1689 symbionts from 1114 crinoids of the Central Great Barrier Reef were assigned to 46 taxa from 5 invertebrate classes. Crinoid specimens were collected from 46 sites (24 sites on 12 reefs, 2 sites per reef, and 22 sites at Davies Reef, see separate metadata record).Species abundance and species richness were recorded and Cramer values applied. In addition, 46 taxa were identified as symbiotic associates of the crinoids.
