Lesser Weever (Echiichthys vipera) is a venomous fish of the family Trachinidae. It lives on the sandy sea beds of the open sea, near the shore, in the eastern Atlantic and in the Mediterranean. Lesser weever may sting swimmers badly if disturbed in the water. It buries itself partially and lies in ambush to catch smaller fishes. It is generally less than 15 cm long. It is Europe's most dangerous weever species with the most potent toxin. In German it is called Viperqueise (aus der Familie der Petermaennchen). It filled my mind as I fall a victim to it myself this summer.
