Sepiida is an order of ten-armed cephalopods. This order contains the following superfamilies and families:
Taxonomy Order Sepiida Superfamily Sepioidea Family Anomalosaepiidae Yancey & Garvie, 2011 Family Belosaepiidae Dixon, 1850 Family Sepiidae W.E. Leach, 1817 Superfamily VasseurioideaPonder, W. F.; Lindberg, D. R. (2020). Biology and evolution of the Mollusca. In: Ponder W.F., Lindberg D.R. & Ponder J.M. vol. 2. CRC Press, Boca Raton. xx + 870 pp. Family Vasseuriidae Family Belosepiellidae
The bobtail or bottletail squid (order Sepiolida) were previously placed within this order as the suborder Sepiolina (sister to a suborder Sepiina), but they are now understood to form their own distinct order; their exact relationship with the cuttlefish is currently in flux, but they have not been recovered close to Sepiida in recent phylogenetic analyses (see Decapodiformes#Taxonomy).
