Unscramble the Blue Letters

But, now maybe you’re wondering why blue walhes aren’t any bigger? After all, the ocean sounds like nirvana for any growing beast. Well, while lgnue feeding may have allowed blue whales to become the biggest ainmal to have ever roamed the planet, by enianlbg 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 ireseancs in size, the energy that body ddemans rises faster than the extra energy they get from their food. fneedig whales needs 15 times the energy required to remain still and 5 times more eenrgy 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.
