Special Issue Information
Dear Colleagues,
Prominent poisonous and venomous animal classes that inhabit numerous ecological niches today, like invertebrates (e.g., marine cnidarians and terrestrial arthropods) and vertebrates (marine fishes and terrestrial reptiles), originated over a million years ago (mya) and continuously evolved after that. During biological and molecular evolution, genes coding for toxins and their expression products were selected to achieve high specificity and potency for their cellular targets. Each species' chemical and biological arsenal brings advantages in ecological warfare for defense, predation, and dispute for territory. Indeed, biological diversity can be understood and translated into combinatorial chemical and pharmacological possibilities. Modern venomics has advanced so well in technological aspects that the tiniest and hidden organisms can be assessed for their toxin contents and repertoires. The combination of "omics" sciences (genomics, transcriptomics, proteomics, etc.), computational biology, and essential pharmacological assays, such as in vitro 2-D, 3-D, and organoid cell systems, electrophysiology (e.g., voltage and patch-clamp recording), and in vivo insect (e.g., cricket), mouse, and zebrafish models, allow for and make possible the discovery of toxin structures, scaffolds, activities, and functionalities that have contributed to translating the basic research on toxins into different fields of applied sciences—from pest control (e.g., ion-channel blocker bioinsecticides) to diagnosing and treating chronic and degenerative diseases (peptide probes and antidiabetic, immunomodulator, and painkiller drugs). The present Special Issue aims to collect and make available to readers articles on the disclosure and description of toxin composition and frameworks in marine and terrestrial organisms using modern venomics analysis. In addition, venomics studies that bring new insights on peptide toxin evolution will be available to the scientific and interested community.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
