What are crabs?

Answer 1

A crab stick is a side dish common in Australian fish and chip eateries.

It is essentially crab meat (although in many cases it is processed, thereby retaining little of its nutritional value), which has been battered and deep fried.

Answer 2

Several kinds of crabs, some are crustaceans , others are pubic lice. They feed on blood. That's why you're fun parts can be itchy. They are called crabs because the adults look like small crabs. They can survive 24 hours without feeding and can live in bedding, clothing and sleeping bags. Females have babies that attach to the hairs(can be any body hair) and must be shaved or combed with a nit comb or very fine comb to remove the little bastards The other kinds of crabs are all members of Phylum Arthropoda, Subphlyum Crustacea, Class Malacostraca, and Order Decapoda. They are usually covered by a hard shell (exoskeleton) and possess ten legs, the first two of which are modified into pinchers (chelae). Crabs are distributed between two infraorders, the Brachyura and the Anomura. The Brachyura are the true crabs and includes most of the crabs we eat and most of the crabs you might sea on the seashore. If you turn the crab over, you will see that the brachyuran crabs all have symmetrical abdomens. The Anomurans include king crabs, hermit crabs, and a variety of other crabs that all possess an asymmetrical abdomen.
rabs are related to lobsters and shrimps. However, they have evolved so that they can walk or run sideways, as well as burrow and swim. The body is covered by a chitinous shell called a carapace. A crabs abdomen has become fairly reduced and is tucked under the body. "This reduction is greatest among the true crabs, which lack the flaplike tail of the hermit crabs and their allies; instead, the abdomen serves as a brood pouch for the eggs. A crab's segmented body has several pairs of appendages, of which usually five pairs serve as walking legs and two as sensory antennae."(1) The pincers, called chelae, are located on the front legs ans are used for fighting, display, and feeding. Crabs can possess fairly complicated nervous systems and are considered to be more advanced. They can live in more extreme areas because of their ability to adapt well to the changing environment. Crabs can see fairly well with their compound eyes; their senses of smell and taste are also more advanced which helps them to find food and mates easier. "Reproductive and social behavior sometimes include complex mating rituals and communication techniques such as drumming or waving the pincers. Crabs tend to be aggressive toward one another, and the males often fight to gain access to the females."(2)
