Arachnids

Arachnids are members of a broad class of organisms that are very familiar to humans. The organisms in this class range from the common spiders to scorpions to ticks and mites. However different these organisms are, they all share one common characteristic, they all have eight legs. Questions and answers about the class and the organisms in it should be placed in this category.

Do arachnids have male reproductive organs?

Yes, though none have a penis. In general sperm is produced in the genitalia at the underside of the abdomen, and the male arachnid transfers that to his pedipalps (in the case of spiders at least); pedipalps are the frontmost pair of appendages next to the mouthparts. Later, he inserts his pedipalps into the female's genitalia on her underside and mates this way.

Which is more toxic a small scorpion or a large scorpion?

All scorpions have venom; let's just get that out of the way. Their venom is not a defensive mechanism (meaning, they didn't evolve it to protect themselves from us), it's how they catch their prey. This means their venom is adapted to neutralizing the things they normally eat -- namely, invertebrates. So first off, a scorpion's venom isn't really tailored to affecting humans. Very small scorpions such as the bark scorpion found in Southern Florida can sting and the sting is painful -- but, like a bee sting, goes away with little more than localized swelling. The issue with very small scorpions is they literally cannot inject enough venom to affect a large human. Think of dropping a single drop of red food dye into a big bucket. There's so much water you won't even see the color. On the flip side, very big scorpions tend to rely on their pincers more than their venom to neutralize prey as pincers are not as costly as venom and don't require them to constantly replace them. Therefore, their venom is weaker and not nearly as potent. The best predictor of how strong a scorpion's venom is is not the size of the scorpion but rather the size of their pincers in relation to their body. An emporer scorpion, for example, is huge, but has huge bulky pincers and very, very weak venom. Another scorpion with more slender, delicate pincers is not using their pincers to catch their prey and will have a more powerful venom. Always remember that if you'll be travelling to a place with scorpions, do a quick check on the local species to get an idea of what level of danger they pose as well as what precautions you should take in dealing with them (not leaving clothes on the ground, shaking out shoes before putting them on, etc). Many scorpions are harmless or pose very little threat, but there are a few deadly kinds -- but most importantly, a scorpion won't bother you if you don't bother it.

Is a male Black Widow poisonous?

Yes, the male Black Widow has venom. But they are very shy, much smaller than the female, and much less aggressive. Their diminutive physique means they have small fangs, small amounts of venom, and they can't deliver the kind of deep bite (and high venom volume) that the female can. Unless you saw a male Black Widow in the web of a female courting it, you'd likely never notice or otherwise encounter one. A link can be found below so you can at least see a picture of a "couple" of these arachnids. You're looking "up" at them from their ventral side, and the red hourglass of the female is very apparent.
