Every year tens of thousands of marine mammals are killed all over the world, with over twenty thousand small cetaceans killed in Japanese waters alone (Butterworth et al., 2013). These small cetaceans include various species of small whales, many dolphin species and some porpoises. They are killed in various manors, ranging from accidental ship strikes to the more morally controversial yearly drive hunts. As you may know nearly all cetaceans use some sort of sound production in order to navigate waters, communicate with other individuals and groups of their respective species as well as capture prey (Brownell et al., 2008). An example of this is the variety sounds produced by bottlenose dolphins (Tursiops truncatus) when exploring and foraging. These types of noises vary from echolocation, whistles and pops according to Nowacek (2005) which aid in location of prey, and communication when hunting in groups. Bottlenose dolphins are one of the most well-known cetacean species (Bearzi et al., 2008). They inhabit various marine habitats across the world including just about any region with a warm-temperate to tropical ocean climate (Reeves et al., 2002). Just like many other cetaceans they are well known for inhabiting coastal areas, which makes them particularly vulnerable to human interaction and threats they wouldn’t necessarily face on the coast of uninhabited lands (Wilson et al., 2008). This use of sound is an extraordinary adaption for life under the sea, unless of
