Dr. Joe Roman discusses how the restoration of whales is essential in maintaining the integrity and resilience of marine ecosystems. Great whales are the largest animals in the history of life on Earth, playing an essential role in the structure of the ocean. They prey on fish and invertebrates and are preyed upon by killer whales. After death, their carcasses create unique habitats, upon which hundreds of deep-sea species depend. Whales enhance the growth of marine life by transporting nutrients in the water column and around the globe. Their depletion has likely altered the structure and function of the oceans, reducing the many ecosystem services provided by these enormous ocean dwellers.
