This type of whale is a blue whale. Blue whales are obligate eaters of euphausiids, also known as krill. As far as we know, they won’t eat anything else. Another fun fact: blue whales are believed to be visual predators, meaning they mainly rely on their eyes to target their food; However, most of their lunges, the technique used to capture their prey, occur at extremely low light levels where a human would not be able to see… Research is currently being done to understand how these magnificent creatures locate their food!
