Search of gut-related bibliography was conducted, using online literature databases on fish feeding and ecomorphology. The relations between gut length (GL) and body length (L) provided by the original authors, regressions were reconstructed and compared based on species' feeding habits and taxonomy. The amount of information related to gut morphometrics referred to 498 species. The relations between GL and L referred to 71 species, but four species were omitted from the analyses. The GL_L regressions performed for 67 species revealed the presence of two major groups as herbivorous fishes and carnivorous fishes. All the analyses performed on the compiled data reinforced the pattern generally accepted that herbivores have longer intestines than carnivores. Existing information on intestine morphometrics is generally accumulated in a few scientific papers
