They store extra fat reserves in their blubber during the summer when the feeding is good. This allows the whales to go months without food.
Krill swarms are easy 2 million strong. so imagine of a whale runs into a few swarms. The gorge themselves oin it, whales can eat 3 tons of krill a day! But also whales store alot of fat. A mother whale will taker her calves to safe water for the calf to grow strong and can so 5 months with out eating. If you are really interested you should watch planet earth shallow seas show.
Dophin and whales never becomes mammals, because regarding the creature science ,delivery and breast feedings are considered in the case of mammals. but these two creatures are not having breast feeding.
Orcas, also known as killer whales, are actually a type of whale themselves. They are the largest species of dolphin and are known to prey on other types of whales, such as baleen whales. This makes them apex predators in the ocean.
Whales and dolphins use biosonar for communication and also for navigation .

The truth.....they can't. We ALL need to work together to make a better environment for the whales. GO WHALES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales and benefit from the whale's movement and access to food particles, without causing any harm to the whale.
I don't think they have a way of protecting themselves. They are usually eaten by whales anyways and there isn't much protection from a whale if you are as small as krill. They can protect themselves but not against whales. They protect themselves by traveling in large numbers.
They relieve themselves in the ocean.
Larger whales tend to eat smaller whales. Other animals that are known to eat small whales include orca and shark. Large whales are not predated but predators themselves.
An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales and benefit by getting a free ride through the water and access to nutrients. The whales are not significantly affected by the presence of the barnacles.
On occasion but often in schools or pods
