Sharks are often spoken of with fear and awe, but they are just animals in the water. They are complex creatures that do more than just swim around to kill, and people tend to be wary of great white sharks. In this article, we’ll take a closer look at the diets of other large shark species. What Greenland Sharks Do Indeed there is? And what about people on their menu?
These “sleeping sharks” are the longest living vertebrates in the world and have been confirmed to live for over 400 years. Let’s hope it doesn’t go away as it is currently listed as “endangered” by the International Union for Conservation of Nature (IUCN).
Their short snouts and small eyes, fins and gill holes seem deceiving compared to their sheer size. Mostly gray or black-brown, they are secretive predators, and if not for their mass, they could blend in with their environment.
Let’s focus on what the arctic water lover eats.
What do Greenland sharks eat?
You’ve probably seen a “sucker fish” at the edge of a small aquarium that sucks in algae and other debris. Greenland sharks in the North Atlantic Ocean have something in common with them … They will eat almost any flesh, living or dead, in the ocean. They are not picky.
Having said that, you can relax. They make No chase or eat people. At least the cases have not been confirmed. Although they are predators, they are not aggressive. Primarily scavengers, Greenland sharks mainly eat:
- A fish
- And others (as they are scavengers)
- Squid
- Seals
- Other sharks
- Acne
- Seabirds
- Parts of horses, reindeer, moose and polar bears have even been found in their digestive systems.
Greenland sharks often overeat when they find food, as they can go without food for a long time. It is the slowest fish, at 0.76 mph, and has an extremely low metabolism, which is likely due to its ability to traverse longer periods of time without eating.
They are attracted by the smell of rotting meat, as well as the smell of live prey. As marine “garbage eaters”, their meat is full of pollutants and toxic to human consumption, but in Iceland they are treated and eaten as a delicacy.
Greenland shark predators
Although they are fairly safe among other creatures, killer whales and sperm whales are believed to feed on Greenland sharks as their liver contains a significant amount of fat.
How do Greenland sharks eat
When Greenland sharks do attack, their jaws make a rolling motion. Their upper teeth are thin and not serrated, but act as a tool to squeeze the prey. The lower teeth are square and point in opposite directions, making it easier to collect entrapped food.
Because their movements are painstakingly slow, although capable of short bursts of speed, at around 1.6 miles per hour, bowhead sharks often eat sleeping prey. They have a large buccal cavity into which fish is absorbed, and this is probably why they were found intact in their systems.
Eaters of opportunity, they’ve been spotted near fishing boats to eat. Greenland sharks need to get what they need in their diet as they can grow up to 20 feet in length and up to 2,200 pounds! One thing’s for sure: this species doesn’t have calorie counting.
