Depending on the breed, foxes can run at speeds between 30 and 40 miles per hour. For instance, the typical red fox can run at a top speed of about 48 kilometres per hour, or about 30 miles per hour. Another illustration is the grey fox, which can run at a top speed of about 42 mph.
The University of Michigan claims that the red fox can jump over two-meter-high barriers in addition to running at a speed of 30 miles per hour. For strong traction on the ground, they have claws on both their front and back feet. They have four claws on their back foot and five on their front feet.
Foxes must be able to run quickly in order to obtain prey and evade bigger predators. When they are being pursued, they can also use impediments to their advantage by hopping over them. Red foxes typically only survive three years in the wild, but they can live up to 15 years in captivity. For several weeks, fox mothers and fathers care for their young in dens, with assistance from siblings.
