The flesh of a Greenland shark is poisonous. This is due to the presence of the toxin trimethylamine oxide, which, upon digestion, breaks down into trimethylamine, producing effects similar to extreme drunkenness. Occasionally, sled dogs that end up eating the flesh are unable to stand up due to the neurotoxins. Similar toxic effects occur with the related Pacific sleeper shark, but not in most other shark species, whose meat is often consumed fresh.[15]
However, it can be eaten if it is boiled in several changes of water or dried or fermented for some months to produce Kæstur Hákarl, often Hákarl for short. Traditionally this was done by burying the shark in boreal ground, exposing it to several cycles of freezing and thawing. It is considered a delicacy in Iceland and Greenland.

Greenland Shark
The Greenland shark (Somniosus microcephalus) is a shark that must live in the sea, and breathes through gills. A reptile is able to breath air using lungs and can live in or out of water.
While the greenland shark may be dangerous in the fact that it is a shark that could easily eat a person whole, it isn't too common to run in to any. Another fun fact about the greenland shark is that it's skin is poisonous! That makes them even more dangerous!
