Trachiniformes is an order of percomorph bony fish, whose contents are traditionally placed in suborder Trachinoidei of Perciformes.

Weevers are nine extant species of fishes of family Trachinidae, order Trachiniformes, part of the Percomorpha clade. They are long, mainly brown in color, and have venomous spines on their first dorsal fin and gills. During the day, weevers bury themselves in sand, just showing their eyes, and snatch prey as it comes past, which consists of shrimp and small fish.
