Perucetus Colossus: The Giant Whale

The video explores the discovery of Perucetus colossus, a potentially larger whale than the blue whale, found in Peru. It discusses the challenges in estimating its size due to its unique skeletal structure and compares it to modern whales and manatees. The video speculates on its lifestyle, suggesting it might have been a slow-swimming, coastal scavenger. The discovery raises questions about the limits of animal size and suggests that Perucetus might be the largest animal ever, though uncertainties remain.
