11. There is also interspecies variation, especially ontogenetic changes as a fish experiences growth. 12. Its duller colouration suggests that the species undergoes an ontogenetic colour shift at maturation. 13. His argues that all ontogenetic events are the mechanical result of differential cell growth. 14. During their ontogenetic development, in juveniles at first the ribs fused with their vertebrae. 15. Hyperolius ocellatus is an ontogenetic frog with dramatic differences in both color and pattern between the sexes. 16. The ontogenetic development of social cognition may be thought of as intertwined with the development pointing actions. 17. Footballfish are presumed to be non-guarders that ontogenetic descent into deeper waters as the larvae mature. 18. Lev Tsenkovsky was one of the pioneers of the ontogenetic method of studying lower plants and lower animals. 19. The same conclusion has been made based on the ontogenetic , biostratigraphic, and paleobiogeographic data and interpretations. 20. Due to their different ontogenetic origins, the epithalamus and the perithalamus are formally distinguished from the thalamus proper.
