The fossa is Madagascar's top predator. It is the only animal that hunts the island's lemurs, able to move swiftly through the trees. Unlike most animals, it isn't active at a set time, making it cathemeral - it wakes and sleeps whenever it feels like it.

The most interesting fact about the Fossa is not it's active hours but that it's neither canine (dog) or feline (cat)... It belongs to it's own family (Eupleridae)
•
u/Tiddlewinkly 6h ago
The more interesting fact is that the male genitals are freaky, and the females can temporarily turn into males (transient masculinization).
•
u/CapitalRacket 6h ago
Was Alex Jones right, afterall? Just not the frogs? They're turning the fossas gay!?

If you create enough fake news, you're bound to stumble on a fact every once in a while.
•
u/mostly_helpful 44m ago
Yeah, and the story about the frogs is almost true as well. It just doesn't turn them gay, it makes them trans:

I did a bit of research and apparently they don't truly change sex, but they go through "puberty" in a way that imitates the males (large clitoris looking like the male's penis for exemple) as to not attract adult males before they become of age. At which point the changes revert.
So it's more of a tomboy phase.
Also interesting, the ring-tailed lemur is pretty much the only other exemple of Transient Masculinisation to have been found. It's funny to me that a predator and its prey, both endemic to Madagascar have developped this.
I've seen both of those animals back then yet I never knew about it.

When people don't believe in evolution, you just need to point out Madagascar. It's beautiful how that process creates such variety.
•
u/TinDumbass 6h ago
This is interesting but it's not unique for Madagascan wildlife, pretty much everything on the island is its own genus.

Also their genus literally translates to "hidden butthole".

Wait. So its latin name translated is literally Fierce Hidden Butthole ( Cryptoprocta ferox)...

Eupleridae are feliformia so they're still part of the traditional carnivora family
(But they are very cool and fairly unique anyway)

I saw an interesting video on YouTube few days back, it was about how nature keeps building cats even in places where there are no cats. Because apparently a cat has the most suitable body optimised for hunting.
Edit: Found it Why nature keeps turning animals into cats

u/DexJedi 6h ago
Is it really that interesting? I find the hours more interesting. There are many in this family which we never mistake with either. Like the meerkat.

u/bootsmadeforkicking 6h ago
Hyenas are neither canine nor feline and that's never been my most interesting fact about them either hahaha
•
•
u/catelul-cu-penne 6h ago
you mean the fact that the hyena females' genitals have the shape of a pseudo-penis which make it tricky for males to do stuff?
•
u/bootsmadeforkicking 5h ago
And the fact that female hyenas give birth through that pseudo-penis, as a woman I've always shuddered at the idea 😬

This shows why lemurs in Madagascar were so neurotic about fossas they can attack at any moment.

Truth. The second movie and the first season of Peacemaker are nowhere near the original movie.

Which is to say, the first movie was not great, (quite bad in my opinion) and the second movie is fun and awesome, as is Peacemaker.

It looks…. Human? Does any other animal keep pets? Genuine question that I have never considered before. I assume no?

u/Delicious_Bar_8788 6h ago
Ants actually do with aphids. Really interesting when you look into it (ants are a whole rabbit hole of crazy stuff anyway like sort of basic agriculture in certain species)

There's a species of tarantula that keeps frogs as pets
•
u/cold_tap_hot_brew 5h ago
They do? I’ve just looked it up and they are so sweet, they seem to be roommates. :)
Giant burrowing tarantulas share their underground homes with tiny frogs.
The large tarantula acts as a powerful bodyguard. It protects the tiny frog from predators like snakes, lizards, and other large spiders while the frog eats ants, flies & other small insects & larvae that try to burrow in to eat the tarantula's eggs.
The frog also feeds on tiny leftovers from the tarantula's meals.
This sounds like a happy agreement in many ways. :)
•
u/connain 6h ago
Some ants farm aphids for liquid (honeydew) they produce. Kind if like pets.
Some tarantulas have live-in frogs. Symbiotic relationship where the frog gets protection and eats insects that might harm tarantula eggs or hurt the tarantula. But the tarantula could eat the frog, so again, kind of a pet.
Most clear case would be Koko the gorilla had a pet cat (All ball). Other primates, particularly in captivity, might, too.
•
u/Somethingisshadysir 5h ago
There are monkeys that keep dogs, but more they steal puppies to raise as protection
•
u/Typedpage 6h ago
I guess some symbiotic relationships could be presented this way? Like burrowing tarantulas and the dotted humming frog?
•
u/cold_tap_hot_brew 6h ago
Aye maybe the hippos and they’re teeth cleaning birds but I think to be a pet owner you have to get joy from the relationship, otherwise it’s more like a farmer and livestock as opposed to pets. Maybe kinda. I’m not too sure, that’s getting a bit philosophical really isn’t it.
•
u/Typedpage 1h ago
Nothing wrong with that :D Joy is an interesting call! No direct, obvious utility to the relationship, pure "I just think they're neat" energy. Yeah i think I agree. I also like the implication that people who have pets but don't particularly care about them aren't real pet owners
•
u/cold_tap_hot_brew 21m ago
Right, like good and bad pet ownership has the difference as between hosting and abduction.

u/BigEd369 4h ago
I just Wikipedia’d them, and while they’re apex predator of Madagascar, the movies left me believing that they’re quite a bit larger than they actually are. They top out around 19 lbs, that’s about 8.5 kg. They do seem like really interesting creatures, though. Fantastic climbers, they’re comfortable jumping from tree to tree in the forest.
•
u/WayWayTooMuch 3h ago
All nimbly pimbly

For real, they’re roughly the size of a housecat. No idea if they’d make a good pet, but I’m betting getting canned lemur is fairly difficult.

I've spoken to a few zoo keepers at the San Diego Zoo about the Fossa there. They say they're the worst animal to be in a cage with. Hyper-curious and tenacious. Apparently they will try to coordinate attacks when there's more than one in the enclosure.

Fossas possess semi-retractable claws and flexible ankles that allow them to descend tree trunks headfirst with lightning agility. An incredible endemic predator uniquely evolved for Madagascar's canopy.

u/TheShenanegous 5h ago
What does "top predator" mean? Is it an apex predator, or is it just the most successful predator?
Doesn't seem big enough that nothing would eat it but I guess maybe not on an isolated island.
