Researchers at the New York Aquarium observed two beluga whales displaying behaviors that may indicate self-recognition during a mirror test reported in May 2026 [1, 2].
This finding is significant because self-awareness is a complex cognitive trait. Identifying it in cetaceans helps scientists understand the evolution of intelligence and the mental capabilities of marine mammals.
The study focused on two specific whales, Natasha and her daughter Maris [2]. The researchers used a two-way mirror to monitor how the animals reacted to their own reflections. The whales exhibited behaviors in front of the glass that suggest they recognized the image as themselves rather than another animal, reports said [1, 2].
Such experiments utilize the mirror test, a standard psychological tool used to determine if an animal possesses a concept of self. While many species fail the test by reacting with aggression or curiosity toward the reflection as if it were a stranger, the behaviors of Natasha and Maris suggest a different level of processing.
The observations took place in New York City, where the aquarium's team sought to expand the list of species capable of self-recognition [1, 2]. This study adds to a growing body of evidence regarding the sophisticated social, and cognitive lives of whales.
While the results are promising, the mirror test remains a subject of debate among biologists. Some argue that visual recognition is not the only way to measure consciousness, especially for species that rely heavily on sound and echolocation to perceive their environment [2].
“Beluga whales displayed behaviors that may indicate self-recognition.”
The potential for beluga whales to pass the mirror test suggests that high-level cognition is not exclusive to primates and certain land mammals. If confirmed, this indicates that the biological requirements for self-awareness can evolve independently in aquatic environments, potentially shifting how conservationists and ethicists view the mental autonomy of cetaceans.
