labyrinth organ
By Shirlie Sharpe
Definition: Labyrinth organ is an accessory respiration organ in some fishes that allows them to breath air.


: An organ found on anabantids (labyrinth fish.) They are wrinkled areas located above the eyes, which enable them to take in oxygen from the water surface, or when on land.

The labyrinth organ is also used by those species that build bubblenests. Air is spit out and contains an oily surface so the bubbles adhere to each other. The fertilized eggs are then spit into the bubblenest which is guarded by the male.

The , a defining characteristic of fishes in the suborder Anabantoidei, is a much-folded suprabranchial accessory breathing organ.

*The labyrinth organ is a much-folded suprabranchial accessory breathing organ found in labyrinth fish, of the Anabantoidei family. Formed by vascularized expansion of the epibranchial of the first gill arch.

Due to their , which allows them to breathe air at the water's surface, bettas can live in less oxygen-rich water than can other fish.

Their name is derived from the Labyrinth Organ that all the fish in the sub-order possess. This organ enables this fish to breathe in oxygen-deprived waters.

Bettas and Gouramis are beautiful labyrinth fishes meaning that they get air at the surface of the water through a .

They have a labyrinth organ, which enables them to breathe air. I like using Colisa lalia, the dwarf gourami. Keep two females per male, to avoid too much bullying. They come in several colour morphs. I've seen a blue, red and green version.

Fish with s or primitive lungs, like bettas and gouramis, various polypterus and lungfish would be extremely unlikely to suffocate in a bag , and you can usually take your time acclimating them.

This is due to a special breathing organ referred to as the labyrinth organ which is essentially a maze of tunnels near the fish's gills.

Labyrinth fish are named for the found in the head that allows the fish to breath oxygen from the surface of the water. This means that they can temporarily survive in water with a low oxygen content.

Although the labyrinth organ allows the fish to survive in oxygen depleted water, it is a common misconception that this makes water changes unnecessary.

Anabantids rise to the surface and take gulps of air which pass to the where the oxygen is absorbed by the tissues. The labyrinths are located on the top of the head, behind the eyes.

They are capable of living in small homes because of their labyrinth organ which they use to breathe air from the surface; therefore, they don't NEED large quantities of water like other fish. But they love to have lots of space.

Because if this , it is not unusual to see it go to the surface and gulp air. The ability to breathe air allows them to survive in very low oxygen situations.

Labyrinth fish gulp air at the surface of the water and absorb it through the labyrinth organ, allowing them to live in water with too little oxygen to support fish which only breath through their gills.

They are labyrinth fish, having the ability to breathe air through their . Gouramis are typically found in Asia, India and South East Asia. Some popular gourami species include the brightly colored dwarf gourami and the pearl gourami.

Characterized by a specialized respiratory organ, the labyrinth organ, which enables the fish to obtain oxygen from the air, allowing it to live in water with low levels of dissolved oxygen. This family of fishes includes bettas and gouramis.

" An anabantoid is a fish which has adapted to its oxygen-poor environment by developing a . This organ is an auxiliary to the gills. It allows the fish to extract oxygen from the air as well as the water.

So can gouramis, which evolved in the low-oxygen conditions of shallow, stagnant ponds in Southeast Asia and have what is known as a labyrinth organ.

You need a tightly sealing lid for the top of the tank, as betta fry need the air and water temperatures to be the same in order to properly develop the (common to the family Anabantidae).

Danios swim near the top of the water and are famous for their survival ability (I believe they used them in nuclear experiments in the 50s). Gouramis and bettas can directly breath air, through their labyrinth organ.

The male will tend to the eggs until they hatch. After hatching, there should be frequent water changes, especially during the third week, as this is when the is developing. The fry should be fed infusoria and nauplii.

The high humidity is necessary for the development of the labyrinth organ. They are kept covered for 4-5 weeks, during which they will begin to move about the container. Some fry will begin to show color by the 5th week.
