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.[1] Although they are generally harmless, Southern sennet have been linked to ciguatera poisoning.[2]

Description

Southern sennet, like other members of the Sphyraenidae family, possess elongated bodies, pike-like heads, and large jaws.[3] The lower jaw protrudes slightly from the upper jaw, both of which contain fang-like teeth.[3] They have two dorsal fins, which are widely separated on their backs. The anterior dorsal fin usually possesses spines while the posterior only has rays.[3] Southern sennet have 6 spines, and 9 rays on their dorsal fins. they have only 2 spines and 9 rays on their anal fins.[1] The longest recorded Southern sennet was 2 feet long;[4] the greatest recorded weight was 2 lbs 8 oz.[4]

Distribution and habitat

Southern sennet are known only from the western Atlantic ocean from Bermuda, Florida, and the Bahamas south to Uruguay.[1] They are found in tropical climates from 32°N to 38°S. Southern sennet live in costal waters near reefs, although they are more common over muddy bottoms,[5] at depths from 1-65 m,[6] where they often occur in in large schools near the surface.[6] Juveniles are commonly found over beds of seagrass.[6]
