Blackfin sorcerer eels live in the coastal waters of the Atlantic Ocean and also in the western Mediterranean Sea.

They are more concentrated in the waters surrounding the Caribbean, the Azores, the Canary Islands and the northern Mediterranean Sea.

They are similar in appearance to other members of the family Nettastomatidae, with the trademark duck-bill-shaped mouth.

The mouth is black in color and is considered large relative to the body size.

The blackfin sorcerer is known to live in holes on the bottoms of continental slopes.
