The ocean is very vast, and there is still such a huge part of it that has not been discovered by us. There are many, but special creatures beyond the midnight zone. Because of global warming, overfishing, and other reasons, changes in water temperature, food sources, and oxygen levels. These changes can disrupt deep-sea ecosystems, alter marine food webs, and increase the risk of species extinctions.

One of these fascinating creatures is the blue whale, 

Blue whales have a long body and generally slender shape. Their mottled blue-gray color appears light blue under water—hence their name, the blue whale. 

Also, Blue whales are crucial to marine ecosystems as - 

They control the krill population, stabilize the food web, and contribute to the ocean's overall health.

But the problem is that the number of these innocent creatures is decreasing drastically. Now these creatures are said to be in the range of endangered animals, and it is our responsibility to take care of their survival so they don't go extinct.
