Blue Whales actually have a lot of different adaptations. One is that, instead of teeth, they have small fingernail-like material called baleen on their upper jaws. This allows them to take a big gulp of water, and, using their huge tongue, push out the water and swallow all the krill that was in it. They also have something called blubber, which is what keeps them from sinking-blubber is less dense than water, so it floats. Blue whales' size actually helps them, as well. They seem quite threatening to predators, and this helps keep quite a few of them away. And that's not all. They can hear and communicate to other whales up to 1,000 miles away. There are many more, but these are just a few
