Observe this industrious little fellow below: While, yes, they can and do use their jaws to strike out and give a well-placed nip at an attacker, the chelicerae also have a role in a warning system to would-be fuck-with-ers. This is done through the generation of noise through vibration of physical components of the interior surfaces of the chelicerae against one another.

Solifugid chelicerae can be thought of musical instruments of sorts. Ah, nothing like the sweet sound of the guillotine guitar. But stridulation is also found in numerous groups of beetles, as well as arachnids like spiders and our lovely solifugids. This often depends on something scraping rapidly along a finely-ridged surface, generating vibration as it does so. This is the same kind of action that allows fingernails to produce sound when running along a washboard, or for the needle to relay embedded musical recording information as it moves along the tracks on a vinyl record sound which is then amplified.

The sound is generated when the chelicerae are pressed together and slide past each other, causing the bristles to drag down the file on either chelicerae…. Squeaking produced by solifugids in laboratory settings seems to occur in response to perceived threats, and is acoustically similar to the noises made by other arthropods that use warning noises against predators.

It has been suggested that solifugids stridulate as a form of bluffing. Seeing as how only males possess them, it is thought they have some sort of role to play in solifugid sex, but to be honest, no one really knows what the hell they do.

I suppose figuring that out would require researchers to get up close and personal to the gnashing jaws of a sexually ravenous solifugid. So, obviously, in solifugids, the head is more or less a battery of powerful tools for survival in the barren desert wastes.

Just the chelicerae alone function as steak knives, a backhoe, a furious kazoo, and…maybe something related to sweet, sinful, stomach-churning, solifugid sexual satisfaction? But the legs and body of these critters are equally important and full of exquisite adaptations worth addressing.

Scorpions and solifugids are close relatives, and have both become masters of the desert biome over hundreds of millions of years. However, their strategy for survival here is very different. Scorpions have a suite of adaptations to minimize their output of energy and water.

Many species can hunker down under a rock and remain in a type of stasis without eating or drinking for very long periods of time.

They move across the desert deliberately, and under the cool of night, and use their venomous sting as a conservative means of procuring food. Understanding how solifugids navigate through their world is key to understanding how they manage to survive and consume so much in a place with so little resources to offer.

Solifugids only use three of their four pairs of legs for locomotion. The first pair of legs, up near the head, are thinner and more delicate, and are usually held just off the ground and act like antennae, rapidly trailing and sensing the environment via touch as the solifugid motors along.

In front of these legs are a pair of pedipalps, appendages that look like legs, but are not, and are more often associated with the mouthparts in arachnids the pedipalps of scorpions, for example, have been modified into the pinching claws. With three pairs of appendages powerfully propelling the animal forward, and two pairs elevated in the air, the solifugid is like some kind of arachnid centaur. And much like the mythical beast, solifugids are renowned for their elegance, dignity, and…er…beauty.

Solifugids move about in this way insanely quickly, flying over the hot sands at 10 mph 16 kph …which is quite a feat for an animal smaller than an iPhone. While there are other invertebrates that, for their size, are faster than solifugids for example, the pint-sized tiger beetles come to mindnothing without bones really comes close to these speeds, which are close to what an adult human can accomplish at a sprint.

So how do they manage to do this? The answer may come from how they fuel their bodies with oxygen. Instead, like harvestmen and pseudoscorpions, they have a network of small tubes running in and out of their bodies that allow the exchange of oxygen and carbon dioxide to occur. Solifugids also have multiple pairs of spiracles holes that pump large volumes of air in and out of this network with great efficiency.

These bastards are able to visit blistering, swift death upon everything that creeps and crawls under the desert sun because when evolution was passing out engines, they got the 8.

Part of this is facilitated by the vice-like grip of its chelicerae, but that requires getting close enough to chomp down. This is where the pedipalps come in, which have eversible suction pads on the tips. These little structures stick right on the prey in mid-chase, allowing the solifugid to get a grip and pull the hapless victim straight into the torturous embrace of its esurient maw.

To get an idea of what this would be like, imagine you are a lone agama lizard, taking a night stroll on the flanks of sand dune in the middle of Sahara in search of a wayward beetle or two to snack on.

Arachnids: Solifugids

Before you can even react, a hideous vessel, festooned in flailing jaws and legs, clears the top of the dune, and races down after you. You turn to flee, and just as you do, terror grips you as you see those fucking toilet plungers of death eagerly reaching out towards you. You skitter down the dune, sand flying, your little lizard heart pounding.

The solifugid, aided by gravity, gets closer, bearing down on you, a vast tank driving a flurry of clacking car compactor claws, slicked with saliva, horrifically screeching as they rub past one another. Suddenly, you feel one of the suction cups adhere to your scaly side with a sickening wet pop, and you are yanked backwards. The sound of the rustling pincers to your back ceases right before they come down on your belly with tremendous pressure.

You let out a pitiful yelp as the solifugid silently, coldly, articulates a massive jaw over your head. It easily collapses your skull, and everything goes black. Those nifty little suction pads? Solifugids will take and eat anything they damn well please.

Flying away only prevents the inevitable in the desert. Their soft, stretchable abdomens expand with liquefied food like a water balloon attached to a sink faucet. This allows them to obtain as much food energy as possible in a very short amount of time, a skill I learned and exploited whilst around free food in my college years.

In addition to those weird flagella on male chelicerae, there are other organs adorning the Solifugae that are a complete mystery to science. Here we report a fungal farming in a non-social lizard beetle Doubledaya bucculenta Coleoptera: Adult females of D.

We found that the inner wall of the bamboo internode harboring a larva is always covered with a white fungal layer. Histological examination of the ovipositor of adult females revealed an exoskeletal pocket on the eighth abdominal segment. The putative mycangium contained yeast cells, and W. When first instar larvae were placed on culture media inoculated with W.

By contrast, first instar larvae placed on either sterile culture media or autoclaved strips of bamboo inner wall exhibited arrested growth at the second instar, and addition of W. These results strongly suggest a mutualistic nature of the D.

Based on these results, we compare the fungal farming of D.

It is widely distributed in China, and both larvae and adults can cause serious damage. It is difficult to control this pest because the larvae live underground. Any new control strategy should exploit alternatives to heavily and frequently used chemical insecticides. However, little genetic research has been carried out on A. Genomic resources could be produced by next generation sequencing technologies with low cost and in a short time.
