NEMATOGNATHI Meaning and
Definition
-
Nematognathi is a term used in the field of zoology to refer to a group of primarily freshwater fishes that belong to the taxonomic order Siluriformes. Siluriformes, more commonly known as catfish, is a diverse order that comprises over 3,000 different species. Nematognathi is a specific suborder within Siluriformes that includes families such as Gymnotidae (electric knifefishes), Doradidae (thorny catfishes), and many others.
The distinguishing characteristic of the Nematognathi is the presence of an adipose fin, which is a small, fleshy fin located on the back of the fish, between the dorsal fin and caudal fin. This fin is thought to serve a variety of functions, such as enhancing maneuverability and stability during swimming.
Nematognathi fishes are known for their elongated and cylindrical bodies, often with barbels near the mouth. They typically have smooth, scaleless skin, and many species exhibit unique adaptations to their environments. For example, electric knifefishes in the family Gymnotidae are capable of generating weak electric fields that they use for navigation, communication, and prey detection.
These fish are found in a wide range of habitats, including rivers, streams, lakes, and swamps, primarily in tropical and subtropical regions. They exhibit a diverse array of feeding strategies and occupy various niches in aquatic ecosystems. Nematognathi fishes play important ecological roles, serving as both predators and prey, and are of economic and ecological significance to local communities.

Etymology of NEMATOGNATHI
The word "Nematognathi" is derived from Greek roots. In Greek, "nemato-" means "thread" or "thread-like", and "gnathi" means "jaw".
The term is used in the field of biology to refer to a group of fishes characterized by their long, thread-like jaws. These fishes belong to the order Siluriformes, commonly known as catfishes. The name "Nematognathi" thus describes the morphological feature of their jaws.
