anyone looking for an overview of each test carried out and the results can do so here. https://www.researchgate.net/publication/342706263_Language_Research_Dolphins https://www.researchgate.net/publication/342706263_Language_... I didn't realize until fairly recently that we had strong evidence of language understanding of any other animal and for decades too. It's technically not evidence of natural language use but I find the idea that these highly social animals have the ability to understand an artificially constructed language but don't use one naturally highly suspect.
