Morphological Description of Digestive Tract in Golden Jackal (Canis Aureus Moreoticus)
Open accessAbstract
The Golden Jackal is continuously spreading throughout central and Eastern Europe.In Romania the living area of this specie is in Dobrogea and Danube Delta, South-Eastern Moldova, South Muntenia and Oltenia, West Plains and some areas in Central Transylvania Plateau.Surprisingly, despite its fast spreading during the last years, this species has not been of great interests for researchers.Therefore, a proper understanding of the anatomy of this species is required.Using gross dissection of four subjects, this study achieves a detailed description of anatomical particularities of the digestive tract in Golden Jackal.Given the carnivorous diet, the digestive tract anatomy of Golden Jackal is adapted to this type of nutrition.The type of dentition is dyfyodont with strong and conical crown of incisors and canines.The stomach (Gaster) is elongated without an obvious duodenal ampulla (Ampula duodeni).The descending duodenum ansa is not covered by omentum (Omentum majus).The jejunum (Jejunum) and ileon (Ileum) are long with well represented corresponding mesentery (Mesenterium).The cecum (Caecum) is small but obvious; the colon has no sacculations and low distinguishable sections, showing only a sigmoid expansion.Para-anal glands are well developed.

The gastrointestinal tract of L. culpaeus is very similar in form and shape to the golden jackal, Canis aureus, suggesting that canids lack pronounced mucosal folds typical in other species such as E. barbara and N. felipei.
“However, the gastrointestinal tract reported herein is very similar in form and shape to the golden jackal, Canis aureus Linnaeus, 1758, suggesting that the canids lack pronounced mucosal folds typical in other species as the E. barbara and N. felipei (Stan 2016;Lima et al. 2018;Ramírez-Chaves et al. 2024).”

The anatomical description and Conclusion (page not supplied) document the golden jackal’s digestive tract and say its overall morphology resembles that of the domestic dog. They do not compare it with L. culpaeus or discuss mucosal folds in canids, E. barbara, or N. felipei; the reported absence of colonic muscular bands or haustra does not establish an absence of mucosal folds. (LLM, conf=0.86)
Experimental — accuracy not yet measuredInformation on canine gastrointestinal anatomy is scarce.
“Information on canine gastrointestinal anatomy is scarce (Mech 1974;McGrosky et al. 2016;Stan 2016;Boyd 2022)”
From The Andean fox Lycalopex culpaeus (Molina, 1782) in southwestern Colombia: diet and anatomical description (2026) · cites this paper as Stan 2016
The Abstract (page unavailable) says golden jackals have attracted little research interest and calls for a better understanding of their anatomy. That lends support to a scarcity of information about golden jackal anatomy, but it does not establish that information on canine gastrointestinal anatomy generally is scarce. (LLM, conf=0.82)
Experimental — accuracy not yet measuredThe stomach of C. aureus presents a deeper angular notch compared to the cardiac notch, while L. culpaeus has a similar depth in both, which can allow L. culpaeus to store more food than the golden jackal.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
