SUBCLASS DIPNOI Meaning and
Definition
-
Subclass Dipnoi, also known as lungfish, is a group of ancient, air-breathing fishes that belong to the class Sarcopterygii. The name "Dipnoi" is derived from the Greek words "di" meaning two or double, and "pnoe" meaning breath, referring to their ability to respire both underwater and in air.
These fascinating fishes are characterized by several unique features. They possess a modified swim bladder, known as a lung, which enables them to gulp air from the surface and extract oxygen, allowing them to survive in oxygen-poor environments. This adaptation is similar to the lungs found in land-dwelling vertebrates. Their bodies are elongated and covered in thick, bony scales, providing protection from predators. They also possess lobed fins that resemble limbs, suggesting a close evolutionary relationship to early tetrapods.
Subclass Dipnoi can be found in freshwater habitats of Africa, South America, and Australia. They are primarily nocturnal predators, feeding on a variety of invertebrates, small fishes, and even plants. They have the ability to aestivate, entering a dormant state during times of drought or extreme heat, by burrowing into the mud and secreting a mucus cocoon for protection.
Despite being considered ancient and primitive, Dipnoi have persisted for millions of years, and their unique characteristics provide crucial insights into the evolution of land-dwelling vertebrates.

Etymology of SUBCLASS DIPNOI
The word "Dipnoi" is derived from the Greek word "dipnoos" which means "double breathing". This term was coined by the Greek philosopher Aristotle in reference to the respiratory system of an ancient sub-class of fish, which includes lungfish.
The prefix "sub-" in "subclass" indicates a taxonomic rank below "class" and is used to categorize groups within a larger taxonomic classification system. So "Subclass Dipnoi" refers to a specific subcategory of the class of fish, comprising the lungfishes.
