Decapodiformes Leach 1817

Brief Summary

    Decapodiformes: Brief Summary
    provided by wikipedia

    Decapodiformes is a superorder of Cephalopoda, which includes all species with ten limbs; the name derives from the Greek word meaning ten feet. The ten limbs are divided into 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.

    The Decapodiformes include:

    ?Order †Boletzkyida Clade †Belemnoidea Order Spirulida: ram's horn squid Order Sepiida: cuttlefish Order Sepiolida: pygmy, bobtail and bottletail squid Order Myopsida: coastal squid Order Oegopsida: neritic squid
