The genus Anabas is a group of freshwater fish commonly known as climbing perch. There are several synonyms for this genus, including Ctenopoma, Colisa, and Anabasoides. The name Anabas comes from the Greek word "anabasis," meaning "climbing up," which describes the fish's unique ability to climb on land using their specialized gill chambers. These fish are found mainly in Southeast Asia, India, and Africa and are often used as a food source. Despite their appearance and behavior, they are not related to true perch. Understanding the various synonyms for this genus is important for those interested in the study of fish and their taxonomy.
