Both photos of these hermit crabs were taken at night. This crab can reach up to 15 cm and as such is one of the largest hermit crabs on the world. It likes to eat jellyfish and cephalopods. As shown below this crab likes to grab the shells of different sea slugs to hide inside (first photo probably Melo sp., second photo probably Pleuropoca sp.).
