Like most animals, the King Crab grows larger as it ages. However, its carapace does not grow with it. As they age, the crabs must molt and grow new shells (which are made primarily of calcium). This molting process happens much more often when they are juveniles, and less when they are adults and have more or less plateau'd in size. King Crabs can live 25-30 years, and crabs that make it to those ages can be as many as five feet in leg span. King Crabs feed on all sorts of small marine life, including each other. They are preyed upon by fish, octopuses, and otters.
