Giant Emerald Pill-Millipede: when these enormous millipedes are all rolled up, their bodies can be as big as a baseball, a tennis ball, or a small orange

This species (Zoosphaerium neptunus) is commonly known as a giant emerald pill-millipede. The females can measure up to 90mm long (roughly 3.5 inches), making this the largest species of pill-millipede in the world.

There is a significant degree of sexual dimorphism in this species, with the males measuring only about 45mm (1.8 inches) long -- roughly half the size of the females.

Giant emerald pill-millipedes are found only in Madagascar, which is home to several endemic species of giant pill-millipedes (order Sphaerotheriida). The Malagasy name for giant pill-millipedes is "Tainkintana," which means "shooting-star."

Pill-millipedes use conglobation as a defense mechanism, which means that they can curl their bodies up into a spherical shape so that their dorsal plates form a protective shield around the softer, more vulnerable parts of their bodies, just like an actual pill-bug or a "roly-poly."

When they roll themselves up completely, they look almost like gently polished chunks of malachite, emerald, or jade.

Giant emerald pill-millipedes will sometimes form large swarms that travel together as a group. This is the only species of giant pill-millipede that engages in any sort of swarming behavior, and the purpose of that behavior is still unclear. The swarms often contain thousands of individuals, with almost all of them moving in the same direction, even when there is no physical contact that might allow the millipedes to "herd" one another along.

Their swarming behavior also has some very peculiar features, as this article explains:

During swarming, Zoosphaerium neptunus individuals pay little attention to their surroundings; many specimens were observed walking straight into and drowning in small puddles. Some swarms even display ‘cliché lemming behaviour:' in Marojejy, a large part of a swarm walked into and drowned in a small river.

No single specimen was observed walking ‘against the current,' all specimens were moving in the same direction (southeast), even when not in contact with one another.

Of 273 randomly collected individuals, 105 were males, while 168 were females. The males were 8.3 - 14.1 mm wide (average width 10.4 mm). According to the inner horns of the posterior telopods, all males were sexually mature. The females were 9.95 - 15.4 mm wide (average width 11.4 mm). All females displayed non sclerotized vulvae and were sexually immature.

Some researchers argue that the swarming serves as a defense mechanism, providing a layer of protection (or at least some cryptic cover) against local predators, but the swarming behavior is still poorly understood.

Important Note: I just want to remind everyone that these animals belong in their own natural habitat -- they should not be trapped, bought/sold, traded, shipped, collected, or kept as pets. This particular species does not survive well in captivity, either, and the demand for these "exotic" invertebrates is putting the wild populations in jeopardy. The previous article discusses those issues, too:

Another possible threat for Z. neptunus swarms are collections for the pet trade. There exists a large demand in Japan, Europe and North America for 'green -eyed monsters’ as pets. Giant pill -millipedes from Madagascar unfortunately have a very short survival time in terraria. The species is specialized on low-energy food (dead leaves), and adapted to the cool climates (<20°C) of the highlands. Specimens in terraria often starve to death quickly.

So I know that they're adorable and really, really fascinating...but let's just let them be their chunky, adorable little selves out in the wild where they belong.

Does anyone else have an list of 10-15 untouchable thoughts that if you let yourself remeber or think about them for even a second it’s excruciating or is this a me thing

me, seeing someone left me a comment: screaming, running around the room in circles, kicking my feet up in the air, jumping up and down, giggling to myself, squealing, wiggling, dancing around...

me, replying to someone's comment: Thanks! I'm glad you enjoyed it. :)

I don't understand how people just Do things without daydreaming. like how are you not off in a silly little fantasy world rn

Absolutely nothing worse than finding out that you share interests with someone you hate. Has you thinking things like fuck you I'm better at enjoying star wars than you are

[insomnia-productions]

Curious as to just how many people have watched this fandom juggernaut

Listen, I completely understand why it was an issue for some people, but I still think that naming the original release of Deltarune “SURVEY_PROGRAM.exe” was really really funny

Sure you know what. All other popular social media platforms suck ass but you don't need to ride Tumblr's dick because this platform also very much sucks ass too

my friends and I have created a game we call Quipposting, where you play quiplash but you roll a wheel full of character archetypes, and whatever it lands on, you all answer as if you are like, a wizard or cowboy. This legitimately makes quiplash go from a fun enough game to an S+ tier absolute unabashed banger

The point of fiction is actually to put that guy in a situation™️, and he might try to tell you the point is to then get him out of the situation, WRONG, second situation

Absolutely captivated by this very specific type of image

no offense but you guys need to learn the difference between someone implying their experience is universal and a post simply just not being about you
