The great barracuda (Sphyraena barracuda) also known as the giant barracuda, is a species of barracuda. Great barracudas often grow over 6 feet (1.8 m) long and are a type of ray-finned fish. Great barracudas are large fish. Mature specimens are usually around 60–100 cm (24–39 in) in length and weigh 2.5–9.0 kg (5.5–20 lb). Exceptionally large specimens can exceed 1.5 m (4.9 ft) and weigh over 23 kg (51 lb). The record-sized specimen caught on rod-and-reel weighed 46.72 kg (103.0 lb) and measured 1.7 m (5.6 ft). Barracudas are elongated fish with powerful jaws. The lower jaw of the large mouth juts out beyond the upper. Barracudas possess strong, fang-like teeth that are unequal in size and set in sockets in the jaws and on the roof of the mouth. The head is quite large and is pointed and pike-like in appearance. The gill covers do not have spines and are covered with small scales. In general, the barracuda's coloration is dark green or a blue type coloration or grey above chalky-white below. Sometimes, a row of darker cross-bars or black spots occurs on each side. The fins may be yellowish or dark. Barracudas appear in open seas. Barracudas are more or less solitary in their habits.
