Rare footage of a Greenland Shark (Somniosus microcephalus)
Greenland Sharks are the longest lived vertebrate, with lifespans of 400+ years, and are the largest arctic fish. The majority of Greenland Sharks are blind due to parasitic copepods that attach themselves to the eye. They are generalist scavengers, eating carcasses of animals that have fallen to the seafloor. They are rarely seen by humans due to their deep habitat.

The Great White Shark is the largest species of mackerel shark, averaging 3.5 - 4m long in males and 4.6 - 4.9m in females, with some females reaching 6.1m in length. Young Great White Sharks eat bony fish, rays, and other small sharks. Full grown Great Whites are capable of preying on small cetaceans, otters, sea turtles, seabirds, and pinnipeds.
