Once in a while, the keen eye of a citizen scientist observes something quite remarkable—like a mass migration involving thousands of tanner crabs.
“Why are these crabs massing at Barkley Canyon?” asked a postal worker from Minnesota. ONC staff scientist Fabio De Leo weighs in on this rarely viewed event.
