New Zealand Longfin Eel (Anguilla dieffenbachii)

The New Zealand Longfin Eel or Anguilla dieffenbachii is a freshwater fish that can be distinguished from other Eels by the length of its fins. The dorsal fin of the New Zealand Longfin Eel extends further towards the head then the anal fin. This is in contrast to the Shortfin Eel which fins are both of similar lengths.     

Like some species of Trout, this fish will spend their lives in freshwater, but migrate to saltwater to breed. Longfin Eels are from the Anguillidae family and are quite large measuring in at up to 53lbs (24kg). This impressive size doesn't happen overnight though, in fact they are the slowest growing of all Eel species. They are also one of the longest lived, managing to make it to the ripe old age of 106! 

New Zealand Longfin Eels are omnivores that are not considered to be picky eaters. They will chow on insect larvae of all kinds and small fish as well. Some folks even think they might attack a human under the right circumstances. Have a look at this video from River Monsters that shows their powerful appetites.

These eels have poisonous blood and are not edible.
