At birth, baby humpback whales, also known as calves, measure around 10 to 15 feet (3 to 4.5 meters) in length. Despite their considerable size, they are relatively small compared to their adult counterparts. However, their growth rate is astonishing. Within the first year, a baby humpback whale can add an impressive 1 ton (907 kilograms) per month to its weight.
By the time a baby humpback whale reaches adulthood, it can measure anywhere between 40 to 50 feet (12 to 15 meters) in length. The size of an adult humpback whale can vary, with males usually being slightly smaller than females. They can weigh up to 40 tons (36 metric tons) or even more.
These impressive dimensions are not solely attributed to their length; humpback whales also possess a massive girth. Their bodies are robust and streamlined, allowing them to traverse vast distances during their annual migration.
