringeheads…. How much time will a fringehead waste in a typical day searching for a new shelter?
(Thanks to investigator Lance Gharavi for bringing this to our attention.)
