. Fish of this family are commonly seen gulping at air at the surface of the water. The air is held in a structure called the suprabranchial chamber, where oxygen diffuses into the bloodstream via the respiratory epithelium covering the labyrinth organ. This therefore allows the fish to move small distances across land.
Genera
There are four extant genera within the family Anabantidae:

''Ctenopoma'' is a genus of climbing gouramies native to Africa. ''Microctenopoma'' has been included in ''Ctenopoma'' in the past; in contrast to that genus, ''Ctenopoma'' species are egg scatterers with no parental care.

Climbing gouramis are so named due to their ability to "climb" out of water and "walk" short distances. Even though it has not been reliably observed, some authors have mentioned about them having a tree climbing ability. Their method of terrestrial locomotion uses the gill plates as supports, and the fish pushes itself using its fins and tail.
