| Other Names | Seawolf, Ocean Catfish, Devil Fish |
| Conservation Status | Near Threatened (IUCN Red List) |
📍 Habitat & Distribution
Geographic Range: North Atlantic Ocean
Found off the coasts of North America (from Labrador to Cape Cod)
Present in European waters, especially around Iceland, Norway, Barents Sea, and British Isles
Habitat:
Cold, deep-sea environments
Lives near the bottom (demersal species) at depths of 20–500 meters
Prefers rocky or muddy seafloors, often hides in crevices
🧬 Physical Characteristics
| Feature | Description |
|---|---|
| Size | Up to 1.5 meters (5 ft); 18–40 kg (40–88 lbs) |
| Body | Elongated, eel-like, powerful body |
| Teeth | Large, canine-like front teeth, molar-like back teeth |
| Color | Bluish-gray to olive green; sometimes mottled |
| Fins | Long dorsal fin from head to tail |
Teeth are adapted for crushing hard-shelled prey like sea urchins and crabs.
Not dangerous to humans unless handled carelessly (strong bite).
🍽️ Diet
Carnivorous; specialized in crushing prey with hard shells:
Sea urchins
Crabs
Lobsters
Mollusks (clams, snails)
Starfish
They help control populations of these invertebrates, playing a key role in benthic ecosystems.
🐣 Reproduction
Spawns in late fall to early winter
One of the few fish where males guard the eggs after fertilization
Eggs are large and laid in clusters on the sea floor
Slow-growing, late to mature — making them vulnerable to overfishing
⚠️ Conservation & Threats
| Threats | Details |
|---|---|
| Bycatch | Often caught unintentionally in trawl and gillnet fisheries |
| Habitat destruction | Bottom trawling damages seafloor habitats |
| Climate change | Rising temperatures affect cold-water species |
| Slow reproduction rate | Reduces population recovery ability |
🔴 Status: Near Threatened
Efforts are underway in some regions to limit bycatch and protect habitats.
🍽️ Culinary & Commercial Use
Edible and occasionally sold as sea catfish or ocean whitefish
Mild flavor, firm white flesh
Not a major commercial fish, but caught in small-scale fisheries
Note: In some cultures, it is considered a delicacy, particularly in Scandinavia and Newfoundland.
🔬 Fun Facts
Produces antifreeze proteins in its blood to survive frigid waters
Looks fearsome but is generally non-aggressive
Their powerful jaws can crack open even the hardest sea urchin shells
Sometimes kept in public aquariums due to their unique appearance
📸 Appearance (Visual Description)
A broad, flattened head with bulging eyes and prominent teeth
Long body with a single continuous dorsal fin
Mottled or solid coloration depending on age and habitat
