Although Schmidt did not directly observe eel spawning, or even find ready-to-spawn adult eels, he deduced the following about the life history of the eel, based on the size distribution of the leptocephali he collected: The larvae of European eels travel with the Gulf Stream across the Atlantic Ocean from the Sargasso Sea, and grow to 75–90 ...

However, these eels do not necessarily reproduce every year-they will sometimes wait until conditions are right in order to migrate and breed. The European eel can spawn starting at 7 years old, and the oldest of this species that has been found in the wild was 85 years of age. [22]
The adults spawn in nests of sand, gravel and pebbles in clear streams. After hatching from the eggs, young larvae—called ammocoetes [ 49 ] [ 50 ] —will drift downstream with the current till they reach soft and fine sediment in silt beds, where they will burrow in silt, mud and detritus, taking up an existence as filter feeders, collecting ...
The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus Electrophorus), swamp eels (order Synbranchiformes), and deep-sea spiny eels (family Notacanthidae). However, these other clades , with the exception of deep-sea spiny eels, whose order Notacanthiformes is the sister clade to true eels, evolved their eel ...
The New Zealand longfin eel (Anguilla dieffenbachii) is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel (Anguilla australis), also found in Australia, and the naturally introduced Australian longfin eel (Anguilla reinhardtii).
The silver lamprey is an eel-like fish with an attenuate body composed of 49–52 clearly defined segments (i.e. myomeres, between the last gill slit and the anus).Silver lampreys possess a cartilaginous skeleton, and adults generally grow to a length of 12 inches and are silvery or bluish in color when spawning.
Based on collections of their small leptocephalus larvae, the American conger eel has been found to spawn in the southwestern Sargasso Sea, close to the spawning areas of the Atlantic freshwater eels. "Conger" or "conger eel" is sometimes included in the common names of species of the family Congridae, including members of this genus.
