June 20, 2010 : Barracuda
The barracuda is a ray-finned fish known for its large size and fearsome appearance. Its body is long, fairly compressed, and covered with small, smooth scales. Some species could reach up to 1.8m in length and 30 centimeters (11.8 in) in width. The barracuda is a salt water fish of the genus Sphyraena, the only genus in the family Sphyraenidae, and is found in tropical and subtropical oceans worldwide.
The collective name for a group of barracudas is a battery. They are voracious, opportunistic predators relying on surprise and short bursts of speed (up to 27 miles per hour (43 km/h)) to overtake their prey.
Adults of most species are more or less solitary, while young and half-grown fish frequently congregate. Barracuda prey primarily on fish, sometimes as large as themselves, by tearing off small chunks.
