Whales, immense marine mammals, captivate human interest with their size and complex behaviors. Many people often wonder about the terminology for their offspring. Understanding the early life of these fascinating creatures begins with knowing what their young are called.
The Common Name for Baby Whales
A baby whale is specifically known as a calf. This term is not unique to whales but is widely applied across many large mammalian species. For example, the young of cows, elephants, hippos, and even giraffes are also referred to as calves. This shared nomenclature reflects a common biological characteristic among these diverse animals.
The use of “calf” for the young of large mammals typically signifies an offspring that is born relatively large and often requires an extended period of parental care and nourishment. Whale calves, like their terrestrial counterparts, are born at a considerable size and are highly dependent on their mothers for sustenance and protection during their initial developmental stages. This consistent naming convention helps categorize and understand the early life stages of these substantial creatures across the animal kingdom.
Life as a Young Whale
Whale calves typically enter the world tail-first, a birth orientation believed to prevent drowning during the birthing process. Immediately after birth, the calf must quickly learn to swim to the surface to take its first breath. The mother whale plays a direct role in assisting her newborn, often nudging it towards the surface.
These young whales rely entirely on their mothers for milk, which is exceptionally rich in fat, allowing for rapid growth. A calf will nurse frequently, gaining hundreds of pounds daily in some larger species. This high-calorie diet supports their rapid development, enabling them to build blubber reserves necessary for insulation in cold ocean waters.
Maternal care extends beyond feeding, encompassing protection from predators and instruction in essential survival skills. Whale calves remain close to their mothers, benefiting from their guidance and learning migratory routes and foraging techniques. This close bond ensures the calf’s survival and prepares it for an independent life in the vast ocean environment.

These young whales rely entirely on their mothers for milk, which is exceptionally rich in fat, allowing for rapid growth. Whale milk can contain between 13% and 53% fat, much higher than land mammals, enabling quick development. A blue whale calf, for instance, can gain approximately 90 kilograms (200 pounds) each day. This high-calorie diet supports their rapid development, enabling them to build blubber reserves necessary for insulation in cold ocean waters.
