Are they tasty?
Found this amateur video[1] on YouTube which documents hunting, preparation, and the final dish by Chamorros from Guam. In contrast to typical crabs, the abuni (pronounced ah-boo-nee; rear end of crab body) is arguably the most desirable and flavorful part. This video[2] demonstrates simple preparation by a Japanese cook; I've highlighted the abuni part, which tastes absolutely amazing despite appearances.
