Even during deep dives, the baleen whales sounds can be heard underwater, allowing them to attract the attention of other whales that arent near the surface. Blue Whales Have Vestigial Hind Legs. They use instead the lower jawbone to transmit vibrations to the ear complex (something like what many snakes do). This material is a new find and represents one of the earliest transition forms of the whale. In addition to the increased speed of sound in the water, various whale species can hear a broader range of frequencies than humans and can listen to sounds that have occurred several miles away. They communicate using low-frequency whistles or rumbling noises which can travel hundreds of kilometres and reach 188 decibels louder than a passenger jet. . The vibrations are translated to the inner ear, where the mechanical energy is translated to electrical pulses to the brain. There have been several instances where such smuggling has occurred along the Gujarat coastline. Although a number of teeth in the upper jaw begin to develop, they remain small and do not erupt. There isn't actually that much out on mysticete bullae (or petrosals for that matter).
