Whales are the ocean’s social creatures who almost always travel in pods. They use a variety of sounds to socialize with one another. Mainly using clicks, whistles and pulses.   

These giants need sound to navigate through the ocean and stick together. The National Ocean Service put out an article that dives deep into what the sounds mean. The article stated that the clicking sounds are necessary for them to navigate as they migrate across the vast open sea. From the sound wave they create they bounce off of objects, then the waves return to the whale, allowing the whale to identify the shape of the object. These clicks can even help to differentiate between friendly creatures and predators. 

Some other sounds they make whistles and pulse which make it seem as if the whales are singing. These types of sounds are used for social activities. A pulse call to the human ear sounds like a squawk and a screeching noise. The pulses help the whales differentiate their pod from strangers. It has been studied that each pod has its own distinct whistles and pulses.
