The pygmy blue whale is the only one of the three identifiable subspecies to be found regularly in tropical waters. It occurs from the sub-Antarctic zone to the southern Indian Ocean and southwestern Pacific Ocean, breeding in the Indian and South Atlantic oceans, and travelling south to above the Antarctic to feed, [4] [7] although they very rarely cross the Antarctic Convergence.
A thrifty study uncovers a wealth of data about one of the world's largest and most elusive species.

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. [20] The frequencies it uses are mostly ultrasonic, [16] peaking around 125 kHz. [20] The clicks from their echolocation has been recorded to last an average of 600 microseconds.
