Communication and Perception
Although little is known about how Mesoplodon perrini communicates, research on other species of mesoplodont whales indicates that they have the ability to echolocate. A 2004 study involving tagged Mesoplodon densirostris found that these animals are very vocal, most frequently emitting ultrasonic clicks that are well outside the range of human hearing. This research also revealed that these whales only emit clicks when they are below 200 meters depth, where they most commonly forage.
