Eel

Eels were aquatic creatures.

Dreel
Dreel eels, sometimes known as trollfingers due to their appearance, were a species of river eel found in the River Reaching in the Western Heartlands. Their bodies were short, yet fat, and green-black in color. They subsisted upon algae and carrion, which kept the river's waters both clean and clear. They had a taste reminiscent of mucus, but could be quite nourishing, thus they were often fried with certain herbs or spices to mask their natural taste.

Electric
Electric eels were a rarely-sighted species in Faerûn that possessed the unique ability to discharge a field of electricity.

Lamprey
Lampreys were a species of leech-like eels.

Vilhon
Vilhon eels were a species endemic to the Vilhon Reach. They had long and ribbon-like bodies, black in color with green mottling. They often proved difficult to catch by fishermen using nets. They were a local delicacy in Nimpeth.

Suckertails
Suckertails were a variety of eels from Laerakond, highly appreciated by the people of Tarmalune due to their eating habits.

Onsler
Onsler eels were a species of freshwater eel that inhabited shallow streams and deep rivers throughout the Heartlands. They had pale skin, marked with dusty-white spots, and soft sucker mouths. They were sensitive to extreme temperatures and would die if water got either too cold or too hot. They were a rather passive and herbivorous species, subsisting on algae as well as aquatic mosses and lichen. They were capable of living longer than the average human; their bodies grew longer and broader as they aged, with young specimens being more cylindrical and older ones being more flatter. Their flesh had a pleasant texture, but was rather tasteless, thus they were typically doused in sauce or heavily seasoned.

Monstrous eels
Ghartii Nung was an enormous 100-feet-long (30 meters) eel that once dwelt in the Yellow Sea off the coast of Koryo in Kara-Tur, until it was caught by local fishermen.
