The genome of the largest bony fish, ocean sunfish (Mola mola), provides insights into its fast growth rate

摘要

Background The ocean sunfish ( Mola mola ), which can grow up to a length of 2.7 m and weigh 2.3 tons, is the world’s largest bony fish. It has an extremely fast growth rate and its endoskeleton is mainly composed of cartilage. Another unique feature of the sunfish is its lack of a caudal fin, which is replaced by a broad and stiff lobe that results in the characteristic truncated appearance of the fish.
