Meaning of labyrinth organ | Babel Free

Definitions

An organ common to fish of the suborder Anabantoidei that enables them to breathe air.

Examples

“The labyrinth organ may work⟳ a bit like⟳ a lung, but it is an entirely different solution to the problem of how to remove⟳ oxygen from air.[…]The labyrinth organ is an effective adaptation to low-oxygen habitats.”

“The labyrinth organ fills most of the opercular cavity and is positioned behind and above the gill chamber and extends into the suprabranchial space; hence the name⟳ suprabranchial organ.”

“Anesthesia of fish⟳ with labyrinth organs (bettas, some gouramis, etc.) should be approached with caution. Owing to the unique anatomy of the labyrinth organ (enables fish⟳ to breathe⟳ atmospheric oxygen) and the gills of these fish⟳ (thick lamellae and ecreased lamellar surface area), it is possible to "drown⟳" the fish⟳ if an overdose of an anesthetic agent is given.”
