Figure 7. Body patterns produced by Metasepia pfefferi.

The 11 patterns produced by freely behaving, sexually mature Metasepia pfefferi in their home aquarium as recognized by the AutoClass@IJM automated signal classification system. Each component included in a pattern depiction was observed in >50% of the 1-s clips sorted into that pattern category. As described in the text, each pattern is sorted into 4 color categories (as seen by the human eye): dark, yellow, white and pink. If no single color was observed in >50% of the 1-s clips for a certain body area (e.g., arms in Pattern 1 and head in Pattern 3) it is depicted as gray. Arrows on the illustrations indicate the direction and the start and end points for traveling components.
