The lesser weever (Echiichthys vipera) is a venomous weever of the family Trachinidae, in the order Perciformes, and the class Actinopterygii. It is generally found on the sandy sea beds of the open sea, near the shore. Lesser weevers may sting swimmers badly if disturbed in the water, and fishermen when they clean their fishing nets.
The lesser weever grows up to 18 cm long, but generally less than 15 cm, with an elongated body. Its color can be described as greyish-brown on the back and silvery-white on the sides. It has no spines in front of its eyes.
Lesser weever fish occur in the eastern Atlantic from the North Sea around the British Isles to Morocco and Madeira, and in the Mediterranean. They are typically found resting on the bottom, partially buried with eyes and tip of first dorsal fin exposed.
The lesser weever is littoral and benthic, living on sandy, muddy bottoms, ranging from a few meters deep to 150 m (in winter). Resting on the bottom, its position can be described as with eyes buried and the tip of the first dorsal fin exposed. Because of its venom and its occurrence near beaches, it is considered to be one of Europe's most dangerous weever species. The venom glands are located on its first dorsal fin, which is completely black, and on the gill cover. This species has the most potent toxin of all the weevers.
The sting of a weever is acute and intense. The pain frequently is radiated to the area around the limb. The seriousness of the pain reaches its peak 30 minutes after the sting, and then slowly decreases. However, some pain (or other sensation, such as a tingle) may continue to affect the area for up to 24 hours. Very rarely, pain can be propagated to the tributary lymph nodes, i.e. those in the groin (when the sting is on the sole of the foot), or those in the armpit (if the sting is on the hands).
