Decapodiformes
Also known as Decabrachia
Decapodiformes is a superorder of Cephalopoda comprising all cephalopod species with ten 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.

十腕總目（學名：Decapodiformes），俗稱“烏賊”，古稱烏鰂，是一種頭足綱蛸亞綱新蛸下綱之下的一類軟體動物，所有烏賊都可以噴墨。烏賊類可以大致概括本類多數動物。與蛸亞綱的其他分類一樣，十腕總目的所有物種都同樣有10隻觸手，但其第四對觸手演變成為了有吸盤的長觸鬚。海鮮食物中常見的的魷魚、花枝（墨魚和管魷目）、鎖管等都屬於這個總目

Decapodiformes is a superorder of Cephalopoda comprising all cephalopod species with ten 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.
==Taxonomy== The following orders are recognised in the superorder Decapodiformes: Bathyteuthida †Belemnitida †Diplobelida Idiosepida – pygmy squid Myopsida – coastal squid Oegopsida – neritic squid Sepiida – cuttlefish Sepiolida – bobtail and bottletail squid Spirulida – ram's horn squid
