• Epibranchial organ

     Epibranchial organ - an additional respiratory organ, is a protrusion of the pharynx, the mucous membrane of the walls of which is permeated with a large number of blood capillaries, in which gas exchange occurs. Snakeheads, labyrinth fish, jumping fish and some other fish have the suprajaber organ.

     Epibranchial organ is located below the gill cavity and connects with it in front of the first gill arch. The supra-gill cavity is lined with mucous membrane, which is well supplied with a network of blood capillaries. Air is taken by the mouth and conducted into the supra-gill cavity, where oxygen is absorbed by a network of blood vessels and capillaries. This way of breathing is quite effective, and fish often use it.
