anabantoid

The anabantoids are called ”labyrinth fishes” because every species in the entire suborder possesses paired suprabranchial chambers that function for air breathing (Das, 1927; Bader, 1937; Peters, 1978)[…]Early discussions of the form and possible function of the anabantoid labyrinth organ are contained in Peters (1846, 1853), Zograff (1886, 1888), and Henninger (1907).
