In previous posts, we have mentioned a lot on fish using sound to communicate, hunt for prey, mate, and navigate. Have you wondered how exactly do fishes use sound to communicate and how does it sound like when a school of fish communicate under the ocean?
Humans can detect sounds that range from frequency 20 Hz to 20 kHz. As such, the frequency in which some dolphins and whales produce when they communicate is audible to humans. Whereas others are at a frequency too high or low that is inaudible to us. The video below explains how fishes communicate under the ocean and showcase how the advancement of technology has helped the researchers to explore the sounds under the ocean.

If you’re interested, this website by the National Oceanic and Atmospheric Administration provides a list of sounds produced by marine animals ranging from Humpback Whales to Leopard Seals! 😀
