Alvina Bristlers

== Overview ==
Alvina Bristlers (or Bristlefish) are a diverse group of whiskered fish. Named for their prominent barbels, which resemble a cat's whiskers, Alvina Bristlers range in size and behavior based on the region in which they live, and how much access to food and mating opportunities they have. The Matka Giant Bristler is the largest of the species at 2.7 meters in length, while the Northern Magellan Bristler is the smallest, at only 4.1 centimeters in length. All species contain highly advanced gills, allowing them to survive in highly anaerobic environments. Alvina Bristlers are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Magellan Bristler, are important in the aquarium hobby.
