What is the term for animal communication through water or air vibrations?

The term for animal communication through water or air vibrations is "acoustic." Animals utilize sound waves to convey information, interact with each other, and potentially navigate their environment. This form of communication can take many shapes, including calls, songs, or other vocalizations, and is especially prevalent among marine animals, such as whales and dolphins, who rely on sound to communicate over vast distances in water.

While chemical communication refers to the use of scent or pheromones to relay information, visual communication depends on sight and body language, and electromagnetic communication involves signals in the electromagnetic spectrum (like light), they do not encompass the transmission of information through vibrations in water or air. Therefore, acoustic is the correct choice as it specifically pertains to sound-based communication methods.
