Catfish are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores, and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, but others are crepuscular or diurnal.
Lake Lyndon B. Johnson is a reservoir on the Colorado River in the Texas Hill Country about 45 miles northwest of Austin. The reservoir was formed in 1950 by the construction of Granite Shoals Dam by the Lower Colorado River Authority (LCRA). The Colorado River and the Llano River meet in the northern portion of the lake at Kingsland.
Teleostei, members of which are known as teleosts, is by far the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant species of fish. Teleosts are arranged into about 40 orders and 448 families. Over 26,000 species have been described. Teleosts range from giant oarfish measuring 7.6 m (25 ft) or more, and ocean sunfish weighing over 2 t, to the minute male anglerfish Photocorynus spiniceps, just 6.2 mm (0.24 in) long. Including not only torpedo-shaped fish built for speed, teleosts can be flattened vertically or horizontally, be elongated cylinders or take specialised shapes as in anglerfish and seahorses.
The kinkajou is a tropical rainforest mammal of the family Procyonidae related to olingos, coatis, raccoons, and the ringtail and cacomistle. It is the only member of the genus Potos and is also known as the "honey bear". Kinkajous are arboreal, a lifestyle they evolved independently; they are not closely related to any other tree-dwelling mammal group.
The Ocmulgee River is a western tributary of the Altamaha River, approximately 255 mi (410 km) long, in the U.S. state of Georgia. It is the westernmost major tributary of the Altamaha.
Corydoras is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae. The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where Corydoras is not present. Corydoras species are distributed in South America where they can be found from the east of the Andes to the Atlantic coast, from Trinidad to the Río de la Plata drainage in northern Argentina. Species assigned to Corydoras display a broad diversity of body shapes and coloration. Corydoras are small fish, ranging from 2.5 to 12 cm in SL., and are protected from predators by their body armor and by their sharp, typically venomous spines.
Jackson Lake is one of the oldest reservoirs in Georgia, United States, 44 miles (71 km) southeast of Atlanta in a rural area situated within parts of three counties. The Lloyd Shoals Dam was built in 1910 by Central Georgia Power Company, and electricity was originally generated for the city of Macon. Relative to others in the state, it is a smaller lake, which still generates electricity and provides a location for water sports, boating, wakeboarding and fishing.
Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Around 99% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with over 95% belonging to the teleost subgrouping.
Corydoras julii is a small freshwater catfish native to eastern Brazil. It is often confused with Corydoras trilineatus.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
Hyalobagrus is a genus of bagrid catfishes found in Southeast Asia.
Madtoms are freshwater catfishes of the genus Noturus of the family Ictaluridae. It is the most species-rich family of catfish in North America, native to the central and eastern United States, and adjacent parts of Canada. Their fin spines contain a mild venom with a sting comparable to that of a honey bee.
Galeichthys feliceps, the white barbel, sea barbel, white baggar or white sea catfish, is a species of sea catfish found in coastal waters and estuaries over muddy bottoms at depths of from 1 – 120 metres where they gather in large shoals. They occur from Namibia to South Africa with questionable records of sightings from Madagascar and Mozambique in Africa and the United States of America and Mexico in North America. It is coloured brown, grey or greenish-brown on the upperparts and is paler below. While most grow to a length of 35 cm, some individuals attain a length of 55 cm with a record of a fish from South Africa weighing 3.8 kg.
Hyalobagrus leiacanthus is a species of bagrid catfish endemic to Indonesia where it is known only from the Kapuas River and the Barito River basins in central Borneo.
Hyalobagrus ornatus is a species of bagrid catfish found in Indonesia, Malaysia and Thailand. It is found in the Muar River drainage in the southern Malay Peninsula of Malaysia and Thailand and Kapuas basin in western Borneo. It occurs in streams and peat swamps.
Rita macracanthus is a species of bagrid catfish found in the Indus River drainage. It has been recorded from Afghanistan, India and Pakistan. It grows to a length of 26.3 cm.
Silonia childreni is a species of schilbid catfish endemic to India where it occurs in the Krishna, Godavari and Cauvery River systems of the Western Ghats. This species grows to a length of 48 centimetres (19 in) TL. These fish occur in large rivers and reservoirs. A gregarious fish and move in shoals during monsoon. They feed on fish. S. childreni is a dominant species in the catches from deep waters, especially during the monsoon months between April and July.
Noturus flavus, the stonecat, is a North American freshwater catfish of the family Ictaluridae. The common name is due to its habit of hiding near or under stones in fast-moving water.
