From the Ted Talk by Asha de Vos: Why are blue whales so enormous?
Unscramble the Blue Letters
But, now maybe you’re wondering why blue whales aren’t any bigger? After all, the ocean sounds like nirvana for any growing beast. Well, while lngue feeding may have allowed blue wealhs to become the biggest anmail to have ever roamed the planet, by enabling them to feed efficiently in dense prey patches, it isn't cost free. Scientists compared all the ctsos involved with lunge fdenieg to the energy gnaied from the krill they eat. What they found is that when the whale’s body increases in size, the energy that body dnemads rises faster than the extra energy they get from their food. Feeding whales needs 15 times the egreny required to remain still and 5 times more energy than used when swimming.

Original Text
But, now maybe you’re wondering why blue whales aren’t any bigger? After all, the ocean sounds like nirvana for any growing beast. Well, while lunge feeding may have allowed blue whales to become the biggest animal to have ever roamed the planet, by enabling them to feed efficiently in dense prey patches, it isn't cost free. Scientists compared all the costs involved with lunge feeding to the energy gained from the krill they eat. What they found is that when the whale’s body increases in size, the energy that body demands rises faster than the extra energy they get from their food. Feeding whales needs 15 times the energy required to remain still and 5 times more energy than used when swimming.
