As with L030, the dorsal and ~TildeLink() are joined together to a large single fin. anglerfishes
Nowadays they are mainly extinct, with only eight living species. Salmoniformes -

Define adipose fin.
Vent: The vent removes waste and extra water.
On the catfish and bullheads, barbels are thought to be a sensory organ to help track down prey or food. Usually found in depths between 180 and 640 m. Lampriformes -

Adipose fin: A soft, fleshy fin found on the back behind the dorsal fin and just in front of the caudal fin. Pelvic fins, when present, inserted below or in front of pectorals (thoracic or jugular, rarely behind in Macrouridae) with up to 11 rays; no true spines in the fins; most with long dorsal and anal fins; scales usually cycloid, rarely ctenoid; premaxilla forms the entire margin of upper jaw, protractile in some; ectopterygoid toothless; orbitosphenoid and basisphenoid absent; branchiostegal rays 6-8; posterior vertebral reduction results in posterior dorsal and anal pterygiophores exceeding the number of caudal vertebrae; swim bladder without pneumatic duct (the swim bladder is absent in Melanonus and Squalogadus). What is what? Clupeiformes -
Today the adipose fin is present in eight groups of extant fishes including the catfishes (Siluriformes), the salmonids (Salmoniformes), and the lanternfish (Myctophiformes). Cyprinodontiformes -
Pelvic fins when present, inserted at level of preopercle or farther anterior (mental or jugular), zero to two soft rays in each, and occasionally with a spine; base of dorsal and anal fins long, extending to and usually joined with caudal fin; nostrils paired on each side; dorsal and anal fin pterygiophores more numerous than adjacent vertebrae (the ratio being about 1.8:1).
Body and jaws elongate; mouth with needlelike teeth; abbreviated heterocercal tail; heavy ganoid scales, about 50-65 along lateral line; dorsal fin far back, with few rays; three branchiostegal rays; interoperculum absent; two or more supratemporal bones on each side; maxilla small and immobile; supramaxilla absent; myodome absent; vomer paired; swim bladder vascularized (thus permitting aerial respiration); vertebrae opisthocoelous (anterior end convex, posterior end concave, as in some reptiles and unlike all other fish except the blenny Andamia. Maximum length about 90 cm. The consensus is to consider that they are close to Atherinids, Gasterosteids, Synbranchids, Elassomatids in an unresolved polychotomy. All rights reserved.
No fish from which the entire adipose fin was clipped exhibited regeneration. Not all fish have adipose fins, but salmon and trout do. I mean they are scaly little buggers that swim in the water, and some taste pretty good. It is located between the dorsal fin and the tail.
Maximum length is 38 cm. Hearing: Fish have ears but not external ear openings like humans do. This time they consider 1906 catfish species, and compared the presence of the adipose fin to the habitat in which the species lived. Dorsal fin absent. It is not pictured here, but fish also have a liver.

They found that for species in moving waters (streams and rivers), an adipose fin was more often present than for species in low-flow environments, such as lakes. Enrolling in a course lets you earn progress by passing quizzes and exams.
Also known from the lower and middle Zambezi, Pungwe, lower Save, and throughout the Congo system. Scales: Scales protect the fish from injury. Ateleopodiformes -
courses that prepare you to earn Ostariophysan - Ostariophysan - Fin spines and adipose fin: Ostariophysans possess segmented, branched, flexible, soft rays in the fins, unlike the stiff spines of perchlike fishes.

It is also the outlet for eggs or milt (sperm) during spawning. Caudal Fin: The caudal fin moves, propels or pushes the fish through the water.
Its purpose is unknown. sawbellies

Caudal fin reduced, united with the long anal fin; pelvic fin of adults with single ray on throat (young specimens and Guentherus gave several rays, and the pelvics of the latter are behind the pectorals); dorsal fin with 3-13 rays; skeleton largely cartilaginous; snout bilbous; branchiostegal rays 7.
The study may also have implications for the common fisheries practice of clipping off or tagging the adipose fin to differentiate hatchery-grown fish from wild fish. Gadiformes -
