	It came from the sea: ’Monster’ crabs evolve a bug’s nose
		The robber crab, Birgus latro, is the world’s largest land-dwelling arthropod, with a weight reaching 4 kg and a length of more than half a meter.
		Robber crabs are perhaps most famous for their ability to climb tall palm trees in search of coconuts, which they later are able to crack open with their massive claws.
		A question not previously addressed is how the robber crabs have adapted to olfaction in their new environment — an intriguing question because the sense of smell needs to operate under very different conditions in air compared to water.

	Crab - LoveToKnow 1911 (Site not responding. Last check: 2007-10-02)
		Most crabs live in the sea, and even the land-crabs, which are abundant in tropical countries, nearly all visit the sea occasionally and pass through their early stages in it.
		As a rule, crabs breathe by gills, which are lodged in a pair of cavities at the sides of the carapace, but in the true land-crabs the cavities become enlarged and modified so as to act as lungs for breathing air.
		Some crabs live among corals, and one species at least gives rise to hollow swellings on the branches of a coral like the "galls" which are formed on plants by certain insects.

		A crab's mouth is flanked by six pairs of feeding appendages that the crab uses to crush food and feed itself.
		Hermit crabs and robber crabs walk forward for the most part, but the true crabs are experts at walking or running sideways, often at lightening speed.

		It is a derived hermit crab which is known for its ability to crack coconuts with its strong pincers in order to eat the contents.
		It is sometimes called the robber crab or palm thief (in German, Palmendieb), because some coconut crabs steal shiny items such as pots and silverware from houses and tents.
		Another name is the terrestrial hermit crab, due to the use of shells by the young animals (although terrestrial hermit crab also applies to a number of other hermit crabs - see Australian land hermit crab).

		The robber crab, which is descended from marine crabs, had to develop a new way of smelling things when it moved out of the sea and on to land.
		Robber crabs (Birgus latro) are the world's largest land-dwelling arthropods, reaching a length of more than half a metre and a weight of 4kg.
		By placing baits around the island containing familiar foods such as dead red crabs and coconut flesh, as well as empty control baits, the scientists were able to confirm the crabs' famous ability detect odours at long distances.

		A new study has shown that land-living crabs, descended from marine ancestors, have re-invented key aspects of the insect nose through evolution in order to be able to smell in their air-filled, land-based environment.
		A question not previously addressed is how the robber crabs have adapted to be able to smell in their new environment — an intriguing question because the sense of smell needs to operate under very different conditions in air compared to water.
		The "insect nose" of the robber crab is a striking example of convergent evolution, illustrating how similar needs of distantly related organisms may cause similar end results.

	Crab Biology
		The terrestrial hermit crabs and a few true land crabs of the family Gecarcinidae are the only decapod crustaceans (shrimps, lobsters, crabs, etc.) that have successfully migrated from the sea directly to dry land.
		When the hermit crabs are active and encountering each other in their travels, they often make croaking sounds, but the source of this apparent means of communication is still uncertain.
		The hermit crabs on Curacao first migrate from island areas to a locations near, but not necessarily on, the coast, where there are sources of fresh water with which to dilute the shell water.

	Coconut Crab – in need for recognition
		The largest crab apparently got its first name from its favorite food, the coconut and its second name “Robber crab” because of its ability to rob people off shiny goods such as tin cans, pots, spoons, cups, so be ware when camping in a Robber’s territory.
		Coconut crab is a very gentle non-aggressive animal, it surrenders itself to hunters in the night to be caught, tied and bagged for the market.
		The crab has developed a sense of comfort to live off the land by developing climbing skills to fetch food from tree tops, digging skills to burrow underground and into tree trunks to hide, possess gills to survive when drawn, lay its eggs or to drink a little saltwater to maintain its body salt.

		They are well-demanded by a number of different-sized hermit crabs, which crawl into snail shells to protect their soft body parts from potential predators.
