'amphiumidae' originates from Greek, specifically the word 'amphi,' meaning 'both' or 'double,' and 'ium,' a diminutive suffix.

'amphi' combined with 'ium' to form the genus name 'Amphiuma,' which eventually led to the family name 'amphiumidae.'

Initially, it referred to the dual nature of the limbs, and this meaning has remained consistent in modern taxonomy.
