* [[Bottlenose dolphin]] (''Tursiops truncatus''): Researchers in a study on two male bottlenose dolphins observed their reactions to mirrors after having a mark placed on them. Reactions such as decreased delay in approaching the mirror, repetitious head circling and close viewing of the eye or genital region that had been marked, were reported as evidence of MSR in these species.<ref>{{cite book |doi=10.1017/CBO9780511565526.026 |chapter=Evidence of self-awareness in the bottlenose dolphin (''Tursiops truncatus'') |title=Self-Awareness in Animals and Humans |year=1994 |last1=Marten |first1=Kenneth |last2=Psarakos |first2=Suchi |pages=361–379 |isbn=978-0-521-02591-1 }}</ref><ref name="Reiss">{{cite journal |last1=Reiss |first1=Diana |last2=Marino |first2=Lori |title=Mirror self-recognition in the bottlenose dolphin: A case of cognitive convergence |journal=Proceedings of the National Academy of Sciences |date=8 May 2001 |volume=98 |issue=10 |pages=5937–5942 |doi=10.1073/pnas.101086398 |pmid=11331768 |pmc=33317 |bibcode=2001PNAS...98.5937R |doi-access=free }}</ref>
