Whales are some of the largest creatures on Earth, and they need a lot of food to sustain themselves. But why do they need so much food?
There are a few reasons for this. First, whales are warm-blooded animals, which means that they maintain a constant body temperature. This requires a lot of energy, which they get from food. Second, whales are marine mammals, which means they live in the water. This means they have to constantly swim to stay afloat, and this takes a lot of energy. Third, whales give birth to live young, which means they have to provide food for their offspring. And finally, whales have a very high metabolism, which means they burn through calories very quickly.
All of these factors contribute to the fact that whales need a lot of food. They typically eat krill, small fish, and squid. They can eat up to 3% of their body weight in food each day! That’s a lot of eating!
