10 Hakarl
A previous list covered the dangers of Greenland Sharks to humans, including Inuit hunters who may be turned over in their Kayaks. However, a more subtle risk is posed by Greenland Sharks – to your palate, and health. Greenland Sharks lack the ability to urinate, causing massive amounts of ammonia and trimethyl oxide to instead be processed through the tissues of these sharks. The ever enterprising Greenland natives have devised a traditional meal known as Harkal, which is basically aged shark flesh. Not only is the smell of the shark flesh nearly unbearable, but the consumer faces potential organ strain, intoxication and sickness from the poisons still present in the flesh.
