How much do baleen whales eat in a day?
The new study has observed that baleen whales can consume as much as 16 tonnes of food per day, which constitutes as much as 30% of their total body mass.
A recently published study in Nature has established that baleen whales, the largest animals on the planet, eat thrice or even more the amount of food than previously thought.
The study, conducted primarily in the Southern Ocean, monitored multiple individuals from seven baleen whale species – humpback, fin, blue, minke, right and bowhead and the Bryde’s whale – as they went about their daily business.Baleen whales are so named because they have bristles (baleens) inside their mouth in which their prey (krill) gets stuck. Their close relatives, from the order Cetacea, are toothed whales that have teeth instead of bristles.
Whales were tagged with sensors that tracked their movements, and acoustics were used to identify places where their prey was concentrated.
The methods used are notable as it is the first time that whale movement and diet could be empirically monitored. Earlier studies employed examining the contents of the stomach of killed whales or by employing mathematical models based on metabolic rates of baleen whales. Both these methods suffered veritable disadvantages.
Direct measurements of stomach contents were often done during specific times of the year, which, however, gave a “biased” picture. Some even tried to fill the stomach up with water or gas, but the elasticity of the stomach membrane decreases significantly upon death. As for mathematical models, the metabolism rates involved were often ‘assumed,’ or taken from some captured toothed whales or dolphins.
The new study has observed that baleen whales can consume as much as 16 tonnes of food per day, which constitutes as much as 30% of their total body mass.
Prior studies, researchers maintain, have grossly underestimated the gargantuan appetites of the largest aquatic mammals, wherein “even their highest assumptions…underestimates reality”.
Generalist whales like fin and humpback, as opposed to specialist ones (the blue, right and bowhead whales), may be better buffered against the effects of climate change on marine life, the authors argue.
Different feeding strategies
The researchers highlight differences in the feeding strategies of these species as well. The right and bowhead whales prey on crustaceans by moving through a swarm of crustaceans with an open mouth, a strategy called ‘ram’ or ‘continuous’ feeding.
Another strategy, called ‘lunge’ feeding, involves discrete jumps (lunges) at prey colonies. Lunge feeding is exhibited by the blue, fin and humpback whales. A single whale adopting a lunge strategy can filter up to 17000 cubic metres of water a day, while a ram feeding tends to process four times as much.
Whales and iron cycle
These findings are particularly important as whales are apex predators in food chains they operate and therefore render important ecosystem services and functions.
The foremost among these is the marine iron cycle. Most iron in the ocean exists in biomass. One of the largest reservoirs of iron in the ocean is krill. Krill populations constitute nearly 24% of the total iron in surface waters, an earlier study has established. Upon devouring krill, whales defecate iron-rich faeces. These are then eaten by the planktonic community, which are then, in turn, eaten by krill. And the cycle goes on.
A 2010 study estimated that the amount of iron in whale faeces can be “ten million times that of Antarctic seawater”, while the present study asserts that whales could recycle 7000 to 15000 tonnes of iron each year.
The authors also highlight how whales play the role of ecosystem engineers by mixing iron in the water by virtue of their sheer movement.
This also explains the ‘krill paradox’ whereby it was observed that krill populations actually declined during the whaling years (1910-70), whereas the prey population usually explodes in the absence of a predator.
Even the numbers of competing predator species, which were expected to increase with whaling, have either declined or remained the same (essentially because their food source, krill, was declining).
“Encouraging cetacean populations to recover may restore ecosystem function lost in the 20th century and lead to enhanced oceanic productivity,” authors hope, even as they acknowledge that twentieth-century whaling reduced baleen whales populations by more than two-thirds.

Remembering Birsa Munda on Janjatiya Gaurav Divas
L Murugan writes: He was one of the tallest icons of India’s freedom movement and his contributions, along with others who were part of the struggles organised by tribal communities, must be acknowledged
As India celebrates Azadi Ka Amrit Mahotsav, one name stands tall among the galaxy of stars who fearlessly worked for the freedom of the motherland against the oppressive British Raj — Bhagwan Birsa Munda. Birsa Munda lived a short — just 25 years — but valiant life. His life story, full of gallant efforts to fight injustice and oppression, represents a strong voice of resistance against colonialism.
Born on November 15, 1875, in Ulihatu village in present-day Jharkhand, Birsa spent his childhood in abject poverty in a tribal Munda family. This was the time when the exploitative Raj started penetrating the deep jungles of Central and Eastern India, disrupting tribals living in harmony with nature. The Britisher introduced a feudal zamindari system in the Chhota Nagpur region, destroying the tribal “Khuntkatti” agrarian system. The Raj brought in the outsiders — moneylenders and contractors, as well as feudal landlords — who aided the British in their exploitation. The unrelenting missionary activity continued with the active support of the Raj, insulting and interfering with the religious-cultural ethos of Adivasis.
During the 1880s, Birsa closely witnessed the Sardari Larai movement in the region, which demanded the restoration of tribal rights through non-violent methods like sending petitions to the Raj. However, the oppressive colonial regime paid no heed to these demands. The zamindari system soon reduced the tribals from the status of landowners to that of labourers. The feudal setup intensified the forced labour (veth bigari) in the forested tribal areas. The exploitation of tribals now reached a breaking point.
This culminated in Birsa taking up the cause of Adivasis. He shed new light on the religious domain. He stood firm against missionaries who were belittling tribal life and culture. At the same time, Birsa worked to refine and reform religious practices, discouraged many superstitious rites. He brought in new tenets, prayers and worked to restore tribal pride. Birsa impressed upon the Adivasis the importance of “sirmare firun raja jai” or “victory to the ancestral king” — thus invoking the sovereignty of the tribals’ ancestral autonomous control over the land. Birsa became a mass leader and began to be considered as Bhagwan and Dharati Aba by his followers.
Birsa knew who the real enemy was — in addition to the dikus, it was the oppressive Raj. He was clear that “abua raj setar jana, maharani raj tundu jana” (let the kingdom of the Queen end and our kingdom be established). Bhagwan Birsa ignited the minds of the masses. The Mundas, Oraons, other Adivasis and non-Adivasis responded to his call and joined the “Ulgulan” or revolt against the colonial masters and exploitative dikus. Birsa asked the people not to pay any rent, and attacked the outposts of feudal, missionary and colonial authorities. With traditional bows and arrows, the tribals of Central and Eastern India waged an effective armed resistance against the British. In doing so, however, Birsa was careful that only the real exploiters were attacked, and the common people were not troubled. Birsa became an image of vitality and divinity. Soon, he was captured by British police and lodged in jail, where he died in captivity on June 9, 1900. But Bhagwan Birsa Munda’s spirited struggle did not go in vain. It compelled the British to take cognisance of the plight and exploitation of tribals, and bring in the Chhota Nagpur Tenancy Act of 1908 for their protection. This Act restricted the transfer of tribal land to non-tribals, giving Adivasis a huge relief and became a landmark legislation for the protection of tribal rights. The British regime also took steps to abolish Veth Bigari or forced labour.
Bhagwan Birsa Munda continues to inspire millions of Indians, 121 years after his death. He is an icon of valour, courage and leadership. He was a leader who took great pride in his rich culture and great traditions, but at the same time, did not shy away from reforming his own faith wherever necessary.
He is one of the tallest icons of our freedom movement. India’s freedom struggle was strengthened by several tribal communities such as Mundas, Oraons, Santhals, Tamars, Kols, Bhils, Khasis, Koyas and Mizos, to name a few. The revolutionary movements and struggles organised by tribal communities were marked by their immense courage and supreme sacrifice and inspired Indians all over the country.
However, established historians could not do justice to their immense contribution to India’s freedom struggle. Our visionary Prime Minister Narendra Modi appealed to all Indians to celebrate Azadi Ka Amrit Mahotsav and to study and understand the valour and sacrifice of many such unsung heroes in India’s freedom struggle. Under his dynamic leadership, for the first time, tribal pride and contributions are being given a fitting tribute by celebrating Janjatiya Gaurav Divas, on November 15 — the birth anniversary of Bhagwan Birsa Munda.
On this Janjatiya Gaurav Divas, let us remember and recognise the efforts of India’s tribal people for the preservation of their cultural heritage and the promotion of Indian values of valour, hospitality and national pride.
