By attaching sensors to whales right before they dove, scientists discovered types of feeding processes unique to certain species. For example, rorquals use lunge feeding to engulf enormous amounts of water and prey. They have to time their lunge just right and must feed on rich resources to regain the energy lost. Researches also found that whales that feed on krill open their mouths at peak speed and close it around the time they were back to normal speed. However, humpbacks that feed on fish varied their timing in response to the speed of the fish. This research shows us the impact whales have on ocean resources and will help support conservation efforts.
