Greater weever

The greater weever (Trachinus draco, Linnaeus 1758) is a benthic and demersal venomous marine fish of the family Trachinidae. The greater weever is widely distributed along the eastern Atlantic coastline from Norway to Morocco, extending to the Mediterranean, Aegean and Black Seas. Trachinus draco has been shown to occur in depths ranging from shallow water up to -150 meters where it inhabits mostly muddy or sandy grounds. Trachinus draco is mostly and notoriously known for its venomous spines that can inflict serious injuries on humans through accidental stinging. Because of these spines and its potent venom it is classified as one of the most venomous fishes in the Mediterranean.⁠ The name “weever” is thought to originate from the Anglo-Saxon word “wivre” which translates as “viper”.
