a blue whale is bigger than a redwood tree
with a blow hole. A blue whale surfaces a breathes through it's blowhole, and it can hold it's breath for hours.
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.
Yes the killer whale is an apex predator. They will eat anything from Great White Sharks to birds and they have been even seen trying to take down blue whales !
being cut down
A Big Percent!
No blue whales do not hunt dolphins. Blue whales are filter feeders and don't have any teeth to take down a species of dolphin. But it is probably the other way round because killer whales the largest member of the oceanic dolphin family delphinidae have been known to try and kill blue whales. Hence the name killer whale they kill whales
because they are very big and ugly!
Depends on what you mean by breathe underwater.No mammal can breathe unaided underwater.Us humans can kinda-sorta breathe underwater by using technology to bring some surface conditions(=breathable air) with us into the depths.We have to use snorkels or scuba gear, but we still win.
They were moved or chopped down.
The blue whale is the fastest, the sperm whale is not far behind and the right whale is the slowest. The blue whale would be the only one with a well defined fin (a dorsal fin) on it's back. A sperm whale (like all toothed whales and dolphins) has a single blowhole at an angle on the top/front part of its head, so it has a single blow that comes up at an angle. A right whale (like all baleen whales) has a double blowhole on the top of its head. It has a double blow. A blue whale, even though it also has a double blowhole has a high and straight blow. There are several good field guide books that show the difference between the blows of different types of whales.

The blue whale has a long, streamlined body. It has two long, tapered flippers and a small dorsal fin about three-fourths down its back. It is mottled grayish-blue in coloration. It has a U-shaped rostrum (snout) and a raised splashguard in front of its two blowholes. At the end of its tail its has two flukes, which help propel it through the water.
