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.
Brain Exercise with Dr. Kawashima where every game will be played while monitoring its effect on the brain of the player. Brain Exercise with Dr. Kawashima The game is structured around a set of 15 minigames which are used in the different game modes. After selecting a profile (there are 3 slots for different users) a cel-shaded 3D Dr. Kawashima will accompany the player when browsing the menus and will explain the minigames. After playing each minigame in any of the game modes, player's performance is rated via a ranking of items found in nature, which includes creatures such as plankton, a whale or a
