The Notopteridae or Featherback Family includes four genera; Chitala, Notopterus, Papyrocranus, and Xenomystus and six species distributed throughout Southeast Asia and Africa.
Notopteridae - The Old World Featherback or Featherfin Knifefishes are fund in Southeast Asia to Africa.
They are characterised by having a long anal fin that joins with their small caudal fin and a small or absent dorsal.

The osteoglossiform family Notopteridae, whose members are also known as featherbacks or featherfin knifefishes, comprises eight species in four genera from tropical
Africa and Southeast Asia (Roberts 1992b; Kottelat et al.
These "Old World knifefishes" have a highly specialized body form and fins that include
an elongate anal fin joined to the caudal fin, a reduced dorsal fin, and ventral scutes (Roberts 1992b).

also called Knifefish, or Featherback, any of about eight species of air-breathing, freshwater fishes constituting the family Notopteridae, found in quiet waters from Africa to Southeast Asia.
Notopterids are long-bodied, small-scaled fishes with a small dorsal fin (if present) and a long, narrow anal fin that runs along most of the undersurface and continues into the tail fin.

I have been studing alien fish species in our waters for some time, one such species is
Clown Kinfe Fish/ Indian Knife Fish (Chitala chitala- Family Notopteridae).
This fish has become a serious invader specially in the coastal wetlands of Sri Lanka and this has affected the fishery in these wetlands and severly affected the livelyhood of local fishing communities.
The swim bladder has various functions in different fishes, acting as a float which gives the fish buoyancy, as a lung, as a hearing aid, and as a sound-producing organ.
In many fishes it serves two or three of these functions, and in the African and Asiatic knife fishes (Notopteridae) it may serve all four.
The swim bladder contains the same gases that make up air, but often in different proportions.
