The term shrimp is used to refer to some decapod crustaceans, although the exact animals covered can vary.

Used broadly, it may cover any of the groups with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata.

In some fields, however, the term is used more narrowly, and may be restricted to Caridea, to smaller species of either group, or to only the marine species.

Under the broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails (abdomens), long whiskers (antennae), and slender legs.

Any small crustacean which resembles a shrimp tends to be called one.

They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly.

Crabs and lobsters have strong walking legs, whereas shrimp have thin fragile legs which they use primarily for perching.

Lobsters comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans.

They have long bodies with muscular tails, and live in crevices or burrows on the sea floor.

Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others.

Highly prized as seafood, lobsters are economically important, and are often one of the most profitable commodities in coastal areas they populate.

Commercially important species include two species of Homarus from the northern Atlantic Ocean, and scampi – the Northern Hemisphere genus Nephrops and the Southern Hemisphere genus Metanephrops.

Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the family Nephropidae.

Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no claws (chelae), or to squat lobsters.

The closest living relatives of clawed lobsters are the reef lobsters and the three families of freshwater crayfish.

Salmon is the common name for several species of ray-finned fish in the family Salmonidae.

Other fish in the same family include trout, char, grayling and whitefish.

Salmon are native to tributaries of the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus).

Many species of salmon have been introduced into non-native environments such as the Great Lakes of North America and Patagonia in South America.

Salmon are intensively farmed in many parts of the world.

Seafood is any form of sea life regarded as food by humans.

Seafood prominently includes fish and shellfish.

A fish is any member of a group of animals that consist of all gill-bearing aquatic craniate animals that lack limbs with digits.

They form a sister group to the tunicates, together forming the olfactores.

Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups.

Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well.

However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry).

Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology.

The traditional term pisces (also ichthyes) is considered a , but not a phylogenetic classification.
