How do marine animals communicate? 

I chose this article because I love to learn about animals and decided to share how marine animals including whales and dolphins communicate through their environment. I found a few things that caught my attention in this article, one being that marine animals can use several combinations of complex noises, like clicks, whistles, and squeaks. Some whales even make sounds called songs which can last for 20 minutes and can change pitches from high to low. 

This amazes me because when I think of an ocean I think of a peaceful, quiet place, but really it's filled with sound all around us. I do agree with this article because there has to be some way marine animals communicate and this seems very logical. Learning about animals and the way they communicate definitely make me want to learn more and more about this topic. 

My topic affects the world because it is important to know that underwater machines, boats, submarines, and oil drilling are interfering with these animals communication towards each other. In the mix of all the noises their sonar gets mixed up and this can effect communities of dolphins or whales by separating them or putting them into harm. In the article, it was stated that the U.S Navy has taken that into consideration and turns off their sonar when they see marine animals visible or on a tracking machine.
