Hyenas look a lot like dogs, but they're actually more closely related to cats! However, they cannot retract their claws like cats can.

In hyena society, females outrank males, and baby hyenas inherit their mothers' ranks. That means babies outrank adult males!

Contrary to what you may have seen in cartoons like The Lion King, it's more likely for a lion to steal a kill from a hyena than the other way around.

A hyena's jaw is strong enough to chew through bone! This allows them to eat bone marrow.

Hyenas are very smart! When it comes to problem-solving, they can outperform chimpanzees.

Hyenas have a complex society and social hierarchy, much like monkeys.

Hyenas can live into their 20s!

Hyenas can identify other individual hyenas by their distinct whooping sounds.

A group of hyenas (called a clan or a cackle) can consist of up to 80 individuals.

Source: I don't know, I've known a lot of these for a while and I just have them at the ready if an opportunity to share hyena facts comes up. Some are from the book The Hyena Scientist by Sy Montgomery and others I saw online and triple-checked to make sure they weren't bogus.
