It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. [1]
The European form was similar in appearance to modern populations, but was larger, being comparable in size to the brown hyena.

[11] Its direct ancestor was the Indian Crocuta sivalensis, which lived during the Villafranchian. [12]
