New Zealand short and long fin eels are also quite interesting. They live in rivers and go far inland, able to climb even 20m waterfalls, but breed only once right at the end of their life cycle somewhere in the sub-tropic Pacific, probably in deep trenches, but it is not known where. The longfin eels are 2m in length, can weight up to 25kg and live 40-70 years. https://www.doc.govt.nz/nature/native-animals/freshwater-fish/eels https://www.doc.govt.nz/nature/native-animals/freshwater-fis... https://www.rnz.co.nz/national/programmes/ourchangingworld/audio/2018695044/mystery-of-the-longfin-eel-s-breeding-ground https://www.rnz.co.nz/national/programmes/ourchangingworld/a...
