Pygmy sperm whale significant concentration of magnetite crystals, which suggests that "K. breviceps" can navigate by magnetoreception. Studies have also shown that compared to the sperm whale, the pygmy sperm whale brain has significantly fewer neurons, which may be connected to a decreased complexity in social interaction and group-based living. Like all toothed whales, the pygmy sperm whale hunts prey by echolocation. Sound produced for echolocation by many odontocetes come in the form of high frequency clicks. The frequencies it uses are mostly ultrasonic, peaking around 125 kHz. The clicks from their echolocation has been recorded to last an average of 600 microseconds.
Mesoplodont whale what effect this has on the population. Longman's beaked whale ("Indopacetus pacificus", also known as the Indo-Pacific beaked whale or the tropical bottlenose whale) was originally assigned to "Mesoplodon", but Joseph Curtis Moore placed it in its own genus, "Indopacetus", a taxonomic assignment which has been followed by all researchers. Two extinct species of "Mesoplodon" are known, "M. posti" and "M. slangkopi". Mesoplodont whale Mesoplodont whales are fifteen species of toothed whale in the genus Mesoplodon, making it the largest genus in the cetacean order. Two species were described as recently as 1991 (pygmy beaked whale) and 2002 (Perrin's beaked
