Humpback Whales Seen Bottom-Feeding

Footage from a crittercam recently revealed that humpback whales frequently bottom-feed—a habit that was previously unknown.

Humpback whales are better known for their tactic of creating nets out of bubbles which they then leap through catching mouthfuls of fish. When computer scientist Colin Ware of the University of New Hampshire analyzed data from tags that had been attached to humpbacks, he was surprised to see that they were spending more time on the sea floor.

Ware and his colleagues watched again and again as the whales swam to the bottom, turned on their sides, and skimmed just above the bottom for prey. They hope to study this behavior more in order to find out if whales prefer a certain kind of seafloor—gravel or sand—when feeding.
