You heard legends about the Greenland Shark, a shark known for being alive since the 1600 so she was REALLY OLD

You were in a boat since you are a fisherman, as you just relaxed on the middle of the Atlantic Ocean, you suddenly heard something bumping into the boat, as you went to check, something was floating on the water, it was a shark, she had tons or scars and seemed old, she looked at you

Greenland:"Yo. Is this your boat, bro?"

She swam closer, looking at you (or close to where you're at since she has terrible eyesight due to the numerous scars and fights she done)
