It is wild to me that
1. nearly every commercial species of eel is endangered,
2. no one has ever successfully bred an eel in captivity\* and
3. eel is available in basically every sushi place in America (it's actually hard to avoid!
See https://en.wikipedia.org/wiki/Eel#Commercial_species
\*Some scientists managed to get some new eels hatched, but they died after 18 days. Not exactly a good foundation for aquaculture.
