Here's why:
* Krill are abundant: Krill are tiny crustaceans that live in massive swarms, providing a readily available food source for baby whales.
* Nutritious and easy to digest: Krill are rich in fat and protein, essential for the rapid growth of young whales. They are also relatively soft and easy to digest, making them ideal for young mouths.
* Mother's milk provides initial nutrition: For the first few months of life, baby humpback whales rely entirely on their mother's milk. This milk is extremely rich in fat and protein, providing all the necessary nutrients for their initial development. As the calves grow, they gradually transition to feeding on krill.
While krill is their main diet, baby humpback whales may occasionally eat other small creatures like copepods, small fish, and squid. This diversification helps ensure they receive a balanced diet.
