As you might have guessed from the topic, I just watched discovery channel. It implied that sharks could be use as tools to help identify impending storms or hurricanes.
How does this happen?
Before a storm, the air pressure usually drops. With it, the pressure underwater also drops. Sharks inherently have excellent barometer-like hair that can sense pressure changes of the environment. Take for instance, sharks like to swim in deep waters, however, when the pressure of the surroundings drop, a 7-foot deep water body will feel like 5-foot deep. This perceived change in water depth encourages the sharks to swim to safer grounds (even away from their homes and to unknown territories).
What scientists discovered is that these sharks have such a good sense of the pressure that they start to make a beeline for deeper waters way in advance of the storm. So far, various storms have been predicted using sharks but surely, none of them were used as the defining factor to evacuate a city.
A quick search in google shows up this article: http://www.dailymail.co.uk/sciencetech/article-544770/Storm-detecting-sharks-weather-forecasters-future.html
I can't find the video that explains it nicely on YouTube. Sorry. Will append it here if I ever come across it again.
So, I was just wondering if other animals had such innate self-defense senses. Have you ever seen your locality free of all animals suddenly? Maybe its time for you to pack up too!
This reminds me of the scene in Harry Potter where all the owls gather outside Dudley's house to post to Harry the letter of admission to Hogwarts.
