The subfamily Corydoradinae is found east of the Andes and north of the Rio de La Plata system. [5] Representatives of the Corydoradinae are found in several freshwater environments, ranging from fast-flowing piedmont streams with sandy or rocky bottoms to lowland pools with muddy bottoms. [5] A single species, Aspidoras mephisto, is a cavefish ...
The vundu is the largest true freshwater fish in southern Africa, reaching up to 1.5 m (5 ft) in length and 55 kg (121 lb) in weight. [2] ( Bull sharks are also found in southern Africa and reach a larger size, but occur in both fresh and saltwater.)
It is the most species-rich genus of catfish in North America, [1] native to the central and eastern United States, and adjacent parts of Canada. [2] Their fin spines contain a mild venom with a sting comparable to that of a honey bee. [1] Nearly half the species of madtom catfishes were described in a single comprehensive revision of the group.
The golden cave catfish lack pigmentation and are up to 16.1 cm (6.3 in) in standard length. [2] They have very small eyes that are covered with skin, and are probably effectively blind. [2] They feed on detritus and invertebrates that fall into the lake in which they live. The population is estimated at 200–400 individuals. [6]

Standard lengths for mature fish may range up to 8 cm (3.1 in), but usually only reach around 6.5 cm (2.6 in) in total length. [1] Their bodies are transparent because, like all catfish, they lack scales.

[5] It also feeds on small fishes, frogs and shrimps. [10] B. suchus, however, is a piscivore. [5] B. yarelli feeds primarily on prawns but also eat small fishes and aquatic ...
Young Mekong catfish do exhibit barbels and oral teeth, but these features diminish as they age and are absent by the time they grow to be 30–50cm in length. [3] Mekong giant catfish are one of the largest species of freshwater fish. In 2005, the Mekong giant catfish attained the Guinness World Record for the world's largest freshwater fish.
