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.
There are three species of wolves in the world-the grey wolf (Canis lupus), the red wolf (Canis rufus) and the Ethiopian wolf ((also known as Abyssian wolf, Ethipioan JAckle â¦ , and Simain fox))(Canis simensis).    The grey wolf, of which there are numerous subspecies, is found across North America and Eurasia.
