Barracuda

Barracuda refers to several species in the family Sphyraenidae, with the great barracuda (Sphyraena barracuda) being the most widely known. Barracudas are large, predatory ray-finned fishes found in tropical and subtropical oceans worldwide, typically occupying coastal habitats such as reefs, mangroves, and seagrass beds.

Barracudas have elongated, fusiform bodies with a pointed head and a long, sharp-toothed jaw. Their skin is generally silvery with dark markings that can form bars or spots along the body. They are fast swimmers and rely on bursts of speed to ambush prey. Their diet mainly consists of smaller fish and squid, and they can hunt both alone and in small groups, depending on the species and life stage.

Distribution and habitat vary by species, but barracudas are commonly found in warm, coastal waters worldwide. They tend to favor structurally complex environments that provide cover and abundant prey. Adults are often solitary or form loose associations, while juveniles may be seen schooling.

Reproduction involves external fertilization, with eggs released into open water and developing into free-swimming larvae. Barracudas are of commercial and recreational importance in many regions, though their meat can carry risks in some tropical areas because of ciguatera toxin, so consumption is avoided in high-risk locations. They are also known for their potential to bite divers or fishermen, so caution is advised when handling them.
