🔬 物种简介
印鱼头顶有特化的椭圆形吸盘（由第一背鳍演化），用于吸附在鲨鱼、海龟、蝠鲼等大型生物身上，搭乘"顺风车"的同时取食宿主剩余的食物碎屑。这种关系是偏利共生还是互利共生仍有争议——有观点认为印鱼还能清理宿主的寄生虫。
Wikipedia
The remora, sometimes called suckerfish or sharksucker, is any of a family (Echeneidae) of ray-finned fish in the order Carangiformes. Depending on species, they grow to 30–110 cm (12–43 in) long. Their distinctive first dorsal fins take the form of a modified oval, sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals. The disk is made up of stout, flexible membranes that can be raised and lowered to generate suction. By sliding backward, the remora can increase the suction, or it can release itself by swimming forward. Remoras sometimes attach to small boats, and have been observed attaching to divers as well. They swim well on their own, with a sinuous, or curved, motion.
