Overview
Brief Summary
Introduction
This genus is probably the most speciose in the Cephalopoda. Because of the great variability among species, the genus is best defined by the other two genera; that is, Sepia is the sepiid that doesn't have the major characters that define Metasepia and Sepiella.
Brief diagnosis:
- without pore at posterior end of mantle.
- with cuttlebone length approximately the same as mantle length.
