What is the scientific name of the walking catfish, an air-breathing freshwater fish?

The scientific name of the walking catfish is Clarias batrachus.

This Southeast Asian catfish can move over short distances on land, especially when conditions are wet. It uses modified structures around its pectoral fins and body movements to help propel itself, although it does not literally walk like a land animal.

The species also breathes atmospheric oxygen through an accessory breathing organ. That ability allows it to survive in shallow, oxygen-poor water and helps explain its success in temporary habitats.

Walking catfish have been introduced to regions outside their native range, including parts of the United States, where they can compete with native species. The name is sometimes applied loosely to other air-breathing catfish, so the scientific name is important for precise identification.
