Genus Aspis is a taxonomic classification for a group of venomous vipers within the family Viperidae. Some synonyms for this genus include Vipera aspis, Aspis vulgaris, and Aspis atramentaria. These species are typically found in Europe and Western Asia, and are known for their distinctive triangular heads and long, sharp fangs. Although commonly referred to as "asp vipers," these snakes are not actually related to the asp species. Aspis vipers are often found in rocky habitats and can blend in with their surroundings through their cryptic coloration. Despite their venomous nature, Aspis vipers play an important role in ecosystems and are not typically aggressive towards humans unless provoked.
