'aistopod' originates from Greek, specifically the word 'aistos,' meaning 'unseen,' and 'pous,' meaning 'foot.'

'aistos' and 'pous' combined to form the term 'aistopod,' referring to the limbless nature of these creatures.

Initially, it referred to the unseen or hidden nature of the limbs, but over time it became a term for the entire group of these extinct amphibians.
