Flounders are a group of flatfish species. They are demersal fish, found at the bottom of oceans around the world; some species will also enter estuaries.
The California halibut or California flounder is a large-tooth flounder native to the waters of the Pacific Coast of North America from the Quillayute River in Washington to Magdalena Bay in Baja California. It feeds near shore and is free swimming. It typically weighs 6 to 30 pounds. It is much smaller than the larger and more northern-ranging Pacific halibut that can reach 300 pounds (140 kg).
The New Zealand sand flounder is a righteye flounder of the genus Rhombosolea, found around New Zealand in shallow waters down to depths of 100 m.
The scoophead is a little-known species of hammerhead shark, part of the family Sphyrnidae. It inhabits the tropical waters of the western Atlantic Ocean, from Panama to southern Brazil, and in the eastern Pacific Ocean from the Gulf of California to Ecuador, and probably northern Peru, as well. It is found in shallow, inshore habitats.
The olive flounder, bastard halibut or Japanese halibut is a temperate marine species of large-tooth flounder native to the North-western Pacific Ocean.
The red-billed spurfowl, also known as the red-billed francolin, is a species of bird in the family Phasianidae. It is found in Southern Africa, including Angola, Botswana, Namibia, South Africa, Zambia, and Zimbabwe.
The African bullfrog is a species of frog in the family Pyxicephalidae. It is also known as the pixie frog due to its scientific name. It is found in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, and possibly the Democratic Republic of the Congo. It has long been confused with the edible bullfrog and species boundaries between them, including exact range limits, are not fully understood. Additionally, P. angusticeps of coastal East Africa only was revalidated as a separate species in 2013.
The European flounder 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 summer flounder is a marine flatfish that is found in the Atlantic Ocean off the East Coast of the United States and Canada. It is especially abundant in waters from North Carolina to Massachusetts.
Paralichthys lethostigma, the southern flounder, is a species of large-tooth flounders native to the eastern and gulf coasts of the United States. It is a popular sports fish and is the largest and most commercially valuable flounder in the western North Atlantic Ocean and Gulf of Mexico. It is a "left-eyed flounder", meaning the left side is pigmented and is the "up side".
Hippoglossina oblonga, is a flatfish and member of the large-tooth flounder family Paralichthyidae. This species has been placed in the genus Paralichthys by some authorities.
Citharichthys gordae, the mimic sanddab, is a species of sanddab in the large-tooth flounder family Paralichthyidae. It is native to the eastern Pacific Ocean, found off the coast of Mexico. It has a limited distribution, found in the Magdalena Bay and along the Baja California peninsula, as well as part of the Gulf of California.
Citharichthys platophrys, the small sanddab, is a species of sanddab in the large-tooth flounder family Paralichthyidae. It is native to the eastern Pacific Ocean, ranging from the southern Gulf of California of Mexico in the north to Peru in the south.
Citharichthys gymnorhinus, the anglefin whiff, is a species of flatfish in the large-tooth flounder family Paralichthyidae. It is a demersal marine fish that inhabits the mid to outer continental shelf of the western Atlantic Ocean, in both tropical and subtropical waters. It ranges from the Bahamas and Florida in the north to Guyana and Nicaragua in the south, though larvae samples have also been collected off the coast of Canada. It occurs at depths between 35 and 200 metres, but is most commonly found in shallower waters.
Citharichthys gilberti, the bigmouth sanddab, is a species of flatfish in the large-tooth flounder family Paralichthyidae. It is native to the eastern Pacific Ocean, in tropical waters ranging from the Gulf of California in the north to Peru in the south. It occurs in shallow waters off the coast, to a maximum depth of 36 m (118 ft).
The Gulf flounder is a species of saltwater flounder.
Hippoglossina is a genus of large-tooth flounders native to the coastal Pacific waters of the Americas. A single species, H. oblonga is found along the Atlantic coast of United States and Canada, but it is frequently placed in Paralichthys instead of Hippoglossina.
Paralichthys is a genus of large-tooth flounders. Most species are native to the coastal waters of the Americas, but P. olivaceus is from northeast Asia. The largest species reaches about 1.5 m (5 ft) in length.
Citharichthys cornutus, the horned whiff, is a species of flatfish in the large-tooth flounder family Paralichthyidae. This bathydemersal marine fish inhabits the continental shelves of the western Atlantic Ocean, in both tropical and subtropical waters. It ranges from New Jersey in the north to Uruguay in the south, though larvae samples have also been collected off the coast of Canada. It occurs at depths between 30 and 400 metres, though it is usually found in deeper waters.
Philasterides dicentrarchi is a marine protozoan ciliate that was first identified in 1995 after being isolated from infected European sea bass reared in France. The species was also identified as the causative agent of outbreaks of scuticociliatosis that occurred between summer 1999 and spring 2000 in turbot cultivated in the Atlantic Ocean. Infections caused by P. dicentrarchi have since been observed in turbot reared in both open flow and recirculating production systems. In addition, the ciliate has also been reported to cause infections in other flatfishes, such as the olive flounder in Korea and the fine flounder in Peru, as well as in seadragons, seahorses, and several species of sharks in other parts of the world.
