Catadromous eels continue to be slippery research subjects
As adults, Atlantic eels ( Anguilla rostrata in the Americas and Anguilla anguilla in Europe) are tubular slime‐covered fish that spend most of their catadromous life cycle in coastal environs before swimming far out to sea to reproduce, as part of an intergenerational migratory circuit that provide...
