A Baby Blue Whale Gains 90 Kilograms Every Day
Newborn blue whales drink up to 150 gallons of nutrient-rich milk daily, allowing them to gain roughly 90 kilograms—about the weight of an adult human—each day. This rapid growth helps them survive in cold ocean waters.
💡 Fun detail:
At birth, a blue whale calf is already the size of a full-grown elephant and keeps growing for the first decade of life.
