Definition

Noun: 1. A former taxonomic group of crustaceans: In historical biological classification systems, "Schizopoda" was a division or order of the class Malacostraca. It included shrimp-like crustaceans characterized by having a carapace that does not completely cover the thorax and biramous (forked) thoracic limbs. This group is no longer used in modern scientific taxonomy.
