Pygmy Sperm Whale
Rarely seen and poorly understood, these deep-diving cetaceans grow to just 3 meters long. They produce clicks between 60-120 kHz using a spermaceti-like organ similar to their larger cousins. Pygmy sperm whales hunt squid and fish in the darkness of the deep ocean. They remain one of the most elusive marine mammals. Scientists know little about their behavior due to their deep habitat and shy nature. Their echolocation likely plays a crucial role in their solitary hunting strategy.
