This document summarizes marine trait data available within the Encyclopedia of Life (EOL). It details that EOL contains over 500,000 trait records for around 290,000 marine taxa, inferred from 178 taxonomic nodes. Example datasets described include tissue mineralization records for 70,106 marine species, as well as data on distribution, habitat, and ecological associations. The structure of the trait data within EOL is also outlined.
