Humpback whales are known for their bubble nets. In Cape Cod Bay, Massachusetts the marine mammals spend the summer blowing bubbles in circles under the water and then lunging through roiling schools of fish for a mouthful of water and sand lance, a skinny, finger-length fish.
If you watched humpbacks only from the surface, you'd think that was how they got all their food. But a team of scientists has been putting tags on the whales to snoop on them underwater. They found something surprising: Humpbacks actually spend a lot of time feeding at the bottom.
