More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Shrimp definition is - any of numerous mostly small and marine decapod crustaceans (suborders Dendrobranchiata and Pleocyemata) having a slender elongated body, a compressed abdomen, and a long spiny rostrum and including some (especially family Penaeidae) that are commercially important as food; also : a small crustacean (such as an amphipod or a branchiopod) resembling the true shrimp.

The female dwarf shrimp use them … 0 Comments Add a Comment. Under a 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. Shrimp: a small free-swimming crustacean with an elongated body, typically marine and frequently of commercial importance as food. Shrimp are invertebrates with a hard exoskeleton. [66] In 1583, the Dutch banned shrimp trawling in estuaries. "On this basis, taxonomic classifications now divide the order Decapoda into the two suborders: Dendrobranchiata for the largest shrimp clade, and Pleocyemata for all other decapods.
