The Life of Animals | Sunfish | The tail fin of the sunfish is replaced by a rounded clavus, cut the creation of the various bodies. The ribs are small, fan-shaped, while the dorsal fin and the anal fin are lengthened, which is often high to fish as long. Although the sunfish came from bony ancestors, the skeleton contains largely cartilaginous tissues, which are lighter than bone, so that you grow the sizes impractical for other bony fish. The sunfish lacks a swim bladder. Sunfish for adults ranges from brown to gray silver or white, with a variety of models, mottled skin, some of these models may be specific to the region. Mola mola also shows the ability of the skin color varies from light to dark, especially if they are attacked.
More than 40 species of parasites in the skin and are internally, motivating the fish to seek relief in a number of ways. In temperate regions, the fields of algae float harbor cleaner wrasses and other fish, visit the parasites from the skin to remove sunfish. In the tropics, the mola cleaning recruits the help of reef fish. By basking on its side at the surface, the sunfish also allows that the birds feed on skin parasites. Sunfish were injury, reported to clean the surface by more than three lengths, possibly as a further attempt to remove parasites. In the course of its evolution disappeared the caudal fin (tail) of the sunfish, by a lumpy pseudo-tail, which are replaced clavus.
Is without a queue for providing forward thrust for forward motion and with only small pectoral fins, Mola Mola is based on his long, thin dorsal and anal fins for propulsion, on the same forward these fins from side to side. Sunfish often swim near the surface and its prominent dorsal fins are sometimes mistaken for sharks. Sharks, like most fish swim by the side of the tail stops while the dorsal fin. The ocean sunfish, but can identify changes in the dorsal fin and anal fin function in rowing motion used Although research suggests that early sunfish pulled drift with ocean currents, especially, people were swimming are 26 km in one day, for a maximum speed of 3.2 kilometers per hour Sunfish pelagic and swim at depths of up to 600 meters (2,000 feet) .
Sunfish are usually found in hot water at 10 ° C (50 ° F) for long periods in a water temperature of 12 spent ° C (54 ° F) or lower, disorientation and death. Sunfish are usually alone, but sometimes in pairs or in larger groups, while cleaning. Sea lions seem sunfish hunt for sport, breaking fins, move around your body, and then just let the fish still alive, but not at the bottom of the sea to die. The mating practices of the sunfish are poorly understood, but spawning areas have been proposed in the North Atlantic, South Atlantic, North Pacific, South Pacific and Indian Oceans. Sunfish eggs are released into the water and were fertilized by the sperm. Sunfish newly hatched larvae are only 2.5 mm (0.098 in) in length. Many millions of times their original size before reaching adult proportions Sunfish fry, atypical with large pectoral fins, a tail fin and body spines of adult sunfish, miniature pufferfish, resemble their close relatives. Young sunfish school for protection, but this behavior is abandoned as they grow.
Despite their size, oceansunfish are docile, and pose no threat to human divers. Injuries from sunfish are rare, although there was a small risk sunfish great leap out of the water in a boat, in a case raised a child from his boat when a sunfish leaped upon him. All parts of the sunfish used in the kitchen, ground, around internal organs. When the body does not contain toxins, marketing and distribution of sunfish meat in the European Union in the framework of Regulation (EC) No prohibited. Sunfish but often accidentally in fishing with drift nets, which captured a share of almost 30% of the total catch of swordfish with driftnets in the world of work in California. The detection rate is even higher for the Mediterranean swordfish industry, with 71% and 90% of the total catch sunfish. Bycatch of fishing and the destruction of ocean sunfish are unregulated worldwide. Many areas of sunfish biology remain poorly understood, and research efforts are varied, including aerial photographs of mola populations, satellite monitoring with pop-off satellite tags, the genetic analysis of tissue samples, and the collection of amateur sighting data. Recent studies show a decrease in sunfish populations that may be caused by more frequent bycatch and the increasing popularity of sunfish in the human diet,
