The most popular crab-fishing time occurs between October and January. The allocated time for a season continued to shrink – at one point a red crab season was only four days long. After 2005, each boat was given a quota based on their catch from previous years and how many crabs are available to catch.
Declawing of crabs is the process whereby one or both claws of a crab are manually detached before the return of the live crab to the water, as practiced in the fishing industry worldwide. Crabs commonly have the ability to regenerate lost limbs after a period of time, and thus declawing is viewed as a potentially more sustainable method of ...

[11] Mature adults may have a carapace width of up to about 25 cm and weigh up to ...
Some crab-shaped species have evolved away from the crab form in a process called decarcinisation. Decarcinisation, or the loss of the crab-like body, has occurred multiple times in both Brachyura and Anomura. [25] [26] However, there are varying degrees of carcinisation and decarcinisation. Thus, not all species can necessarily be distinctly ...
Hermit crab species range in size and shape, from species only a few millimeters long to Coenobita brevimanus (Indos Crab), which can approach the size of a coconut and live 12–70 years. The shell-less hermit crab Birgus latro (coconut crab) is the world's largest terrestrial invertebrate .
