章魚(短章魚,長章魚,水章魚)

章魚(Octopus):為章魚科26屬252種海洋軟體動物的通稱。為頭足綱最大科,可分為深海多足蛸亞科(Bathypolypodinae)、愛爾斗蛸亞科(Eledoninae)、谷蛸亞科(Graneledoninae)和蛸亞科(Octopodinae)。體卵形或卵圓形,肌肉強健,外套腔開口窄,體表一般不具水孔。腕吸盤1列或2列。雄性左側或右側第3腕莖化,腕腹緣具精溝,末端具勺狀舌葉;莖化腕不能自斷。漏斗外套鎖退化。具1對退化針狀內殼或無內殼。若具齒舌,齒舌側齒一般單尖。胃和盲腸位于消化腺后部。

該科是重要的商業性頭足類,中國南部沿海的真蛸(普通章魚)和北部沿海的短蛸均有一定產量。蛸的干制品稱“八蛸干”或“章魚干”,除食用外,在醫藥上尚有補血益氣、收斂生肌的作用。

為溫帶性軟體動物,生活在水下,適應水溫不能低于7℃,海水比重1.021最為適宜,低鹽度的環境會死亡。能攝食大型動物性浮游生物而成長。廣泛分布于世界各大洋的熱帶及溫帶海域。
