well first it makes sound waves and if the bounce of they know that its prey is near
the blue whale doesn't have no predators unless a group of killer whales attack it
YOU! Humans are the largest threat to the blue whale. Sucks, I know.
the prey of a whale is krill plankton fish
I don't think that they do. If you are referring to within the animal kingdom, they are the largest animal so nothing can usually take them down. But if you mean people, I don't know that any culture normally does.
The blue whale diet consists almost exclusively of krill, a small oceanic creature that generally measure in at a measly 1-2 centimeters. This is surprising, considering the massive size of the blue whale.
hey, i don't know so why ask me? Check something else, k?
Blue whales are filter feeders; they filter small organisms such as krill, sardines, etc, out of the water, by use of their baleens.
It's unlikely that killer whales would ever try to attack a blue whale due to the epic difference in size. Orcas would most likely avoid a blue whale and would go after prey smaller than themselves. Basically, I dbout a killer whale could harm a blue whale.
The largest animal to exist on planet earth was the blue whale, but know they are starting to go and there is the dinosaur, Hope this was what you were expecting
Probably spit you out: An average blue whale esophagus is roughly 4 inches in diameter, making humans impossible to eat whole.On top of that, blue whales don't have teeth, but instead baleen plates, which filter zoo plankton (their common prey) from the salty ocean water.
The blue whale is a baleen whale.
i actually dont know lol
