When it comes to the incredible growth rate of baby caribous, it is truly astonishing. Weighing approximately 13 pounds at birth, a baby caribou will double its weight in just a matter of weeks.

The rapid weight gain of these adorable creatures is essential for their survival in the harsh arctic environment they call home. With such extreme weather conditions and limited food resources, baby caribous need to grow quickly to have a better chance of surviving and thriving.

Within the first few weeks of their lives, baby caribous will consume their mother's nutrient-rich milk, which is packed with essential proteins and fats. This milk provides them with the necessary energy to support their rapid growth. As they continue to nurse, these baby caribous will gain weight at an astounding rate, doubling their birth weight in just a few short weeks.

It's not just the milk that contributes to their rapid weight gain. Baby caribous are born with a unique adaptation that helps them digest their food efficiently. They have a specialized digestive system that allows them to extract maximum nutrients from their diet. This, combined with their high metabolic rate, enables them to convert food into energy quickly, leading to substantial weight gain.

As they grow, baby caribous also start to nibble on vegetation, gradually transitioning from a milk-only diet to a more diversified one. This change in diet further aids in their weight gain and overall development. They will continue to consume a combination of milk and plant-based food until they are old enough to exclusively feed on vegetation.

By doubling their weight in just a matter of weeks, baby caribous are equipped with the strength and stamina needed to survive in the harsh Arctic climate. Their rapid growth ensures that they can keep up with the herd, evade predators, and endure long migrations in search of food and better grazing grounds.
