Barracudas are the common names for the members of the Sphyraenidae family. They are found in the tropical and subtropical parts of the Atlantic, Indian and Pacific oceans. Most of them inhabit shallow coastal waters such as bays, estuaries, or the vicinity of coral reefs, and also in the surface of open oceans or down to depths of 100 m or more. They are known for their large size (up to about 2 m long), fearsome appearance and fang-like sharp teeth. The barracudas are recognized by their elongated body, long and pointed head, two widely separated short dorsal fins and, large, sharp, flattened or conical teeth of unequal size on jaws and palatines.
Barracudas are carnivorous fish feeding commonly on other fishes. They may even attack human when provoked . They frequently occur in small to large schools, but some large adult are solitary. Some species are primarily diurnal, while others are nocturnal and occur in inactive schools during the day. They are frequently caught using artificial lures and live bait as the are attracted by flashing objects and wounded fish, particularly in murky water. Steel leader is used to prevent broken lines.
There is only one genus and 29 species of Sphyraenidae worldwide. Malaysia has about 7 species.
