Plicofollis is a genus of sea catfishes found along the coasts of the Indian Ocean from Africa to Australasia with some species ranging up into the Philippines. They occur in marine, brackish and fresh waters. There are currently eight described species in this genus.
The Indian Ocean is the third largest of the world's oceanic divisions, covering 70,560,000 km2 (27,240,000 sq mi). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica.
Africa is the world's second largest and second most-populous continent, being behind Asia in both categories. At about 30.3 million km2 including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, the Isthmus of Suez and the Red Sea to the northeast, the Indian Ocean to the southeast and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognised sovereign states (countries), nine territories and two de facto independent states with limited or no recognition. The majority of the continent and its countries are in the Northern Hemisphere, with a substantial portion and number of countries in the Southern Hemisphere.
Australasia comprises Australia, New Zealand, and some neighbouring islands. It is used in a number of different contexts including geopolitically, physiogeographically, and ecologically where the term covers several slightly different but related regions.
Achille Valenciennes was a French zoologist.
Albert William Christian Theodore Herre was an American ichthyologist and lichenologist.
Francis Day was an army surgeon and naturalist in the Madras Presidency who later became the Inspector-General of Fisheries in India and Burma. A pioneer ichthyologist, he described more than three hundred fishes in the two-volume work on The Fishes of India. He also wrote the fish volumes of the Fauna of British India series. He was also responsible for the introduction of trout into the Nilgiri hills, for which he received a medal from the French Societe d'Acclimatation. Many of his fish specimens are distributed across museums with only a small fraction deposited in the British Museum, an anomaly caused by a prolonged conflict with Albert Günther, the keeper of zoology there.
Epinephelus is a genus of fishes in the family Serranidae found in Atlantic, Indian, and Pacific Oceans.
Kryptopterus is a genus of catfishes belonging to the family Siluridae. They are found in freshwater throughout Southeast Asia. The scientific name comes from Ancient Greek kryptós + ptéryx. It refers to the reduced or even entirely absent dorsal fin of these catfishes.
Pseudoplatystoma tigrinum, the tiger sorubim, is a species of long-whiskered catfish native to the Amazon Basin in South America.
Oxydoras is a genus of thorny catfishes native to tropical South America.
Hemibagrus is a genus of catfishes of the family Bagridae.
Mystus is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.
Leiocassis is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China.
Nemacheilus is a genus of stone loaches native to Asia.
Aspredinichthys is a genus of banjo catfishes found in fresh and brackish waters in tropical South America from the Orinoco delta, through the Guianas, to the Amazon delta. Both species are found in lower portions of rivers and in coastal waters of northern South America from Venezuela to northern Brazil where they are benthic fish.
Amphiarius is a genus of sea catfishes of the family Ariidae. It includes two species, the Kukwari sea catfish, A. phrygiatus, and the softhead sea catfish, A. rugispinis.
Arius is a genus of catfishes of the family Ariidae. The genus Arius is distributed in brackish and fresh waters of Eastern Africa and south to Southeast Asia.
Aspistor is a genus of sea catfishes found along the northeastern coast of South America, where they occur in marine, brackish, and fresh waters.
Mystus nigriceps, the two-spot catfish, is a species of catfish of the family Bagridae. The species was available in aquarium circles without a scientific name until a connection was made to a description of Mystus micracanthus by the ichthyologist Bleeker, in 1846. The artist's impression at that time showed a catfish without any obvious markings, although another researcher in the early 1940s described it with two body spots. M. micracanthus is a junior synonym of M. nigriceps.
Ompok is a genus of fish in the family Siluridae found in lakes and large rivers throughout South and Southeast Asia.
Heterobranchus is a genus of airbreathing catfishes native to Africa. However, H. palaeindicus, the only known extinct species of the genus, was discovered in the Siwalik Hills, India, dating to the Lower Pliocene.
Trachelyopterus is a genus of driftwood catfishes
Cephalocassis is a genus of sea catfishes found along the coasts and in rivers and lakes of southern Asia from India to Malaysia. There are currently four described species in this genus.
Nemapteryx is a genus of sea catfishes found mostly in coastal marine and brackish waters from South Asia to Australia with one species occurring exclusively in fresh waters of the Fly River in Papua New Guinea. There are currently six recognized species in this genus.
Sciades is a genus of sea catfishes mostly found along the Atlantic Ocean and Caribbean Sea coasts of Central and South America. One species, S. dowii, occurs on the Pacific side from Panama to Ecuador, another, S. paucus, is a freshwater form found in Australia, while S. sona is a widespread species found along the Indian Ocean coasts of South Asia east into the Pacific to Polynesia. The genus Ariopsis has been merged with Sciades by some authorities.
FishBase is a global species database of fish species. It is the largest and most extensively accessed online database on adult finfish on the web. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.
