without an amnion
Etymology
'anamniotic' originates from Greek, specifically the prefix 'an-' meaning 'without' and 'amnion' meaning 'membrane around the fetus.'
'anamniotic' was formed in modern scientific English by combining the Greek elements 'an-' and 'amnion' with the suffix '-ic' to describe animals lacking an amnion.
Initially, it meant 'without an amnion,' and this meaning has remained consistent in scientific usage.
