Abstract
This study aims to investigate the anatomy of coronary arteries and their primary branches in neotropical carnivores, given the functional significance of coronary circulation and the limited existing descriptions in this order. For this purpose, coronary arteries were dissected, and their branches were counted in 74 hearts from 20 species belonging to five families: Canidae, Mustelidae, Procyonidae, Mephitidae, and Felidae. In all specimens of the suborder Caniformia, the subsinuosal interventricular branch originated at the end of the circumflex branch of the left coronary artery (LCA). In contrast, in all hearts of Felidae specimens, the subsinuosal branch was derived from the right coronary artery. Among the 50 neotropical specimens of the suborder Caniformia, 13.1 ± 5.2 ventricular branches originated from the LCA and only 4.6 ± 1.4 from the right (p < 0.0001), characterizing a consistent left dominance. However, in the 24 specimens of the Felidae family, 10.5 ± 4.0 ventricular branches were found originating from the LCA and 10.4 ± 3.4 from the right, with no difference between the means (p = 0.82), defining a balanced pattern. It is suggested that the type of coronary circulation may correlate with the phylogeny of carnivorans.

Abstract
In 2016, two adult male sperm whales beached off of Yangkou Port in Nantong City, Jiangsu Province, China. The local government planned to preserve them as specimens, one was entrusted to Dalian Hoffen Biological Co., Ltd., and thus became the first sperm whale to be preserved by plastination. The other sperm whale was preserved in Nantong by the traditional stripping method (The skin was preserved, and then the prosthesis was filled into the skin to preserve the specimens. The material of the prosthesis was polyurethane. The outline of the animal was sculpted by suturing the skin like a bag and filling it with polyurethane). Plastination of such a large marine mammal allowed us to view the mutual adaptations of its internal structure to its specific living environment and daily habits. This sperm whale is the largest specimen in the world and this is the first time a sperm whale has been preserved using the plastination method. The plastination process also provides a method for studying the anatomy of large marine mammals for humans to understand deep-sea organisms at close contact and visual level. The plastination of this sperm whale promises to be a world class resource holding tremendous scientific, educational, and artistic value.

Abstract
In contrast to studies on domestic animals, few reports describe ventricular bands in wildlife, and none in aquatic mammals. Ventricular bands in the endangered Saimaa ringed seal (Pusa hispida saimensis) and the Baltic ringed seal (Pusa hispida botnica) were examined as part of an ongoing research on the comparative anatomy of ringed seal subspecies. The dissections illustrated that a varying number of thin or thick ventricular bands from the papillary muscles to the ventricular walls were visible in the ventricles of all ringed seal specimens examined. The histological appearance of the ventricular bands was characterized by a fibromuscular pattern.

Abstract
AbstractThe aim of this study was to investigate the morphology of the coronary arteries of the goat’s heart. The study was carried out on 36 hearts of adult females dairy goats, belonging to two breeds, aged 7–12 years, with an average body weight of 37 kg. A distinct view of coronary arteries and their branches was obtained by filling them with dyed synthetic latex (LBS 3060) or Batson’s No. 17. In all studied goats the common trunk of the left coronary artery was divided into the interventricular paraconal branch and the circumflex branch. The branch of the interventricular septum originated in the interventricular paraconal branch. In 25 individuals (69%) the circumflex branch ended with small ramifications on the atrial surface of the heart. In 11 individuals (31%), the vessel extended in the subsinuosal interventricular groove into the subsinuosal interventricular branch. The right coronary artery was less developed than the left coronary artery. In 35 individuals (97%) the right coronary artery ended with small ramifications on the atrial surface of the heart. In one goat (3%) the vessel reached the subsinuosal interventricular groove and extended into the subsinuosal interventricular branch.

Abstract
The aim of this study was to measure the area of the coronary ostia, assess their localization in the coronary sinuses and to determine the morphology of the stem of the left and right coronary arteries in the domestic shorthair cat. The study was conducted on 100 hearts of domestic shorthair cats of both sexes, aged 2-18 years, with an average body weight of 4.05 kg. A morphometric analysis of the coronary ostia was carried out on 52 hearts. The remaining 48 hearts were injected with a casting material in order to carry out a morphological assessment of the left and right coronary arteries. In all the studied animals, the surface of the left coronary artery ostium was larger than the surface of the right coronary artery ostium. There were four types of the left main coronary artery: type I (23 animals, 49%)-double-branched left main stem (giving off the left circumflex branch and the interventricular paraconal branch, which in turn gave off the septal branch), type II (12 animals, 26%)-double-branched left main stem (giving off the left circumflex branch and the interventricular paraconal branch without the septal branch), type III (11 animals, 23%)-triple-branched left main stem (giving off the left circumflex branch, interventricular branch and the septal branch, type IV (1 animal, 2%)-double-branched left main stem (giving off the interventricular paraconal branch and the left circumflex branch, which in turn gave off the septal branch). The left coronary artery ostium is greater than the right one. There is considerable diversity in the branches of proximal segment of the left coronary artery, while the right coronary artery is more conservative. These results can be useful in defining the optimal strategies in the endovascular procedures involving the coronary arteries or the aortic valve in the domestic shorthair cat.

Abstract
Background The European bison (Bison bonasus) is an endangered species. More information on its anatomy is needed as only few studies have been published. This study is the first report on the morphology of the coronary vessels. Given the anatomical similarity between the European bison and other ruminants, the results of this study can be applied to other species, including endangered ones. Results The study was conducted on 70 hearts of European bisons of both sexes, aged 5–20 years, with an average body weight of 449 kg. A distinct view of subepicardial arterial vessels was obtained by filling them with dyed synthetic latex (LBS 3060) and Plastogen G. There was a division of the common trunk of the left coronary artery into the interventricular paraconal branch and the left circumflex branch in 63 individuals (90 %). In five individuals (7.1 %), the presence of a third vessel, which was a branch of the interventricular septum, was observed. There was a lack of a common trunk in two individuals (2.9 %). Ramifications of the interventricular paraconal branch to the wall of the left ventricle were significantly larger than those to the wall of the right ventricle. In 17 individuals (24.3 %), the right coronary artery extended into the subsinuosal interventricular branch. Conclusion The blood supply to the heart in bisons is provided by the left and right coronary arteries. In all the studied specimens, the left coronary artery was better developed than the right coronary artery.
