There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. [citation needed] Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or ...
Experimental data suggest that a two-stage mechanism is required. In the first, a light-emitting substance (called "luciferin") is reduced by a soluble reductase enzyme at the expense of NAD(P)H. In the second stage, reduced luciferin is oxidized by an insoluble luciferase that releases the energy in the form of bluish-green light.
The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. It is absent in many fish families, but found in nine of the 31 euteleostean orders ( Percopsiformes , Myctophiformes , Aulopiformes , Stomiiformes , Salmoniformes , Osmeriformes , Characiformes , Siluriformes and Argentiniformes ...
Most fishes have one dorsal fin, but some fishes have two or three. In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure. The two to three bones that support the dorsal fin are called the proximal, middle, and distal pterygiophores. In spinous fins, the distal ...

White fish (Atlantic cod) White fish fillet (halibut – on top) contrasted with an oily fish fillet (salmon – at bottom)Whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly Atlantic cod (Gadus morhua), whiting (Merluccius bilinearis), haddock (Melanogrammus aeglefinus), hake (Urophycis), and pollock (Pollachius), among others.
Hydnum repandum, commonly known as the sweet tooth, pig's trotter, [7] wood hedgehog or hedgehog mushroom, is a basidiomycete fungus of the family Hydnaceae. First described by Carl Linnaeus in 1753, it is the type species of the genus Hydnum .
A commonly eaten mushroom is the white mushroom (Agaricus bisporus). In a 100-gram (3 + 1 ⁄ 2-ounce) reference serving, Agaricus mushrooms provide 92 kilojoules (22 kilocalories) of food energy and are 92% water, 3% carbohydrates, 3% protein, and 0.3% fat.
