In biology, relating to having two bodies or existing in two distinct physical forms.
From dis- (two) + somatic (relating to the body), from Greek soma 'body.' The term combines the prefix meaning 'two' with somatic to describe organisms or conditions with two-body characteristics.
This term appears in parasitology and developmental biology to describe organisms or life stages that have two distinct bodily forms—some parasitic worms do this! It's the kind of highly specialized vocabulary that exists in niche scientific fields where precision about unusual biological phenomena matters.
