Normal resting heart rate. It is important to identify whether your heart rate sits within the normal range. If disease or injury weakens the heart, the organs will not receive enough blood to function normally. The United States National Institutes of Health (NIH) have published a list of normal resting heart rates.
There are currently two recognized species of wolves, the Canis lupus, or grey wolf, and the Canis rufus, or red wolf. These are two of the species that comprise the Canidae family in the Carnivora order. The red wolfâs Genus name, Canis, is Latin for dog.
The wolf is an ancestor of the domestic dog but instead of barking, it howls. The grey wolf has a number of subspecies, including the Arctic wolf, which vary in colour and size according to where they live. The grey wolf has strong jaws with sharp canine and carnassial (cheek) teeth for tearing and chewing meat. Size. Length: 120-200cm.
