If there was such a thing as cat-like-urday I would release this on that day, but there isn’t. So we are going to talk about it now.
You see there are the true cats, the felidae, and then there are cat-likes, the Feliforms. Now all true cats are feliforms, but not all feliforms are true cats.
You’ve probably heard of the fossa if you’ve seen the movie ‘Madagascar’. Well the fossa (Cryptoprocta ferox) is a feliform in the family Eupleridae, this family is composed entirely of ‘cat-like’ species endemic (found only in a specific place) to Madagascar, the large island off the coast of South-East Africa. They are a clade (a natural group that can trace it’s lineage back to a common ancestor) closely related to the mongooses.
Oh, yeah. Mongooses are feliforms too! Along with meerkats, they are in the family Herpestidae, a family of cute, long, slinky things native to Africa, Southern Europe and Asia.
Possibly the most cat-like family in the feliforms that isn’t a felid is the Viverridae. Some of these species probably look quite a lot like the proailurus of the past, the progenitor species of all cats. This family is mostly made of up civet and genet species, many of which seem almost like primitive cats, with long, slinky bodies, slightly more pointed heads and coats with distinctly feline patterns.
But we’re not talking about them today. Instead we’re talking about the Hyaenidae family. It surprises people to find out these seemingly dog-like carnivores are actually more closely related to cats.
This has occurred through what is known as ‘convergent evolution’, whereby a species develops, independently, adaptations that another species already possess. Take wings and flight, for example, this has evolved convergently in insects, reptiles (in flying dinosaurs, the pterosaurs, I don’t believe there are any extant ‘flying’ reptiles), birds and mammals.
So the Hyaenidae developed these dog-like features from their own cat-like origins all by themselves and it becomes easy to see how they could be confused for canids.
There are four extant species of Hyena, the most famous is probably the spotted hyena (Crocuta crocuta), there is also the brown hyena (Hyaena brunnea), the striped hyena (Hyaena hyaena) and the aardwolf (Proteles cristata).
They all have a remarkable evolutionary history, stretching back around 22 million years, and the aardwolf is notable in its own right for being the most canid-like of the extant species, seeming to be directly related to the ancestral species, Plioviverrops, and representing what was an entire lineage of incredibly dog-or-wolf-like Hyaenas that likely existed until the true canids, from North America, found their way over into Eurasia.
However I want to focus specifically on Crocuta crocuta, the spotted or laughing hyena, probably the most well-known of all the hyena species.
The first thing I want to discuss is its hunting and diet. For one thing, the saggital crest (the mounting for the jaw muscles on the top and back of the head) is incredible. This would indicate an exceptionally powerful, crushing bite. The spotted hyena is from a lineage of ‘bone crushing’ hyenas, they are known to crunch through a carcass in about half an hour eating skin and bones that other predators may leave behind.
There is a common trope that hyenas are little more than scavengers who go around stealing kills off of lions and cheetahs. Nothing could be further from the truth, whilst it is believed the brown and striped hyena are predominantly scavengers, the bulk of the spotted hyena’s diet is obtained from hunting. In fact they are remarkable and intelligent pack hunters.
Of course they exist on the plains of Africa where every day is a fight for survival, as the most numerous big carnivore on the continent they obtained that success by also being ruthlessly opportunistic and where an opportunity to steal a kill or scavenge carrion presents itself the spotted hyena will not hesitate to take it.
So even though a few people, and some documentaries, still present hyena’s as thieves and scavengers it has been well recorded, since the 1960s and 1970s, that the spotted hyena is at least as good a hunter as the lion, if not better.
As far as their prey goes they are also intelligent hunters, seeming to have little prey preference, but definitely things they avoid (such as buffalo and giraffe). True to their canid-style convergent evolution they are chase predators, making their prey prove themselves over distances of a few miles. They can reach speeds up to around 35mph but the main chase is probably a lot slower, around 10mph. It is behaviour not unlike the African wild dog (Lycaon pictus).
They hunt alone or in packs, naturally solo hunting tends to be on smaller prey such as gazelle or hogs, whilst pack hunting (from 3 all the way up to around 20-25 individuals!) is reserved for wildebeest or zebra, animals that attempt to defend themselves.
So if they hunt in packs it stands to reason they must have some social structure. They exist in semi-matriarchal (Sometimes males and females will co-dominate, though usually females outrank males) ‘clans’, depending on habitat these can be smaller or larger with an upper-limit seeming to be around 80 individuals. Males typically leave their matrilineal (their mother’s lineage) clan and go seek a spot elsewhere around 2 years.
They are not necessarily a close knit group, with the size and composition of the group changing over time, and smaller, splinter groups often going off hunting or scavenging on their own. This is known as fission-fusion, and is also found in species like elephants, whales and porpoise or even social primates like chimpanzees.
These societies, then, are complex. Recognition of clan members, who come and go, a social dynamic of dominance and subordinance, even nepotism, with the dominant female’s offspring generally being regarded higher than others, this is a complex social situation. Similar to social primates, then, hyenas exhibit great development of the frontal cortex of their brain, the area most associated with social behaviour and social intelligence. Observations by colonists in the 19th century noted their canny ability to evade or escape traps, utilising deceptive vocalisations to either scare others away from their kills or protect their young if they are in danger. Observational studies show spotted hyenas use a wide range of vocalisations to communicate, as well as olfactory (smell) signals, such as scent-marking.
Studies on captive pairs of spotted hyena, by Christine Drea, an evolutionary anthropologist, even demonstrate that hyena are better at co-operative problem solving than even incredibly socially intelligent primates like chimpanzees! The study attached a food reward trap to a double-rope design where the ropes had to be pulled in unison in order to obtain the reward. Apparently the first pair of hyenas solved the problem within two minutes! She tried it with 13 other pairs and found that they very quickly learned to synchronise their pulling of the ropes and later examples done by hyena that had already done the exercise before showed they had a lower tendency to pull on the rope without their partner, exhibiting some understanding that the actions of the partner are vital in getting the reward.
Also quite telling is when competing, dominant females were put in the exercise together they often failed to cooperate!
Chimps and primates often require at least a reasonable amount of training to understand the exercise before they will demonstrate cooperation. The fact that spotted hyenas can independently come to a solution through a natural tendency to cooperate in order to obtain food is an astounding development in understanding animal cognition.
What this doesn’t necessarily mean is that spotted hyenas are smarter than chimps, merely that they exhibit cooperative problem solving skills that seem to be far and above our estimations of non-primate intelligence.
But I know what you’re thinking. “This is all actually informative and interesting. That’s not very We Lack Discipline. I assume you’re about to go on a long rant about persecution of animals or tell us how it eats its own shit.”
No I’m not.
What!? Spotted hyenas are of least concern to the IUCN, they’re very successful. Whilst human persecution occurs I actually trust hyenas to tell us where to go.
As for whether they are known for coprophagy (the scientific term for shit-eating) I don’t know. Maybe? It’s not a concern. I’m more mature than that.
Which is why, instead, I’m going to talk about the female and how they have an up to 7 inch clitoris known as the pseudo-penis! Big ol’ clitty ding-dongs! I’M MATURE!
The spotted hyena takes androgyny very seriously to the point that the females have a clitoris that seems to mimic the male’s penis. It’s very rare that there is a species with remarkable genitals but the hyena, especially the female, is one. They have no vaginal opening, for example, because the labia are fused into a pseudo-scrotum! So how do they mate? Well at the end of the female’s oversized clit is a main urogenital opening, through which it urinates, mates and gives birth.
Yup, female spotted hyenas give birth through their fake dick-hole!
They can even get a lob-on! The pseudo-penis is capable of erection!
This should come as no surprise in a species where their sexual behaviour shows females to be massive doms – The female is dominant, and shows a clear preference to subservient or passive males more than aggressive ones. They are promiscuous, so have no specific mate bonding, and have no specific breeding season, although births tend to coincide with the wet season.
As you might imagine, giving birth through your dick-sized-clit is not an easy affair and usually this results in a rupture. Especially since hyena cubs are comparatively large!
They can appear slightly unsightly. Their long, gangly legs (incidentally well adapted for hunting), their weird long necks (incredibly strong with good anchoring for their powerful bite, allowing them to grip prey), their sloped backs (excellent adaptation for escaping the claws of a lion by having it slip downward more often than not) and weirdly baldish faces (great hygiene for an animal unafraid to stick its head in some decomposing carrion) certainly do not make spotted hyenas the cutest looking of the feliforms.
But they are an absolutely incredible species, unfortunately much maligned by lion-friendly media such as wildlife documentaries or Disney’s ‘The Lion King’. Hyenas are not just giggling goofballs, or disgusting grave-robbers and thieves! They are a highly successful predator that happens to be smart enough to be relentlessly opportunistic. They are an intelligent and social animal with seemingly rich communication skills, cooperation skills and an ability to adapt. Spotted hyena variants were once common across Europe and Asia, and are believed to have mainly died out as a result of changing climate causing a change of habitat, a shrinking of their preferred grasslands and an increase in mixed woodlands in which their main competitors, wolves and humans, would have been a lot more comfortable than they were.
Their social behaviours alone make them a species well worth knowing, learning, understanding and studying and there is a lot we can learn about our notions of sex and gender, how we perceive ‘what nature intended’ from a species that gives birth out of its fake dick!
I think they suffer for their success, sort of like the saltwater crocodile. They’re not conventionally cute or appealing to us because of adaptations they have that make them good. They make weird noises, which make them socially more cohesive than other species. We are suspicious of their scavenging and carrion eating abilities but they’re opportunistic and intelligent, when food is scarce you take what you can get to survive and if that means digging up a human grave, nothing is sacred. They have also been known to hunt humans, and why not when we’re numerous and often easy prey?
They’re an incredible example of how, above all else, survival is key. There are plenty of cute species out there that have gone extinct. Many is the noble predator, with a clear preference for hunting a specific type of prey, who have disappeared off the face of the earth despite their so-called nobility, despite their perceived honour and despite any other virtuous traits we would bestow upon them. The spotted hyena is just good at surviving. In fact, it thrives at surviving!
I think we’re threatened by that.
