ScienceTechyNews: The limits of ocean heavyweights: Prey curb whales' gigantic size

Scientists collected data from hundreds of feeding whales, allowing them to determine how much energy species of different sizes invest to capture their prey and which of these species reap the greatest rewards for their efforts. Their findings reveal that body size in all whales is limited by the availability of their prey, but only filter-feeding whales have evolved a feeding strategy that drives them to achieve the largest body sizes to have ever evolved.
