Occurrence and trait data of medically important venomous snake species

This dataset provides a standardized compilation of occurrence and biological trait data for 373 medically important venomous snake species based on the <b>World Health Organization (WHO) Category 1 and 2 classification (WHO, 2024)</b>. The dataset integrates georeferenced distribution records, venom characteristics, and Red List conservation statuses to support global analyses of venomous snake diversity, medical importance, and biogeography.There are two files included:<b>1. snake_data.csv</b> — occurrence records for medically important snake species;<b>2. snake_info.csv</b> — species-level information including toxicity type and WHO medical importance categories.<br><b>File 1: snake_data.csv</b><b>Description:</b><br>Contains georeferenced occurrence records of venomous snake species from GBIF, iNaturalist, and The Atlas of Living Australia compiled between 1900 and 2025. <br><b>Variables:</b><b>Variable</b><b>Description</b>sourceData source (GBIF, iNaturalist, ALA)gbifIDUnique occurrence identifier from the source databasefamilyTaxonomic familygenusGenus namespeciesSpecies epithetdecimalLatitude, decimalLongitudeGeographic coordinates (WGS84)eventDateObservation or collection date (YYYY/MM/DD)redlistCategoryIUCN Red List status (e.g., Least Concern, Endangered)<br><b>File 2: snake_info.csv</b><b>Description:</b><br>Provides species-level trait and classification data for all 373 medically important venomous snakes.
