9.1.1.1 part

With the exception of the groups Appendicularia_tail (Section 7.1.2.2), Chaetognatha_head (Section 7.2.2) and Chaetognaha_tail (Section 7.2.3), vignettes containing parts of individuals are classified in these groups Copepoda_part, Actinopterygii_scale and part_other.

9.1.1.2 multiple

By convention, each vignette represents a single individual. If more than one individual is on a vignette, the vignette is excluded from the multiple_other (Figure 9.2) or Copepoda_multiple (Figure 9.3) groups.
