 How did almost 90% of the snow crab population disappear? The answer is darker than you think. It's not because we've been eating too much of them. They're actually feasting on each other. But weirdly enough, the snow crab population boomed a couple years ago. So why are they going full handable lector on each other? It's because the larger crab population depletes resources in the area and warmer temperatures force them to expend more calories. You could say all that makes a crab hangry, so they have to resort to cannibalism. Experts also believe that some snow crabs are migrating out of their usual habitat for colder waters further north. Others think a disease might be causing this disappearance. Or that the warmer waters invite more predators. Regardless of what caused it, Alaska canceled the snow crab season for the first time ever. So if you actually see it on the menu, consider ordering something else to give these poor guys a break.
