There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water.
In animal studies, maximum span is often taken to be the mean life span of the most long-lived 10% of a given cohort. By another definition, however, maximum life span corresponds to the age at which the oldest known member of a species or experimental group has died. Calculation of the maximum life span in the latter sense depends upon the ...
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 New Zealand longfin eel is a very long-lived fish, with records of females reaching 106 years old and weighing up to 24 kg. [5] [9] They have the slowest growth rate of any eel species studied, just 1–2 centimetres a year. [10] Longfin eel seen in a river at night in the Tararua Ranges
