SIMPER analysis on biofacies and species life habit information.

Only species with a Sim/SD ratio >1 are included. Abbreviations: average contribution/standard deviation (Sim/Sd), % species contribution (Contrib. %), cumulation of % species contribution (Cum.%). Tiering: surficial (SU), semi-infaunal (SM-I), shallow-infaunal (SH-I), deep-infaunal (DP-I). Feeding: suspension (SF), detritus (DT), deposit (DP), chemosymbiotic (CH). Underlined taxa were used as reference names of the biofacies in the text. Nucinella sp. is the only shown species with Sim/SD ratio <1.
