Humpback whales are enormous creatures, often stretching up to 16 metres long and weighing around 30 to 40 tonnes—about the size of a full-length. They have a distinctive body with long pectoral fins, knobbly heads, and a small dorsal fin, giving them a unique silhouette in the ocean. Their massive flippers can be up to a third of their body length, helping with agile turns, while their broad, powerful tails (flukes) are often seen when they dive deep. Like all mammals, humpback whales breathe air, are warm-blooded, give birth to live young, and nurse their calves with milk. Humpbacks feed by filtering tiny shrimp-like crustaceans, called krill, along wth small fish through baleen plates in their mouths. These whales travel thousands of kilometres every year from cold feeding grounds near the poles to warm tropical waters where they breed and give birth. Newborn calves stay close to their mothers for protection and to nurse, often gaining tens of kilograms each day from their mother’s rich milk. Once the young are strong enough, they make the long journey back to the polar regions to feed on the plentiful supply of krill and small fish and prepare for the next years migration. Humpback whales are truly one of nature’s wonders — graceful, powerful, and full of surprises. From their epic migrations to their playful splashes and beautiful songs, these gentle giants continue to inspire awe in everyone lucky enough to see them.
