The fish with the ugly appearance

The Atlantic wolffish has a formidable appearance. It has a large head, a large jaw and a powerful set of teeth. Even when the Atlantic wolffish's mouth is closed, its front teeth protrude.

Hard diet

The Atlantic wolffish eats sea urchins, mussels and crabs, which it catches with its razor-sharp front teeth. It easily crushes its shelled prey between its powerful jaws. The hard diet causes wear and tear to the Atlantic wolffish's teeth. But this is not a problem, because every winter it develops a new set of teeth.

Warm blood

The Atlantic wolffish has a kind of natural antifreeze in its blood. So its blood never freezes, not even when the water is at freezing point.

World's biggest fish egg

The Atlantic wolffish's egg is up to 6 mm in diameter. These are some of the largest fish eggs in the world. During autumn, the female spawns eggs and guards them for 2 months until they hatch.

Packed lunch

After the young fish hatches from the egg, it obtains nourishment from the yolk sac for the next 3-4 months. It spends all of its time on the seabed. Only when the yolk sac has been consumed does the young Atlantic wolffish begin to swim around in the water.

Is the Atlantic wolffish dangerous?

If a fisherman catches an Atlantic wolffish, he must be careful to not get bitten, but the wolffish is not dangerous. In the old days, fishermen told stories of how an Atlantic wolffish could attack a boat's oars and continue biting even when its teeth were broken. But these stories are not true.
