description Pygmy Blue Whale Overview
The pygmy blue whale is a subspecies of the blue whale scientifically classified as Balaenoptera musculus brevicauda. It is physically smaller than the Antarctic blue whale, generally reaching maximum lengths of around 24 meters, and is distinguished by its proportionally shorter tail stock and larger head relative to its body size. This subspecies predominantly inhabits the northern Indian Ocean and the southwestern Pacific Ocean, favoring warmer, temperate, and tropical waters. Like other blue whales, it is a filter feeder that survives primarily on a diet of small, shrimp-like crustaceans known as krill.
