Why Are Blue Whales Called Blue When They Look Grey? - Simple Explanation for 5-Year-Olds

Hi there! Let's talk about blue whales. Blue whales are the biggest animals in the whole wide ocean! Even though they are called 'blue whales,' they sometimes look grey. Let me explain why:

• Colors Can Change in Water: When we see the whale in the water, it might look a little greyish because the water and sunlight change how its color looks.
• Blue Whale’s Skin: The whale's skin is actually a blue-grey color. Sometimes it has little spots that make it look more grey than bright blue.
• Why Called Blue: People named it a 'blue whale' because from far away, and under the water, it looks blue!

So, even if the blue whale looks grey sometimes, it's okay because it's still a big, beautiful blue whale!
