Movie 1. From Fig. 4A. Mark-directed behavior by the dolphin at a mirror immediately after release from being marked on the head. A narrow plexiglass mirror, 41.9 cm ´ 101.6 cm ´ 0.32 cm is affixed in a vertical orientation to the exterior of one of the reflective walls (Wall 6). During this session, the mirror was the best reflective surface in the subject’s environment. The faint white line on the wall indicates the location of mirror.

Movie 3. From Fig. 4B. The dolphin at Wall 1, the best reflective surface in the session, exhibiting late sham-directed behavior: a continuous and repetitive sequence of 12 dorsal to lateral-ventral flips exposing the location of the sham-marked area of his body, the underside and tip of the right pectoral fin, to the reflective surface. This unusual behavioral sequence continued for 32 sec.
