What functional meaning is conveyed by the order Decapoda for lobsters?
Answer
Ten-footed
The classification of the lobster within the order *Decapoda* provides direct insight into a fundamental aspect of its physical structure. The term Decapoda is derived from Greek roots meaning 'ten-footed.' This designation accurately reflects the anatomy of these crustaceans, specifically that they possess ten legs extending from the thorax region of their body. These ten limbs are functionally categorized; three pairs are modified into claws, including the large chelae, while the remaining eight limbs are the pereiopods dedicated primarily to locomotion along the benthic zone.
