Structural similarities reveal an expansive conotoxin family with a two‐finger toxin fold

Protein Science, Volume 34, Issue 11, November 2025.
Abstract Venomous animals have evolved a diverse repertoire of toxins with considerable pharmaceutical potential. The rapid evolution of peptide toxins, such as the conotoxins produced by venomous marine cone snails, often complicates efforts to infer their evolutionary relationships based solely on sequence information.

Unveiling the Evolutionary History of European Vipers and Their Venoms From a Multi‐Omic Approach

Molecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Snake genomes attract significant attention from multiple disciplines, including medicine, drug bioprospection, and evolutionary biology. However, genomic research within the Viperidae family has mostly focused on the subfamily Crotalinae, while the true vipers (Viperinae) have largely been overlooked.

Are ticks venomous animals? [PDF]

, 2017
[Introduction]: As an ecological adaptation venoms have evolved independently in several species of Metazoa. As haematophagous arthropods ticks are mainly considered as ectoparasites due to directly feeding on the skin of animal hosts. Ticks are of major
