LABYRINTH FISH Meaning and
Definition
-
Labyrinth fish, also known as anabantoids, refer to a group of freshwater tropical fish belonging to the suborder Anabantoidei, which is a subdivision of the order Perciformes. This group of fish is characterized by a unique adaptation known as the labyrinth organ.
The labyrinth organ is a structure present in the gill cavity of labyrinth fish that enables them to breathe atmospheric air in addition to extracting oxygen from the water through their gills. This organ allows labyrinth fish to survive in oxygen-deprived stagnant waters, such as rice paddies, swamps, and slow-moving streams, which would be inhospitable to most other fish species.
Labyrinth fish are typically small to medium-sized, with diverse and vibrant coloration, making them popular choices for aquarium hobbyists. Some well-known examples of labyrinth fish include the Betta fish, Gouramis, and Paradise fish. These fish are native to various regions of Southeast Asia, particularly India, Thailand, and Indonesia.
Additionally, labyrinth fish are known for their unique breeding behavior. Males build bubble nests at the water's surface using plant materials and saliva. After courtship, the male entices the female to lay her eggs in the nest, after which he alone takes care of the eggs and later the hatchlings until they develop enough to swim independently.
Overall, the labyrinth organ adaptation and captivating behavioral traits make labyrinth fish a fascinating group of fish, both in their natural habitats and in the aquarium trade.
Etymology of LABYRINTH FISH
The etymology of the word "labyrinth fish" can be traced back to the Greek language. The word "labyrinth" comes from the Greek word "laburinthos", which originally referred to a building complex on the island of Crete in Greek mythology. This complex was said to contain a maze-like structure called the Labyrinth, constructed by Daedalus to house the Minotaur. Over time, the term "labyrinth" expanded to represent intricate and confusing arrangements or structures.
In the context of fish, "labyrinth" is used to describe a unique anatomical feature found in certain species. Labyrinth fish possess a specialized labyrinth organ, which enables them to extract oxygen directly from the surrounding air instead of solely relying on their gills. This adaptation allows them to survive in environments with limited oxygen levels, such as stagnant waters or temporary pools.
