海七鳃鳗(英语:Petromyzon marinus)又称海八目鳗,是七鳃鳗目七鳃鳗科海七鳃鳗属唯一的一种。

外观

[编辑]

体性似鳗鱼,不具有成对鳍,具有七对鳃,故称七鳃鳗。口部如圆盘状,具角质化的牙齿。体长可达 120 cm(47英寸),体重则可接近2.3千克(5.1磅)[4]

分布

[编辑]

分布于大西洋北部与西部北美洲欧洲沿岸、地中海西部、黑海五大湖[1],曾发现于 4,000 米的深海中,可忍受 1 ~ 20 °C的水温[4]。产卵于欧洲北美的河流中。

习性

[编辑]

为寄生鱼类,用圆盘状的口紧紧吸附在猎物身上,用角质齿刺破猎物的表皮,吸取猎物的淋巴液。海七鳃鳗为溯河洄游类型的鱼类,在繁殖期时从海洋或湖游至河流中产卵,挖洞筑巢,产下卵后便死去。幼鳗以沙中的浮游生物为食[1],成年后便以吸血寄生为主[5],一些幼鳗在进到海洋之前便已开始转以吸血维生[6]
