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.

Icewind
Icewind eels were a species endemic to the Sea of Moving Ice. They were a commonly served dish within taverns across the coast of Icewind Dale, often served battered and fried.

Lamprey
Lampreys were a species of leech-like eels.

Mkunga
Mkungas were a large species of eel endemic to the inland rivers of the Chultan Peninsula. They typically migrated downstream to the Trackless Sea to give birth in shallow, brackish inlets. Most would return upstream until they matured, though some would spend their whole lives within those estuary waters.

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.

Splar
Splars were a species of eel with wing-like fins that allowed them to leap from out of the water.

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

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.

Wolf
Wolf eels, otherwise known as akoak by Ice Hunters, were a rare species endemic to the Sea of Fallen Stars. Their bodies were blue and had large crushing jaws capable of eating sea barbs, woolly crabs and oysters. Ice Hunters that swam alongside them during exceptionally warm summers noted that they were generally non-threatening and curious creatures.
