What do whales look like?

Whales can be many different shapes or sizes! Most whales are a blue-green color, which is the same color as the ocean. Their color helps them camouflage  themselves. 

Whales also have a blowhole  on the top of its head. They breathe through their blowhole . When whales come to the surface for air, the blowhole  spouts out vapor

Scientists can tell types of whales apart by the shape of their spouts!
