In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. 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]
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 ...
The young mushroom develops a veil, which is lost as the mushroom grows to maturity. [1] The mushroom's stipe appears to be quite strong, and is anchored up to 1.6 feet (0.5 m) deep in sediment, in order to stand up to the fast-moving river currents where it is primarily found. [1] The stipe is covered in thin hair like structures. [1]
"Cephalic fins": The "horns" of manta rays and their relatives, sometimes called cephalic fins, are actually a modification of the anterior portion of the pectoral fin. Pelvic/Ventral fins: Found in pairs on each side ventrally below the pectoral fins, pelvic fins are homologous to the hindlimbs of tetrapods. They assist the fish in going up or ...
The whitefin trevally is silver, with a blue to green dorsal surface, becoming silvery white below. The soft dorsal and anal fins are dusky yellow basally, with the anterior rays of both having dark grey-brown median and white distal bands. The caudal fin is dusky yellow, while the pectoral and pelvic fins are white. Juveniles have between 5 ...
The rehydrated mushroom can also be stuffed and cooked. [53] Phallus indusiatus has been cultivated on a commercial scale in China since 1979. [49] In the Fujian Province of China—known for a thriving mushroom industry that cultivates 45 species of edible fungi—P. indusiatus is produced in the counties of Fuan, Jianou, and Ningde. [54]
The pelvic floor muscles are located between the tailbone and the pubic bone within the pelvis. In females, they support the uterus and vagina, as well as the bowel and bladder.
The stipe is white in colour, smooth, [17] 3–7 cm (1–3 in) long by 2–3 cm (1–1 in) thick and is cylindrical, sometimes tapering towards the base. [11] There is a thick layer of firm white flesh, and the decurrent gills are particularly crowded and narrow, sharing the white colouration of the stem but becoming creamy with age.
