Parapercis Maculata
''Parapercis maculata'', the harlequin sandperch, is a species of marine Actinopterygii, bony fish in the Family (biology), family Pinguipedidae, found in shallow waters in the tropical western Indo-Pacific Ocean. Description The harlequin sandperch grows to a maximum length of . It is cylindrical at the front but somewhat compressed at the back. The head is large with an oblique mouth and the eyes set near the top. There is a spine on the Operculum (fish), operculum. The dorsal fin has five spines and twenty-one (occasionally twenty-two) soft rays. The fourth spine is the longest. The anal fin has a single spine and eighteen or nineteen soft rays. The general colour is pale reddish or greyish brown, shading to white on the underparts. There are large irregular reddish-brown blotches on the back, with six distinctive reddish-brown, squarish blotches below the lateral line. The dorsal fin has rows of small orange spots on the soft rays, and the anal fin has rows of white spots. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...
