A spider crab molts

The scale is deceptive. This is not the ordinary crab we’re used to, but a giant Japanese spider crab (Macrocheira kaempferi), whose leg span (3.8 meters or 12.5 feet) and weight (up to 19 kg. or 41 lb.) make it the largest arthropod in the world. This time-lapse video was shot over a 6-hour period.
