With its powerful teeth and sharp eyes, it looks like a tiger or wolf of the jungle. Its dark skin and menacing face, lurking in the dark, inspire fear. Yet it is not a land animal but a mysterious and rare creature that lives in the depths of the sea. Its name is the wolffish, and its strange appearance and predatory nature make it one of nature's wonders.
Its scientific name is Anarhichas lupus, and it is commonly known as the Atlantic wolffish. It is a deep-sea fish found in the cold waters of the North Atlantic Ocean. Its strong build and dangerous teeth make it look rather like a wolf or a lion, which is why it is called the wolffish.
Body and habitat
The wolffish has a particularly powerful body and very sharp teeth, which it uses to crunch hard-shelled molluscs and crustaceans. The fish can grow to about 1.5 metres, though it is usually 90-100 cm long. Its skin is smooth and bare, unlike that of many other fish.
It generally lives in the cold, deep waters of the North Atlantic, especially off the coasts of Canada, Iceland, Greenland and Norway. It usually stays at depths of 200 to 800 metres, though it sometimes goes deeper towards the sea floor.
The wolffish mainly eats fish, shelled molluscs and crustaceans. Its strong teeth and jaws help it chew shelled animals easily. Its diet is made up mostly of shellfish, crabs and small fish.
Conservation
Although wolffish numbers are not yet at a dangerous level, overfishing and the loss of natural habitat could put the species at risk. Various marine organisations and researchers are working to conserve the fish and stress protecting ocean biodiversity to keep it safe.
The wolffish is a particularly fascinating animal of the sea. Its build, diet and habitat mark it out as an important member of the ocean. Our interest in and attention to this mysterious creature of the deep need to be kept up so that its conservation can be ensured.
