The southern sennet, Sphyraena picudilla, is an ocean-going species of game fish in the barracuda family, or Sphyraenidae. It was described by the Cuban zoologist Felipe Poey. The description was part of a two-volume work, which Poey published in 1860, entitled Historia Natural de la Isla de Cuba or Natural History of the Island of Cuba. Southern sennet are sometimes used as a food fish, and marketed either fresh or frozen. Although they are generally harmless, Southern sennet have been linked to ciguatera poisoning.
