biont

Several of the fresh shells in our experiments had visual indicators of biont attack prior to the experiment, with visible black blisters on interior shell surfaces from polychaetes and bore holes from sponges (although no organisms were found in or on shells).

Molecular phylogenetics of bacterial endosymo bionts and their vestimentiferan hosts.

(1990): degree of dissolution, fragmentation, condition of fragmented edges, discoloration, abrasion, biont encrustation, and articulation (in M.

Each of these categories was further broken down into alternation of bionts (Biontenwechsel) and alternation of shoots (Sprosswechsel).
