ANSWER: It keeps them warm when they go under water in the cold ocean.
Yes, orcas (killer whales), false killer whales, pilot whales, bottlenose whales, bottlenose dolphins, and marlins eat tuna fish. Also,sperm whalesand sharks occasionally eat tuna fish but they tend to be too slow to catch up to tuna fish in most situations. The giant, filter-feeding whales and sharks can only eat small fish (usually not small tuna fish) and other small creatures in the ocean.
The relationship between whales and physics is that whales produce acoustic sounds for communication which can be picked up on sonar equipment. This is part of the process of under-water acoustics.
Killer whales, also known as orcas, are not officially endangered.There are a great many threats to the killer whale, and some local populations are definitely endangered or threatened, but as a speices, they are classified as "data deficient". This means there are different species of killer whales, and some of them may well be in need of protection. For example, in late 2005, the Southern Resident Killer Whales, which are a group of populations in the eastern North Pacific Ocean, were placed on the US Endangered species list.Killer whales have been exploited for their meat, hides, blubber and internal organs for a long time, but never on a large-scale basis. Habitat loss and pollution remain problems for the killer whales.
killer whales are mammels there for need to come up to take in air.fish however can breath under water.fish also lay eggs but killer whales and dolphins give birth to a smaller version of themselves
in the wild they can be very gentle someone was seen swimming under them but in captivity when there are in their pond they aren't so happy
