Do Oarfish Eat Other Fishes?

Oarfish don’t eat other marine fishes as food. Although they’ve big bodies, they still depend on small planktons, tiny marine creatures, shrimps, krills, and squids.

Big fishes or regular sea fishes are not the prey of Oarfish. As Oarfish live in solidarity without family members, they’re believed to be living alongside other fishes.

There is no exact information about this fact on the net. However, as you already know, Oarfish are carnivorous and live on eating small fishes, plankton, and shrimps; it’s believed that they don’t eat their babies or themselves.

Does Oarfish Eat Humans?

Oarfish are carnivorous, and they don’t eat humans or cause any harm to them. This is also the case for giant Oarfish too! Although it’s quite common to assume giant Oarfish as dangerous, in reality, they’re not!

I agree that Oarfish look dangerous due to their mammoth body size and shape. But it’s found that they are quite friendly towards humans and have no tendency to cause any harm, eat or kill humans for food.

There are 3 main reasons I identified why Oarfish could not eat humans or cause any harm to them. Here are the reasons-

  • Oarfish seldom come to the surface of their water. So there’s almost no chance of getting harmed by Oarfish.
  • As you already know, Oarfish have no real or visible teeth. They take their food through suction by a duct called a gill raker. So that’s why Oarfish cannot bite you and have lesser chances of being attacked by them.
  • Besides, Oarfish swim vertically by keeping their head in the downward position. This helps them to scan for krills and food easily.

You can understand why they cannot harm you as they swim by keeping their head in the downward direction.

Even the Oarfish that was caught live on the shores had no intention of causing harm to humans. Even though they’re called sea monsters or sea serpents, they’re friendly and not dangerous at all!

There are hardly any Oarfish in aquariums all around the globe. The reason being most Oarfish found on the shore were mostly dead. However, one giant Oarfish was reportedly kept in an aquarium in Japan.

Oarfish don’t survive in aquariums or captivity. They must be kept in deep water bodies, and the water pressure needs to be regulated properly. And on top of that, they need salt water.

As the one kept in the aquarium did survive for a few hours, it was impossible to know about its food habit or diet in aquariums.
