Mictyris Livingstonei
''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]   |

New Scientist
''New Scientist'' is a magazine covering all aspects of science and technology. Based in London, it publishes weekly English-language editions in the United Kingdom, the United States and Australia. An editorially separate organisation publishes a monthly Dutch-language edition. First published on 22 November 1956, ''New Scientist'' has been available in online form since 1996. Sold in retail outlets (paper edition) and on subscription (paper and/or online), the magazine covers news, features, reviews and commentary on science, technology and their implications. ''New Scientist'' also publishes speculative articles, ranging from the technical to the philosophical. ''New Scientist'' was acquired by Daily Mail and General Trust (DMGT) in March 2021. History Ownership The magazine was founded in 1956 by Tom Margerison, Max Raison and Nicholas Harrison as ''The New Scientist'', with Issue 1 on 22 November 1956, priced at one shilling (a twentieth of a pound in pre-decimal UK cu ...

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 ...

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).

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 ...
