Larger crabs or crabs with less suitable shells will often forcibly remove other crabs with more desirable shells by clasping the chelae, or legs, of the occupant with its pincers, which allows them to takeover the desired shell. [4] [12] Along with predation, shell availability is a major factor in determining P. longicarpus population size. [7]
Mictyris longicarpus, the light-blue soldier crab, is a species of crab that lives on sandy beaches from the Bay of Bengal to Australia; with other members of the genus Mictyris, it is "one of the most loved crabs in Australia". [2] Adults are 25 mm (1 in) across, white, with blue on their backs, and hold their claws vertically.
Mictyris is a genus of brightly coloured crabs, placed in its own taxonomical family, the Mictyridae. [1] It inhabits the central Indo-West Pacific region. These crabs congregate on mud flats or beaches in groups of a few thousand, and filter sand or mud for microscopic organisms.
Pagurus is a genus of hermit crabs in the family Paguridae.Like other hermit crabs, their abdomen is not calcified and they use snail shells as protection. These marine decapod crustaceans are omnivorous, but mostly prey on small animals and scavenge carrion.
A hermit crab emerges from its shell, Coenobita perlatus Outside its shell, the soft, curved abdomen of hermit crabs, such as Pagurus bernhardus, is vulnerable. Hermit crab species range in size and shape, from species only a few millimeters long to Coenobita brevimanus (Indos Crab), which can approach the size of a coconut and live 12–70 years.
