Note the healthy-looking appearance of this juvenile, the two parts of the inflated swim bladder, the almost completely degenerated eye, and the digestive system filled with food. Scale bar as in B. B Body, with the digestive system exposed C Stomach and intestine. Notice that the food content can be seen through the translucent walls. All fish studied were well fed and their guts were full of food.

Figure 4 - Gut contents of Pachón cave fry. A–C Cladocera Water fleas. This species constituted by number the most encountered prey. On average, fry had in their guts 9.3 individuals of this species D Harpacticoida copepod. Arrow highlights the short antennae diagnostic of class Harpacticoida. This species constituted by number the second most encountered prey. On average, fry had in their guts 4.7 individuals of this species E–F Copepods. Arrow highlights the long antennae diagnostic of non-harpacticoida copepods G Ostracod. This and possibly two more species of ostracods were in their guts H Isopod. While only one specimen was eaten, due to its large size it constitutes a large stomach content by volume I Sclerites of arthropods, possibly of insects. Contrary to all of the above, they have pigment, suggesting that some may be surface insects. Some may be a by-product of eating guano from insectivorous bats.

Data from: Utility of geometric morphometrics for inferring feeding habit from mouthpart morphology in insects: tests with larval Carabidae (Insecta: Coleoptera)
Feeding habits are important life-history traits in animals; however, methods for their determination are not well established in many species. The larvae of the beetle family Carabidae are an example. The present study tested the utility of geometric morphometrics of mouthpart morphology to infer the feeding habits of carabid larvae. Using Pterostichus thunbergi as a model system, larval feeding habits were inferred using geometric morphometrics of mouthparts and the results were compared with those obtained from rearing experiments. The rearing experiments indicated that P. thunbergi larvae are carnivores that require snails as an essential part of the diet. Through geometric morphometrics, associations between mouthpart morphology and larval feeding habits were confirmed for species in which these two traits are known. A discriminant analysis using these associations classified P. thunbergi larvae as snail/slug feeders, which is a result compatible with the rearing experiments. Geometric morphometrics also revealed that morphological integration and ontogenetic shape change might play roles in the diversification of mouthpart morphology. Overall, these results demonstrate the utility of the geometric morphometrics of mouthparts to infer feeding habit and to clarify the mechanisms of mouthpart morphological diversification in the study group, and the results also serve as a basis for future studies of other insect groups.
