Waves of excitement roll through the arena as walls of water hit the splash zone. Entertainers leap and dive in response to the crowd's cheers. Initially, the dolphins' smile appears to reflect the mood of the public, when in reality the fixed expression protects a multimillion-dollar industry. The TV show Flippers has created a phenomenon as dolphins have become in demand for entertainment, however, their world is not one of entertainment. Humans are not the only species capable of deception, and dolphins' facial façade hides their inner turmoil. Amusement parks that display dolphins as toys for our entertainment exploit the animals to the point of compromising their physical and mental health. Dolphins are acoustic animals. They rely heavily on their ability to hear and have highly adapted sonar, so much so that dolphins can literally see your heartbeat underwater (The Cove). In fact, much of their brain is dedicated to detecting, interpreting, and producing sound (Bearzi 141). So, when crammed into an arena with thousands of screaming spectators, dolphins experience sensory overload. The stress caused by their environment causes ulcers and can kill them. Dolphins experience suicidal tendencies when under pressure; each of their breaths is conscious, so eventually they simply stop trying to breathe. One of their brain's greatest capabilities, their advanced sonar, is often the cause of their death. This is true not only in captivity. The dolphin entertainment industry created the initial demand for dolphins and currently drives the dolphin hunting industry. Japan alone captures, consumes and exports the largest quantity of dolphins; the small coastal city of Taiji, in particular, is the largest provider of pediatric and adolescent health services 40(8) (2010): 186-215.
