Mictyris
''Mictyris'' is a genus of brightly coloured crabs, placed in its own taxonomical family, the Mictyridae. 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. They congregate during low tide, and bury themselves in the sand during high tide or whenever they are threatened. This is done in wet sand, and they dig in a corkscrew pattern, leaving many small round pellets of sand behind them. Species The genus contains eight species: The predictable behaviour of these crabs has led them to be used in experiments in a form of billiard ball computer A billiard-ball computer, a type of conservative logic circuit, is an idealized model of a reversible mechanical computer based on Newtonian dynamics, proposed in 1982 by Edward Fredkin and Tommaso Toffoli.

Mictyris Longicarpus
''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". Adults are across, white, with blue on their backs, and hold their claws vertically. They feed on detritus in the sand, leaving rounded pellets of discarded sand behind them. The males may form into large "armies" which traverse the beach at low tide, before the crabs dig into the sand to wait for the next low tide. Description ''Mictyris longicarpus'' is nearly spherical, with an upright body. Its carapace is powder blue, with the rest of the body being white except for purple patches on the joints of the legs. The chelae (claws) are slim and curve downwards, and are held vertically in front of the crab. Given the crab's upright posture, the eyestalks are short. The body is up to across, or "about the size of a cherry". Distribution '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mictyris Brevidactylus
''Mictyris brevidactylus'' is a species of crab found in Japan, China (including the type location, Hong Kong), Taiwan, Singapore, and parts of Indonesia (Karakelong, Bawean and Ambon Island). The adults have a light-blue carapace and scarlet-jointed legs, while juveniles are yellowish-brown. ''M. brevidactylus'' is gregarious and burrows into the sand when disturbed, in a corkscrew A corkscrew is a tool for drawing corks from wine bottles and other household bottles that may be sealed with corks.

Mictyris Guinotae
''Mictyris guinotae'' is a species of soldier crab of genus '' Mictyris'', endemic to the Ryukyu Islands of Japan. They were named after Danièle Guinot, a professor at the Muséum national d'histoire naturelle in France, and were first treated as a separate species in a tribute volume to Guinot. Description ''Mictyris guinotae'' has a well-defined subglobular body, slightly less wide than long, a relatively smooth carapace, and long thin legs. They range in color from pale to dark blue, with occasional pale pink variants; they tend to be darker when they are younger and lighter when they are older. The adult male specimens observed had carapaces between 8 and 16 mm long; adult female carapace lengths ranged from 6 to 14 mm. Behavior These crabs live in colonies of hundreds to hundreds of thousands of individuals, in flat lagoon areas of the islands they inhabit. In times of low tide, they form large swarms or "armies" that cross the lagoons ''en masse'', while at hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

They live in large groups, so are commonly called soldier crabs. Adults are across and similarly tall, and are coloured blue to blue-grey. ''Mictyris platycheles'' gets its food by picking up balls of sands and putting it in its mouth, which filters out the food particles (detritus).

Billiard Ball Computer
A billiard-ball computer, a type of conservative logic circuit, is an idealized model of a reversible mechanical computer based on Newtonian dynamics, proposed in 1982 by Edward Fredkin and Tommaso Toffoli. Instead of using electronic signals like a conventional computer, it relies on the motion of spherical billiard balls in a friction-free environment made of buffers against which the balls bounce perfectly. It was devised to investigate the relation between computation and reversible processes in physics. Simulating circuits with billiard balls This model can be used to simulate Boolean circuits in which the wires of the circuit correspond to paths on which one of the balls may travel, the signal on a wire is encoded by the presence or absence of a ball on that path, and the gates of the circuit are simulated by collisions of balls at points where their paths cross. In particular, it is possible to set up the paths of the balls and the buffers around them to form a reversibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
