Not sure, but they are extremely intelligent. When they are no longer hungry they will sometimes act like they are going to eat the last one. They will toss him in the air and play/scare the last one to death. They will not harm him but soon release him even to the point of throwing the last one back on land. They do not kill for sport. I believe that orcas do participate in 'sport killing', as evidenced by an intact and very dead seal found on the beach on San Juan island. Numerous conical tooth marks from tail to scalp. Skull was crushed. Seal was otherwise intact (not eaten). Why wouldn't they 'sport hunt'-clearly other mammalian predators (ie wolves) do. Seals are competition for the orcas food source. Fewer seals means more salmon for the orcas.
Orcas (aka Killer Whales) eat fish, any birds they can catch, also they eat many types of marine mammals include seals, whales, blue whales, sperm whales etc. They also eat fish like great white sharks and salmon.

Alot. About 10 fish i guess.
several tons a day
A blue whale generally eats about 40 million krill a day, sometimes eating up to 7,900 lbs of krill in a single day.
several tons a day
100 to 500 kg
Its favorite food is "Krill". An Adult blue whale can kill upto 40 million krill per day. They can eat nearly 3500 kilograms of krill in a single day. They need nearly 1.5 million kilocalories of energy per day and so, they nearly eat nonstop. Small fish, crustaceans and squids too get caught when they trap krill in their mouth
humpback whale eats around 5000 krill one day.
Humpback whales are carnivores that eat tiny crustaceans (krill, superba, copepods, etc.), plankton, and small fish (including herring, mackerel, capelin, and sandeel) from the water. They are gulpers: they swim then gulp a mouthful of plankton or fish. An average-sized humpback whale will eat around 5,000 pounds of plankton, krill and small fish each day during the feeding season in cold waters (about 120 days). They eat twice a day.
Well, they have to eat that much or they won't survive/ they won't be satisfied and happy. But I don't think that they eat krill, I think it's plankton...
An average whale eats 2,000 to 2,500 kilograms of food each day.
Well average whale can eat 4 tons of krill a full day :) do you understand better or are u still confused hope not . Good luck!!!
