They began forming increasingly larger territories, necessitated by the fact that their prey was often migratory, and long chases in a small territory would have caused them to encroach into another clan's land. Home ranges are defended through vocal displays, scent marking and boundary patrols. If you saw a spotted hyena loping back to its den with clearly distended mammary glands, you would probably guess it was a female. Tweetable facts about spotted hyenas Spotted hyenas are not the same as striped hyenas or brown hyenas. When fossils are taken into consideration, the species displayed even greater variation than it does in modern times, and a number of these named fossil species have since been classed as synonymous with Crocuta crocuta, with firm evidence of there being more than one species within the genus Crocuta still lacking. Dispersal status influences hormones and behavior in the male spotted hyena. In case you're wondering, I did not share any of this lurid detail with my mother-in-law. Subscribe to our newsletter.
