The Mola mola (翻车鱼) is the world’s largest known bony fish. The species is native to tropical and temperate waters around the globe, and resembles a giant fish head with a tail. Rather than having a tail fin, like most fish, the Mola mola’s main body is flattened. In fact, its height is often equal to its length, which is unusual in fish. It can grow to 10-20 feet in length and height and weigh in at an average of 2,000 pounds.
Its specific name, mola, is Latin for “millstone”, which the fish resembles because of its grey colour, rough texture (肌理), and rounded body. Its common English name, sunfish, refers to the animal’s habit of sunbathing at the surface of the water. The Dutch-, Portuguese-, French-, Catalan-, Spanish-, Italian-, Russian-, and German-language names mean “moon fish”, in reference to its rounded shape. In Polish it is named Samoglow, meaning “head alone”, because it has no true tail. The Chinese translation of its academic name is fan-che-yu.
Its diet is extremely varied but nutrient-poor, consisting mainly of jellyfish. In order to consume enough daily nutrients, it must travel through a wide range of oceanic depths in search of its food. It has a beaked(喙状嘴的) mouth that does not totally close, so it chews its food in several stages.
Its thick skin is covered in a dense layer of mucus (粘液), which is host to many kinds of parasites(寄生虫). To try and rid itself of these uninvited guests, it will often float on its side near the surface of the water, inviting birds to feast on the parasites. Similarly, it will sometimes launch its considerable body up to ten feet out of the water before crashing back down in an effort to remove some of the parasites. With its habit of floating near the surface, it often runs the risk of being hit by boats. Finally, smaller Mola molas are sometimes subject to attack by sea lions.
