The newly discovered Perucetus colossus, an ancient species of whale, is thought to be one of the largest and heaviest animals on record, reports a study published in Nature. Estimates of its size and weight, based on a partial skeleton, rival those of the blue whale, which was previously thought to be the heaviest animal ever to exist. The findings suggest that the trend towards gigantism in marine mammals may have begun earlier than previously thought. Reconstruction of Perucetus colossus in its coastal habitat. Estimated body length: ~20 meters. Credit: Alberto Gennari
