Marine ecologist Matthew Savoca, from Stanford University, is the lead author of a study that looks at how much food these giant mammals actually consume. Previous estimates of their food intake was largely based on just a few measurements, so the team looked at data from 321 tagged whales sized between 30 and 100 feet that lived in the Atlantic, Pacific and Southern Oceans.
And whales produce a lot of poop, which feeds life forms at the bottom of the food chain.The study suggests that if whale populations were restored, and levels of phytoplankton increased accordingly, over 200 million metric tons of carbon could be absorbed and stored in ocean systems. These benefits could also increase year on year, the team says.

The amount of food a whale consumes in a day varies depending on the species of whale. Some smaller species, such as the dwarf sperm whale, may only eat a few pounds of food per day. Larger species, like the blue whale, can consume up to 8,000 pounds of food in a single day.
Whales are carnivorous animals and primarily eat fish, krill, and other small marine animals. The specific type of food a whale eats depends on its species and location. Some whales, like the humpback whale, also consume plankton and other tiny organisms.
Whales have a unique way of consuming their food. They use a process called filter feeding, which involves taking in large amounts of water and then filtering out the food through their baleen plates. Some whales, like the sperm whale, also use suction to catch their prey.
The amount of energy a whale needs to consume to survive varies depending on its size and species. Larger whales, such as the blue whale, require more energy to sustain their massive bodies and may consume up to 40 million calories per day.
Whales have the ability to go for long periods of time without eating, especially during migration or breeding. Some species, like the humpback whale, can survive for up to 6 months without eating. However, it is important for whales to consume enough food to maintain their health and energy levels.
