== Taxonomy == left|thumb|C. nepaholica specimen, Denver Museum of Nature and Science Cimolichthys was a large-sized nektonic aulopiform fish, making it related to modern lancetfish and lizardfish. Within the Aulopiformes, it is generally considered a member of the Enchodontoidei, a dominant group of predatory nektonic fish throughout much of the Cretaceous; however, some other treatments instead place it outside the Enchodontoidei and in a basal position as sister to the waryfishes, a small family of extant deep-sea aulopiformes. Yet other studies have instead placed it as a sister to the extant daggertooths.
