In all seriousness, though, it has everything to do with Will Bednar Ice in his veins 2020 MOP shirt diet and habitat. Greenland sharks live at such extreme depths and at such extreme temperatures that they kinda have to look a bit funky to survive. Animals don’t care if they look weird – if their bauplan works, then it works. Greenland sharks are benthic feeders, adapted for slowly patrolling and hovering over the seabed. A short, broad tail with a longer upper caudal is helpful for cruising just over the bottom. As mentioned, they get most of their food from the bottom of the seabed. As a result, their mouths are positioned more on the bottom of their heads, rather than facing forwards like, say, a great white – this makes it easier for them to slurp up whatever food is resting on the benthos.
