"True crabsare decapod crustaceans of the infraorder Brachyura," (http://en.wikipedia.org/wiki/Crab) and "many varieties of shellfish (crustaceans in particular) are actually closely related to insects and arachnids" (http://en.wikipedia.org/wiki/Shellfish).
Crabs are not related to insects. Crabs belong to the phylum Arthropoda, like insects, but they are classified under the subphylum Crustacea, while insects belong to the subphylum Hexapoda. They have different body structures, with crabs having a hard exoskeleton and jointed legs, while insects have six legs and often wings.
