In a 2006 study published in the Proceedings of the National Academy of Sciences researchers from the University of North Carolina Wilmington studying bottlenose dolphins in Sarasota Bay, Florida, found that the dolphins had names for each other. A dolphin chooses its name as an infant.

According to a 2024 article of a study of elephant calls in Amboseli National Park, Kenya and Samburu National Reserve and Buffalo Springs National Reserves between 1986 and 2022 done with machine learning, elephants learn, recognize and use individualized name-like calls.
