The Mexican blindcat (Prietella phreatophila), in Spanish bagre de muzquiz, is a species of North American freshwater catfish (family Ictaluridae). [1] [3] Until recently, it was believed to be endemic to Coahuila in the Rio Bravo drainage in northern Mexico; [1] [3] [4] however, in 2016 the species was reported from the Amistad National Recreation Area, Texas, following earlier, unconfirmed sightings of blind, white catfish in the area. The captured specimens were brought to the San Antonio Zoo and Aquarium. [5]

Habitat and conservation

The species lives only in subterranean waters and can be encountered in caves and wells. [5] [3] In Mexico, it is known from 12 locations. [6] [4] It is threatened by pollution of the groundwater [3] and groundwater extraction. [5]

Description

This fish is pinkish white in color and has no eyes. It grows up to 9.2 cm (3.6 in) in total length. The dorsal fin has no spine. The adipose fin is joined to the caudal fin, which is unforked. [6]

<span class="mw-page-title-main">Catfish</span> Order of fish

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.

The flathead catfish, also called by several common names including mudcat or shovelhead cat, is a large species of North American freshwater catfish in the family Ictaluridae. It is the only species of the genus Pylodictis. Ranging from the lower Great Lakes region to northern Mexico, it has been widely introduced and is an invasive species in some areas. The closest living relative of the flathead catfish is the much smaller widemouth blindcat, Satan eurystomus, a cavefish.

<span class="mw-page-title-main">Basa (fish)</span> Species of catfish

Basa, as it is commonly referred to, is a species of primarily freshwater-dwelling catfish in the shark-catfish family, Pangasiidae, native to the Mekong and Chao Phraya river basins of Mainland Southeast Asia. Economically, these fish are important as a regional food source, and are also prized on the international market. Outside of Asia, such as in North America or Australia, they are often referred to as "basa fish" or "swai" or by their specific name, "bocourti". In the United Kingdom, all species of Pangasius may, legally, be described as "river cobbler", "cobbler", "basa", "pangasius" or simply "panga", as well as any of these names with the addition of "catfish". In the rest of mainland Europe, these fish are mostly sold as "pangasius" or "panga". In Asian fish markets, names for basa also include "Pacific dory" and "patin". Other, related shark-catfish species may occasionally be labeled—albeit incorrectly—as basa, including the iridescent shark and the yellowtail catfish.
