Having the shape or appearance of a cockroach, particularly the flattened dorsal-ventral body form.
From Latin blatta (cockroach) combined with -form (form, shape), a productive suffix in scientific nomenclature. This descriptive term emerged as scientists needed precise anatomical vocabulary.
Many insects that aren't cockroaches are called blattiform because they've evolved the same body shape—this is convergent evolution, where different insects independently discover the same winning design.
