What kills a blue whale and how do they kill it?

Answer 1

They can die because of old age or some other kind of killer mammmal can kill them. Whalers can kill them either on purpose or possibly by accident. They can die because of food shortage. Maybe of some kind of sickness or diesease.

Answer 2

Hunting of the blue whale stopped in 1977.

Now, the blue whale's only predator is the orca, or killer whale (actually a type of dolphin). Almost a quarter of blue whales have scars from orca attacks, but the blue whale's size (up to 120 tonnes and 60 metres [200 ft] long, bigger than any of the dinosaurs) suggests they are difficult to kill. There is no information on how many are killed by orcas.

Answer 3

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.

They scoop up large quantities of water into their mouth along with krill and other small aquatic creatures and then filters and push the water out. All remaining animals are swallowed.

Answer 4

Blue whales eat krill, which are crustaceans like shrimp, but almost microscopically small. They take them into their mouths with water, and filter them out of the water with baleen plates. Baleen is a material rather like horn, which is arranged in many narrow strips like teeth in a comb, and used as a sieve. A blue whale can eat 40,000,000 krill in one day.
