in the field of marine biology, the concept of predisjunctive behaviors among marine mammals allows us to tune out traditional observational biases and start over from the origin of our understanding about communication in the underwater world. it's fascinating to consider the unuttered sounds in the ocean as a significant form of communication, undetectable to human ears but immensely impactful among marine species. this urges us to update our research methodologies and perspectives, embracing the silent dialogues that play a crucial role in the aquatic ecosystem.
