[23] [24] As open ocean voyagers, eels need the carrying capacity of the swimbladder (which makes up 3–6% of the eel's body weight) to cross the ocean on stored energy alone. Because the eels are catadromous (living in fresh water but spawning in the sea), dams and other river obstructions can block their ability to reach inland feeding grounds.
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 young eel larvae live only in the ocean and consume small particles called marine snow. Anguillid eels lay adhesive demersal eggs (eggs that are free-floating or attached to substrate), and most species have no parental care. [29] Japanese eels (A. japonica) can lay between 2 million and 10 million eggs. [22]

The young eels are born in marine water, and then migrate into freshwater to live out most of its life. When the time comes to reproduce, the adult eels migrate back into the ocean to breed. Recently hatched eels, or elvers, are not seen in freshwater, and there is only one record of a G. polyuranodon elver found within
After being swallowed alive, Japanese eels were able to escape from a predator fish’s stomach and swim to freedom through the fish’s gills, new research shows.
