Without fins or bones capable of paddling, in terms of appearances, jellyfish may seem like mere drifters of the sea. But even in spite of their major deficits, including the absence of a heart and brains, these invertebrates have an incredible talent for swimming. So much so that no other creature under the sea can quite compete in terms of efficiency and skills. Though their tactics have long been misunderstood, a new study adds to the working knowledge that these brainless creatures are far more clever than we give them credit for.
