Loudest of Them All
Sperm whales are an extremely succesful whale species as they boast some of the best skills that a whale could possess. They are known for their extreme diving depths being able to submerge nearly 10,000 feet deep to areas in which even light can't pierce. The reasoning behind this ability is for them to be able to hunt their main form of sustenance: giant squid. Being one of the few whale species which actively hunt other large sea creatures makes them almost fantastical in the sense of their place in the food chain. It is rare for two seemingly apex predators to see each other as food as this can be paradoxical due to how energy moves through the chain itself.
Beyond their hunting skills, Sperm whales also possess the ability to execute extremely loud and long calls that can be heard miles away in water. This is an intense feat as water acts as a natural barrier for most noise, which can make people wonder what their call would sound like if it were above water. Their call may exist to be this loud for them to communicate from deep below to other sperm whales for either the purpose of mating or for assistance if their battle has not gone their way. A slight caution, the audio file is fairly loud so you should lower your volume if it is too loud.
