  • "The adult crabs, like many other species, live in groups divided by sex when they are not molting or mating. The males can migrate up to 100 miles in a year, moving at times as fast as a mile per day in massed male-only configurations, like rolling balls on the sea floor. They eat worms, clams, mussels, snails, brittle stars, sea stars, sea urchins, sand dollars, barnacles, other crustaceans, fish parts, humans if they can find one, sponges, algae—and other king crabs. And they are eaten by cod, halibut, octopuses, sea otters, nemertean worms—and other king crabs."

  • Yeah, you call that catching a crab. It doesn't always throw you out of the boat (a bad one at high speed will) but it's kind of painful and not exactly great for race momentum.

  • An older grouchy word is crab, which comes not from the crustacean but the sour crab apple, which in turn may come from Swedish dialect word skrabba, “fruit of the wild apple-tree,” according to the Oxford English Dictionary (OED). Crab came to refer to a sour person in the 1570s.--- Wordie: Errata 29 Jan 2013
