Motivation: I present a database that contains information on multiple key traits for all 11,744 recognized species of squamates worldwide. The database encompasses key traits and hopefully a reasonably comprehensive picture of available public knowledge. I present a comprehensive description of the sources and rationale leading to the assignment of each particular trait state for each species. Hopefully, the dataset can serve the scientific community and promote research and understanding of the group, comparisons with other taxa, and assessment of conservation needs. Furthermore, gaps in our knowledge of squamate traits become readily apparent and will hopefully lead to further study and even better knowledge.

Main types of variables contained: morphological, ecological, life history, geographic and conservation-related traits

Spatial location: Global

Time period: Late Holocene to recent

Major taxa and level of measurement: Squamata, species

Software format: .xlsx

Data were manually collected over 18 years.
