Narwhals swimming in the ocean
#1
http://www.bbc.com/news/science-environment-42259289

According to the article, when narwhals in the arctic are scared or posed to a threat, their response is to freeze until the threat passes. What this does is makes the heart of the narwhal go from beating 60 beats per minute, to 15-20 second intervals between each beat. With the arctic ice melting, this could potentially pose a big threat to narwhals due to new disturbances such as ships or other noise. I believe that we should take this problem into our hands and create safeguard areas for these animals along with other marine life. Since these narwhals freeze when threatened creating reduced oxygen supply for these mammals, even allowing certain regulations to prevent this from happening would be ideal in order to prevent these situations from happening or at least reducing the percentage from happening.

Narwhals have not had a lot of exposure to human disturbances which are starting to arise as the ice in the Arctic is melting. The noise pollution from the ships that are present is enough to pose as a threat to them. The problem is how the narwhals respond though. Its response can cause a biological problem for them in the long run. As it flees its heart rate decreases which is bad because as said by one of the scientists,"if animals move quickly but their heart rate is very low this could deprive their brain oxygen and leave them disorientated". I suggest finding a different route the ships can use. Or if possible because of the new inventions and scientific discoveries, we can find a way to regulate their heart rate to be advantageous for the narwhals. #savetheseaunicorns
