Giant Golden Crowned Flying Fox

Here is a thing that is true: bats are one of the most adorable animals on the planet. 

Here is another thing that is true: big ol' fruit eating bats are even cuter than regular bats. They look as though someone took the cutest parts of a dog, a cat, and a demon and smooshed them together with a little fuzzy vest.

But - is being super cute enough to win my respect? Let's find out.

Author's Note Dec 2020: This animal review has not fucking aged well


The giant golden crowned flying fox is sometimes called a megabat, and is in fact the world's largest bat. The name "flying fox" is not an exaggeration because they're pretty much the size of a small fox, plus they can have an up to five foot wingspan which is absolutely fucking nuts. They weigh around two and a half pounds which doesn't seem like much, but just remember we're talking about a fucking bat here. I know I said that big bats are the cutest bat but this particular species is getting so big it borders on creepy because they look like little teeny men hanging upside down when they sleep

Points: 1/1


Like many bats, the giant golden crowned flying fox spends its nights flying around, and its days sleeping and grooming in a communal roost with a bunch of other bats. What's sort of weird is that the bats that they share space with are not always the same species. One study of bat roosting behaviour focused on a mixed colony of giant golden crowned flying foxes and Malayan flying foxes. I guess my point here is that if different species of bats can live together in harmony, the rest of us can give peace a chance god damnit.

Points: 1/1


Bats are pretty cool because they live on the land and also sometimes in the sky, which means they are taking advantage of two different phases of matter for their habitat. That being said, golden crowned flying foxes only live in the Philippines in the woods, and as such have experienced a sharp population decline in recent years. Nobody was really counting them very seriously up until a few decades ago - the only historical numbers we have to go on are a few colonies found in the 1800s that were estimated to have over 100,000 individuals. Current populations for the entire species are around 10,000-20,000 so... yeah, there's definitely less of them now. According to the IUCN, they are endangered, and according to me they're probably not going to be around much longer.

As we all learned from that classic documentary on interspecific disease communication, Cujo, bats are known for transmitting some really nasty diseases to other animals. North American bats have a reputation for giving people, pets, and livestock rabies. Golden crowned flying foxes decided to take it up a notch and carry a strain of Ebola. Now, before you go and get your tits twisted and decide that maybe killing the few thousand remaining bats would be for the greater good of man, you should know this: the particular strain of Ebola that the golden crowned flying foxes carry (called the Reston virus) is not pathogenic in humans or farm animals. You could have it right now and not even know it. That's not to say that it couldn't mutate into some kind of 28 Days Later bullshit called Bat Fever and wash the stain of humanity from this earth. Here's hoping.

Points: 0.5/1 to be upgraded to 1 should the Bat Fever manifest and kill us all


Genus Acerodon, to which the golden crowned flying fox belongs, also contains four other species of giant bats, and is closely related to genus Pteroptus (also giant bats). In fact, this whole branch of the bat evolutionary tree is gigantic. There's a major split in bat classification between microbats (that is, regular every day bats that fly around and eat bugs and use radar and shit), and megabats (the huge fuck off bats that live in the tropics and eat fruit). But, the megabat group also includes some microbats, which suggests that the original bats were probably small and ate bugs, and the giganto monster bats came later.

Points: 0.5/1 for not being the original bat

Life History

Despite bats making up a good 25% of mammalian diversity on this horrible planet, I still find something really weird about flying mammals? Like??? First of all, how do they give birth hanging upside down in a cave? And what do they do with the babies? Most mammal babies are completely useless, even baby horses and stuff take a few minutes of flopping around before they can get going. Why don't bat babies plummet to their deaths right after they're born? It turns out that bats really do give birth hanging upside down and the mom has to catch the pup before it falls. And just like that, you will never again be impressed by a human's birth story.

Points: 1/1

Interaction with Humans

The golden crowned flying fox doesn't have much in the way of direct interaction with humans. Flying foxes may have been the real-life animal that inspired the Manananggal, a monster of Filipino legend that drinks blood and eats babies at night. So that's pretty cool. They're also pollinators and seed distributors and of no small importance to the persistence of crops, so there has been some big action in the Philippines lately to conserve them.

Points: 1/1

Total Points: 5/7
It turns out that these giant bats have enough going for them to earn my respect. They're big weird freaky creatures and I love them.

Basking Shark

BASKING SHARK ( Cetorhinus maximus ) Image adapted from wikipedia Original image by Greg Skomal / NOAA Fisheries Service Basking sharks are basically big whales, if whales were actually fish. Like every living human on this earth with a lick of sense, I love sharks, but I'll be honest with you, I'm real tired right now. So this is going to be a very special zoological review where instead of pitting some unsuspecting animal against my unrelenting scrutiny, I'm going to pit my exhaustion against my excitement to talk about sharks. Let's see what comes out on top. Appearance Basking sharks are really big and have giganto mouths that inspire google search prompts like "can a basking shark eat a human?" The short answer to that question is "no," and I'll get into why they have such big mouths that they don't use for eating big stuff in a bit. They are the second largest shark species, and also the second largest fish in the sea, bot

Saltwater Crocodiles

SALTWATER CROCODILE ( Crocodylus porosus ) Modified from Wikipedia; original image by Molly Ebersold, 2004 Crocodiles are big, scaly animals that live in the warm parts of the world and can eat just about anything. Saltwater crocodiles are like regular crocodiles only bigger, hungrier, and arguably more impressive. Appearance Saltwater crocodiles are not only the largest living crocodilians, but also the largest living diapsids by weight (diapsids are a group that also includes lizards, snakes, turtles, and birds). While not as long as the reticulated python or as adorable as the spectacled caiman, they make up for length and cuteness with mass, topping out at around 1200 kg (~2600 lbs for my friends south of the border). For reference, if you've ever seen a cow and thought "damn, that's a big animal", you should know that the biggest bulls are only around 1100 kg, and also that crocodiles eat cows, so fuck you. They also have bony plates on their body call

Little Red Kaluta

LITTLE RED KALUTA ( Dasykaluta rosamondae ) Original image by Marie Lochman These weird little critters were brought to my attention by my friend Jen Mawhinney of Fredericton a few years ago and have been rattling around in my brain (figuratively) ever since. I think they're pretty neat, but does my completely arbitrary rating system agree? Appearance Kalutas are unassuming mammals that look like adorable fuzzy little mice. They are not mice, but they're soft and fluffy with big eyes and pointy little snoots and whiskers and oh my god I can't even stand looking at them they're too cute. They fit in the palm of your hand and you could probably put one in your pocket and carry it around and give it little things to eat from time to time. Whoever gave them their common name (and their Latin name, which I'll talk about at length later) seemed to think that they're red but I would call them a staunch brown. So, you know, that's bullshit. Points:  0.5/
