Shape analysis of the jaws between two minnow species over ontogeny

Abstract: This study compares sand shiner (Notropis stramineus) and silverjaw (Ericymba buccata) minnows, in terms of the morphological shape changes of the upper, lower, and pharyngeal jaws over ontogeny. These two species of minnows initially feed on midge larvae and undergo an ontogenic prey shift. The traditional morphometrics measured-total length, snout-to-vent length, eye diameter, premaxilla length, lower jaw length, gape-were regressed onto total length to test for allometry. Digital pictures were processed wit… Show more

“…Morphometric image analyses quantify the size dimensions and geometric shapes of structures from digital photographs. Such analyses can measure the whole body plans of biological specimens, 2 specific body parts (e.g., jaws 3 ), and anatomic features on bones, 4 scales, 5 beaks, 6 shells, 7 wing venation, 8 eggs, 9 seeds, 10 on scans of brain regions 11 and pharyngeal airways. 12 Morphometric image analyses are also used to analyze fossils 13 and archaeological artefacts such as arrow points.…”
