'amphidiscophora' originates from Greek, specifically the words 'amphi-' meaning 'both' and 'discus' meaning 'disk', referring to the disk-like structures in their skeletons.

'amphidiscophora' was derived from the Greek terms 'amphi-' and 'discus', and was adopted into scientific Latin to describe this subclass of sponges.

Initially, it referred to the disk-like structures in the skeletons of these sponges, and this meaning has remained consistent in modern usage.
