Details

Habitat

Occurs on continental shelves and slopes of the eastern Atlantic and Mediterranean, on sand, mud, gravel, and deeper coastal bottoms.

Appearance

The head is broad and flattened, while the body narrows behind it. A modified dorsal fin ray forms a fishing-rod-like lure above the mouth.

Behavior

It lies camouflaged on the seafloor and flicks the lure to attract prey. Its strategy is ambush rather than active pursuit.

Feeding

It swallows fishes, squid, and crustaceans, using sudden suction and a large mouth to capture animals that come close.

Reproduction

Females release long gelatinous ribbons of eggs into the sea. Young fish gradually take on the adult bottom-dwelling form.

Notes

The tail is valued as seafood. Because it is taken in bottom fisheries, regional stock management is important.
