Platichthys
''Platichthys'' is a genus of flatfish native to the North Pacific and North Atlantic oceans. Despite being in the family Pleuronectidae Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the o ... (popularly known as righteye flounders), all four species in the genus ''Platichthys'' are often "lefteyed", i.e. they lie on the sea bottom on their right side, with both eyes on the left side.

Platichthys Flesus
The European flounder (''Platichthys flesus'') is a flatfish of European coastal waters from the White Sea in the north to the Mediterranean and the Black Sea in the south. It has been introduced into the United States and Canada accidentally through transport in ballast water. It is caught and used for human consumption. The European flounder is oval in shape and is usually right-eyed. It normally grows about 30 cm in length, although lengths of up to 60 cm have been recorded. The upper surface is usually dull brown or olive in colour with reddish spots and brown blotches and this fish can change colour to suit its background, providing an effective camouflage. The underside is pearly-white, giving the fish one of its common names, the white fluke. The lateral line features rows of small tubercles, as do the bases of the dorsal and anal fins. Description The European flounder is a flatfish with an oval-shaped body with a width about half its length. The maximum recor ...

Kareius Bicoloratus
The stone flounder (''Platichthys bicoloratus'') is a species of flatfish in the family Pleuronectidae. It is a demersal fish that lives on sandy and muddy bottoms in coastal areas at depths of up to . Its native habitat is the temperate waters of the north-western Pacific, from Japan to the Kuril Islands, Sakhalin, Korea, northern China and Taiwan. It is oceanodromous and is found in salt, brackish and fresh waters. It can grow up to in length, and may reach 12 years of age. It was formerly classified in the now defunct genus ''Kareius''. Diet The stone flounder's diet consists of zoobenthos organisms such as amphipods, bivalves, mysids and polychaete Polychaeta () is a paraphyletic class of generally marine Annelid, annelid worms, common name, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called c ...s. References Platichthys stone flounder Marine fauna of East Asia ...

Flatfish
A flatfish is a member of the Ray-finned fish, ray-finned demersal fish Order (biology), suborder Pleuronectoidei, also called the Heterosomata. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. The most primitive members of the group, the Threadfin, threadfins, do not resemble the flatfish but are their closest relatives. Many important food fish are in this order, including the flounders, sole (fish), soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Due to their highly distinctive morphology, flatfishes were previously treated as belonging to their own order, Pleuronectiformes. However, more recent taxonomic studies have found them to group within a diverse group of nektonic marine fishes known as the Carangiformes, which also inc ...

Platichthys Solemdali
The Baltic flounder (''Platichthys solemdali'') is a species of flatfish endemic to the Baltic Sea, where it is the only known endemic fish species. It is sympatric with the closely related European flounder (''P. flesus''), which it looks identical to and can only be distinguished from via genetic analysis. However, both have very different spawning behaviors and habitat requirements; the strongly migratory European flounder requires a minimum level of salinity and spawns in the pelagic zone where its eggs are carried by the waves, whereas the largely resident Baltic flounder is more tolerant of salinity decreases and spawns in shallow neritic areas where its eggs sink to the seabed. Due to these different spawning behaviors, both species display a major degree of reproductive isolation, preventing them from intermixing and establishing them as different species. Analyses indicate that the Baltic flounder and the Baltic population of the widespread European flounder both derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleuronectidae
Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the opposite, with their eyes on the left side. A small number of species in Pleuronectidae can also have their eyes on the left side, notably the members of the genus '' Platichthys''. Their dorsal and anal fins are long and continuous, with the dorsal fin extending forward onto the head. Females lay eggs that float in mid-water until the larvae develop, and they sink to the bottom. They are found on the bottoms of oceans around the world, with some species, such as the Atlantic halibut, ''Hippoglossus hippoglossus'', being found down to . The smaller species eat sea-floor invertebrates such as polychaetes and crustaceans, but the larger righteye flounders, such as ''H. hippoglossus'', which grows up to in length, feed on other fishes and ...

John Otterbein Snyder
John Otterbein Snyder (August 14, 1867 – August 19, 1943) was an American ichthyologist and professor of zoology at Stanford University. History As a student he met David Starr Jordan who inspired him to enter zoology. He eventually became a zoology instructor at Stanford University and served there from 1899 until 1943. He went on several major collecting expeditions aboard the in the early 1900s and organized the U.S. National Museum's fish collection in 1925. The same year he also declined the directorship there so he could return to Stanford. He was a long-term member of the California Academy of Sciences and worked for the California Bureau of Fisheries. He wrote many articles and papers as well as describing several new species of sharks. San Francisco Bay In 1905, Snyder, then assistant professor of zoology at Stanford, published ''Notes on the fishes of the streams flowing into San Francisco Bay'' in ''Report of the Commissioner of Fisheries to the Secretary of Commerc ...
