The main artery splits into the left pulmonary artery and the right pulmonary artery, each of which directs the blood to the corresponding lung. Along with the umbilical arteries, these are the sole arteries in the body that transport oxygen-depleted blood. The umbilical arteries are located in the uterus.
The dire wolf averaged about 1.5 m (4.9 ft) in length and weighed between 50 and 79 kg (110 and 174 lb), which made it the largest species in the genus Canis. Limb elements are rarely found outside the La Brea Tar Pits, which makes it hard to compare the size of average individuals between populations.
It is a huge and very powerful beast. The liger is a hybrid cross between a male lion (Panthera leo) and a female tiger (Panthera tigris). Thus, the liger has parents of the same genus but of different species. The liger is distinct from the similar hybrid tigon.While the Siberian tiger is the largest pure sub-species, ligers are believed to be the largest of all known extant felines. Ligers exist only in captivity or zoos because the habitats of the parental species do not overlap in the wild.ther big cat hybrids can reach similar sizes; the litigon, a rare hybrid of a male lion and a female tigon, is roughly the same size as the liger, with a male named Cubanacan (at the Alipore Zoo in India) reaching 363 kg (800 lb).
