Sponge cover (0-100%). Sum of benthic composition categories equals 100. No longer collected as of 2016 surveys; pooled into OTHER.

Other benthic composition value (0-100%). Sum of benthic composition categories equals 100. Turf algae, tunicates, zoanthids, corallimorphs, clams, cyanobacteria, soft coral, and sponges are pooled into this category as of 2016 surveys.

Other benthic composition type. No longer collected as of 2016 surveys.

4-letter code for TAXONNAME. Required.

Scientific name of observed organism to the finest taxonomic resolution that divers can identify a fish to, usually to species (see RANK). Required.

Common name (from FishBase).

Common name of all families.

Taxonomic classification: Family of observed organism (TAXONNAME).

Taxonomic classification: the true scientific name (genus and species) of the observed organism (TAXONNAME). If NULL, organism not identified to species taxonomic level (see RANK).

Lowest defined rank in taxonomic hierarchy.

Trophic level: APEX (apex predator), Cor (corallivore), H (herbivore), MI (mobile invertivore), Om (Omnivore), Par (parasite), Pisc (piscivore), Pk (planktivore), SI (sessile invertivore), X (if unidentified fish), Z (zooplantivore).
