When do Blue Whales start to drink milk?

Note: Instead of krill, the baby blue whale consumes milk during its first 6 – 18 months of birth and can drink as much as 150 gallons of milk per day during its first year. This feeding will continue until the young whale can hunt for food and survive on its own. When these marine mammals hunt for food, the blue whale dives underneath

What kind of food does a whale eat?

This allows them to catch a great deal that is in the water, keep what is food, and then to filter out the rest. Generally they will eat smaller sized fish and other items in the water. On average, a whale will eat 4% of its body weight as long as there is enough food readily available.

Why do blue whales only eat krill at night?

It is typically only during the night that blue whales will feed on krill near the surface of the water because krill generally migrates toward the surface during the night and dives back down into the ocean during the day. The reason krill do this is to minimize potential threats from predators while they feed near…
