The pygmy sperm whale (Kogia breviceps), is a species of small cetacean belonging to the family Kogiidae. It is one of the smallest members within the toothed whale suborder, Odontoceti. Adult individuals typically reach lengths between 2.7 to 3.5 meters (8.9 to 11.5 feet), with females being slightly larger than males.
Pygmy sperm whales have a unique appearance, featuring a stocky body with a bulbous head and a blunt snout. They possess a prominent hump just before the tail and a series of grooves running along the throat area. The skin is dark gray or bluish in color, occasionally with white or light gray patches.
These whales inhabit warm and temperate oceanic waters, mainly found in the Atlantic, Indian, and Pacific Oceans. They are known for their elusive nature and deep-sea diving behavior. Pygmy sperm whales primarily feed on squid and fish, utilizing suction to capture their prey.
When threatened or distressed, pygmy sperm whales may release a reddish-brown liquid, similar to other members of the sperm whale family, which has led to the nickname "junk whale." This defensive behavior may serve to confuse or deter potential predators.
Due to their elusive behavior and preference for deep waters, relatively little is known about the population size and overall conservation status of the pygmy sperm whale. Climate change and human activities, such as pollution and entanglement in fishing gear, pose potential threats to these enigmatic creatures.
