What is the study of crustaceans?
Malacostracology (mala-"soft", costraca-"shell", -ology - "study of") is the formal branch of Zoology and Marine Science relating to the study of animals anatomically united by a bauplan, comprising of 20 body segments divided into head, thorax and abdomen regions, also known as "crustaceans". The focus of Malacostracology includes crab, lobster, shrimp, krill, crayfish, scuds, mantis shrimp, and false crustaceans - such as hermit crab, king crab, horseshoe crab and porcelain crab. The term "Malacostraca" refers to the same class of animals under biological taxonomy.
