Most species within the order Tetraodontiformes range in size from approximately 8 to 60 cm (3 to 24 inches) in length.1

While this size range encompasses the majority of the order, there are notable exceptions. For instance, the mola, or ocean sunfish (Mola mola), can reach lengths of more than 3 metres (10 feet). Other members of the family Molidae also reach enormous sizes, with some individuals growing up to 3.3 metres (11 feet) in length and weighing as much as 1,900 kg (4,000 pounds).12
