Niphon spinosus is a marine fish from the order of the perch-like (Perciformes) that occurs in the western Pacific on the coasts of Japan, Korea, China and the Philippines in rocky reefs and over rocky bottom at depths of 100 to 200 meters.
features
Niphon spinosus is typical perch shape, has a moderately elongated, laterally flattened body, becomes about one meter long and reaches a maximum weight of 11 kg. The standard length is 2.9 to 4.2 times the body height and 2.5 to 2.8 times the head length. The profile of the large head is straight and the area between the eyes is slightly convex. The gill cover has three strong spines. Its upper edge is convex. The praeoperculare is angular, the posterior margin sawn, with a large backward-pointing thorn and a few smaller ones underneath. The front and rear nostrils are close together, the rear ones are narrow slits. The mouth is large with a protruding lower jaw. The jaw, ploughshare (vomer) and palatine bone (os palatinum) are dentate, the tongue is edentulous. The gill rakes are long and thin.
- Fins formula : dorsal XIII / 10–11, pectoral 15–17, anal III / 6–8, caudal 7/8.
- Scale formula : mLR 140–163, SL 84–93.
The dorsal fin has a deep gap in front of the last fin spine, which is much longer than the twelfth spine. The fourth spine is the longest and is also longer than all the soft rays of the second dorsal fin section. The pectoral and pelvic fins are roughly the same length. The scales are small and rough.
Niphon spinosus is brown-gray in color, the fins are darker. Young fish are silvery and show a dark band that extends from the tip of the snout through the eye to the upper section of the caudal peduncle and above that a second band that extends from the tip of the snout over the top of the head over the back to the front half of the second, soft-beamed dorsal fin. The upper and lower third of the caudal fin are dark, the middle section and the ends of the slightly indented caudal fin are white.
Systematics
Niphon spinosus in 1828 by the French naturalist Georges Cuvier described and is the only type of order monotypic genus Niphon . The fish has a long history of different systematic classification and has already been assigned to the codfish (Percichthyidae), the Centropomidae and, most recently, in a monotypical tribe Niphonini, the groupers (Epinephelinae). Betancur-R. and employees put the perch in the second version of their revision of the bony fish system from November 2013 into an independent, monotypical family, the Niphonidae, after WL Smith and colleagues had already established in 2007 that the Niphon spinosus is closer to the real perch (Percidae) than to spikes - and other sawfish (Serranidae) is related.
