anabantoidei

The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish.

The labyrinth organ of Anabantoidei and Clariidae is used to allow the fish to extract oxygen from the air.

The labyrinth organ, a defining characteristic of fish in the suborder Anabantoidei, is a much-folded supra branchial accessory breathing organ.

The Anabantoidei is a suborder of perciform ray-finned freshwater fish distinguished by their possession of a lung-like labyrinth organ, which enables them to breathe air.

The Anabantoidei have developed a special organ that allows them to take advantage of the oxygen of the air, but is not a true lung.The rare breath fish also has two lungs.
