Tag: Polar bear diet

The blue whale, the largest animal on Earth, can take in an astonishing 457,000 calories with a single mouthful of krill. However, the answer to the question of what animal has the highest calories depends on whether you're asking about total daily intake or caloric density per gram. This article explores both perspectives, revealing the incredible energy-storing adaptations of various creatures.

Scientists have determined that an average adult polar bear requires approximately 12,000 calories per day, far more than most people might expect, especially given their often-sedentary hunting strategy. This high metabolic rate is crucial for maintaining their massive body weight and insulating fat in the frigid Arctic environment.
