Although humans are not a sought after meal for sharks, surfers can often be confused for tasty seals. And the shark likes to take test-bites before deciding whether or not to continue its attack. That first bite alone can be deadly.
But sharks are also just a part of our ecosystem and can be a barometer for the health of our oceans. And as it turns out, sharks also have a few tricks up their jaws when it comes to saving energy. In turn, there are a few things that we could learn from the sharks - and even a number of ideas that we can borrow from them to act against climate change.
The formula is essentially to use the best angle of dive to resurface and eat with using the least amount of energy. Genius!
