>For the band, see Seafood (band). Seafood is any sea animal that is served as food or is suitable for eating. This usually includes sea water animals, such as fish and shellfish (including mollusks, and crustaceans). By extension, the term seafood is also applied to similar animals from fresh water. These aquatic animals are also collectively referred to as seafood. See more at Wikipedia.org...

>For other uses, see Crab (disambiguation). DromiaceaRaninoidaHeterotremataThoracotremata The term crab is often applied to several different groups of short (nose to tail) decapods with thick exoskeletons, but only members of the Brachyura are true crabs; other taxa, such as hermit crabs, porcelain crabs, king crabs, and horseshoe crabs are, despite superficial similarities, not crabs at all. Hermit crabs, king crabs and porcelain crabs belong to the Anomala and can be distinguished from true crabs by counting the legs - in Anomala, the last pair of pereiopods (walking legs) is hidden inside the carapace and so only four pairs are visible (counting the claws), whereas uninjured true crabs always have five visible pairs.
