The ocean sunfish (Mola mola), also known as the common mola, is one of the largest bony fish in the world. It is the type species of the genus Mola, and one of five extant species in the family Molidae. [6] [7] It was once misidentified as the heaviest bony fish, which was actually a different and closely related species of sunfish, Mola ...
Sunfish skeleton photographed by Lewis Carroll. Molidae have the fewest vertebrae of any fish, with only 16 in Mola mola. The axial musculature, caudal and pelvic fins are completely lost during development, and most of their skeleton is made of cartilage. They also lack swim bladders. No bony plates occur in the skin, which is, however, thick ...
The giant sunfish or bumphead sunfish (Mola alexandrini), [3] (also known as the Ramsay's sunfish, southern sunfish, southern ocean sunfish, short sunfish or bump-head sunfish in various parts of the world), [4] is a fish belonging to the family Molidae.
The mola is the heaviest of all the bony fish, with large specimens reaching 14 ft (4.3 m) vertically and 10 ft (3.0 m) horizontally, and weighing over 6,000 lb (2,700 kg). [3] Sharks and rays can be heavier, but they are cartilaginous fish. Mola are found in temperate and tropical oceans around the world.
There are three extant species under the genus Mola: Mola mola, Mola alexandrini, and Mola tecta. [7] Mola mola is the most common known ocean sunfish and was found in 1758 and Mola alexandrini (also called Mola ramsayi) was found 81 years afterward, in 1839. [7] [1] In comparison to its two relatives, Mola tecta was found recently in 2014. [8]
A giant species of fish that was first discovered seven years ago washed ashore in Oregon last week, according to marine biologists who study the animal.
Gillnets are designed to catch fish of a certain size when the fish’s head passes through the net, but the body gets stuck. Theoretically, larger- and smaller-sized fish would either pass ...
Fish bone is any bony tissue in a fish, although in common usage the term refers specifically to delicate parts of the non-vertebral skeleton of such as ribs, fin spines and intramuscular bones. Not all fish have fish bones in this sense; for instance, eels and anglerfish do not possess bones other than the cranium and the vertebrae.
