'''Decapodiformes''' is a [[superorder]] of [[Cephalopoda]] comprising all cephalopod species with ten [[Cephalopod limb|limbs]], specifically eight short arms and two long tentacles. It is hypothesized that the ancestral [[coleoid]] had five identical pairs of limbs, and that one branch of descendants evolved a modified arm pair IV to become the Decapodiformes, while another branch of descendants evolved and then eventually lost its arm pair II, becoming the [[Octopodiformes]].
