“The Leviathan’s Playing” cycle is a multidisciplinary research project interacting with gray whales in the Ojo de Liebre lagoon in the Baja California peninsula (Mexico). The project started with a single premise: to read poetry to the whales. After an encouraging initial response to human lyrical stimulus from these cetaceans, the cycle’s efforts were directed toward developing a mediation system with this species and attempting to understand their behavior during close interactions with humans. This paper discusses the project’s findings from 2017 to 2021.
