crab
a sort of wooden pillar, whose lower end, being let down through a shipâs decks, rests upon a socket like the capstern; and having in its upper-end three or four holes, at different heights, throâ the middle of it, above one another, into which long bars are thrust, whose length is nearly equal to the breadth of the deck. It is employed to wind in the cable, or to purchase any other weighty matter which requires a great mechanical power. This differs from a capstern, as not being furnished with a drum-head, and by having the bars to go intirely through it, reaching from one side of the deck to the other; whereas those of the capstern, which are superior in number, reach only about eight inches or a foot into the drum-head, according to the size thereof. This machine is represented in plate II. by fig. 10, and 13. See also CAPSTERN.

Also, a portable wooden or cast-iron machine, fitted with wheels and pinions similar to those of a winch, of use in loading and discharging timber-vessels, &c.--The crab with three claws, is used to launch ships, and to heave them into the dock, or off the key.--To catch a crab.

Crabs are crustaceans. They have a very short tail. A crab's tail is folded under its body. It might not be visible at all, unless you turn the crab around. Usually they have a very hard exoskeleton. This means they are well protected against predators. Crabs are armed with a single pair of claws. Crabs can be found in all the oceans. Some crabs also live in fresh water, or live completely on land. The smallest known crab is the pea crab. Some are only a few millimeters wide. The biggest known crab is the Japanese spider crab. It lives in the Pacific, between 300 and 400 metres deep. The crabs that were found had a leg span of up to 4 metres, were up to 37 centimetres large, and had a weight of up to 20 kilograms.
Crabs are omnivores, they eat anything they find. Most often this is algae. It might also be molluscs, other crustaceans, worms, fungi and bacteria.
The closest relatives of the crabs are anomurans, a crustacean group which includes animals such as hermit crabs, king crabs and squat lobsters. They look a lot like crabs and many have the word "crab" in their name, but are not true crabs. Anomurans can be told apart by the number of legs: crabs have ten legs, including claws, while the last pair of an anomuran's legs is hidden inside the shell, so that only eight legs are visible.
