description Blue Whale Overview

The blue whale is a marine mammal and the largest animal ever recorded on Earth, reaching lengths of up to 30 meters and weighing approximately 180 tonnes. As a baleen whale, it filters its primary food source, krill, from the water using specialized bristle-like plates. Found across all major oceans, this endangered species was driven to the brink of extinction by commercial whaling during the 20th century. Despite international protection, blue whale populations remain a fraction of their pre-whaling numbers.
