//Memo on the subject of arachinaye-human hybridization.

Part the first: on hybridization.

Given the mastery of human medical practice over the human genome, it is theoretically possible for an arachinaye and a human to produce a hybrid offspring. For the purposes of this memo, such a theoretical hybrid offspring will be referred to as a drider. It is important to note that this is not in any way an official species name, as no such species yet exists.

On the genetic front, there are gross similarities between the arachinaye and human genetic structures. Both use a quartet of genetic nucleic acids (GNAs) in the DNA structure, with a fifth present in the RNA structure. in both species, these GNAs are largely compatible, though the RNA-excusvie GNAs are mutually exclusive in that they will not bond to any GNA from the other species without catalytic assistance. This difference is overcomable: it is expected to require medical assistance, but it is not impossible that such a drider could occur without medical intervention. As the old saying goes: life finds a way.

On the physical front, there are complications however. Arachinaye are a mono-gendered species, with every individual able to produce offspring. They do commonly require intercourse between two arachinae to produce offspring. However it is worth nothing that a) single aracinaye individuals impregnating themselves is possible and documented (possible vestigial survival mechanic?) and b) a pair of aracinaye will typically impregnate each other, and then proceed to lay a communal clutch once the eggs have hardened enough to survive laying. It is also worth noting that aracinaye ovipositors deposit unfertilized eggs, and that aracinaye "egg-pouch" (literal translation, no scientific equivalent) completes the process of insemination.

Humans are, by default, a two-gendered species when it comes to reproduction: male and female, requiring a mating between the two to produce offspring. (This author is not qualified to comment on psychological matters, and will refrain from doing so.) The male provides the inseminating material, and the egg does not leave the female's body. This of course leads to interesting physical conundrums when it comes to mating practices between an arachinaye-human pair, but the author will set those aside for the moment in favor of examining in-vitro options first.

Given that the hypothetical arachinaye-human pair do wish to conceive, the author expects that medical intervention would be needed in the development of the drider-child, both inside the in-vitro 'womb' and shortly after 'birth'. This would *not* be to determine the gender of the drider, or to in any way manipulate it beyond what the Beowulf Code of Medical Ethics permits. Instead, it would be to ensure that the drider-child would develop in a healthy manner. Expected complications that would require intervention would be the presence of excessive hair inside of the egg, the unborn drider-child rupturing the egg before birth, and / or the presence of extraneous or vestigial limbs.

Moving on to complexities with 'surrogate' pregnancies: in this instance the hypothetical arachinaye-human paring has elected to have the eggs carried to term / laying-stage inside a living individual. Which would occur is unknown at this point due to a lack of scientific documentation. The first complication that occurs to this author, outside of the inherent complexities of monitoring the development of an unborn inside of a mother, is the size of the biological organs involved. Arachinaye "egg-pouches" are large enough to contain one arachinaye's worth of eggs, which would make the arachinaye half of the arachinaye-human pair the logical egg-bearer. The human half, if female, could be expected to carry at most two eggs, given the average size of an arachinaye egg at time of laying. This authors recommendation would be a one-egg maximum however, to reduce the risk of one egg crushing another inside the womb.

Natural pregnancies are not expected, but this author would presume that medical intervention would be needed in line with the complications and complexities listed above.

Part the second: intimate interaction safety measures.

a necessary tangent to Project Hybreed's mission of facilitating the production of hybrid offspring, such as the hypothetical drider child of an arachinaye-human pair, is the needed safety precautions should the pair wish to have intimate interactions. Given the complexities listed in part the first of this memo (see above), such intimate interactions would not be expected to produce children without medical assistance. Such endeavors would not be without risk, baring suitable preparations and precautions, which are covered in some little detail below.

On arachinaye physiology (re: this subject):

Arachinay have eight legs on their abdomen, which is carried horizontally to the walking surface, as well as two manipulator limbs on their torso, which is carried perpendicular to the walking surface. This 'taur' configuration carries with it the usual difficulties (see memos: Hextaur Anatomy Issues, Serpentinia Tail Issues) which have the usual solutions for a human partner. Avoid being crushed by not being underneath your partner when / if they collapse post intimate interaction. Mind the extra limbs, mind the potential strength difference between individuals with a size difference.

Of particular importance for a human interacting with an arachinaye partner in an intimate manner are the following: arachinaye foot-claws, spinarettes, and fangs / venom.

Arachinaye foot-claws are approximately as hard as terran equine hooves. They are dense enough to be considered dangerous, particularly in light of the strength inherent in arachinaye legs, but it is their points that could prove most dangerous. Arachinaye foot-claws are pointed, the better to bite into the bark of the super-giant trees on their homeworld, and those points can puncture soft surfaces should enough weight and / or force be put on them. in the process of intimate interactions, care should be taken that the aracinaye's foot-claws are not put anywhere tender or penitrateable with any pressure.

Arachinaye spinnerets are not related to sexual interactions, but are worth noting for their sensitivity and the silk that they produce. Arachinaye spinners contain large bundles of sensory receptors, predominantly pain, pressure, and temperature oriented. Accordingly, it is advised to handle them with care. The silk that is produced by arachinaye spinnerets can be sticky if and only if that arachinaye chooses it to be so at the time of production. it does have remarkable tensile strength (est. 2.5x to 3.75x terran web-making spiders) and a surprising resistance to being cut. Arachinaye individuals are known to make their clothing from this silk, as its durability means that only arachinaye saliva can break it down and / or cut it with any ease. Should such silk be used during intimate interactions, be mindful that it will be difficult to break should the need arise unexpectedly.

Arachinaye fangs and the venom that they contain are the most dangerous feature to consider in any set of intimate interactions. Arachinaye are, naturally, immune to their own venom, and are hard-chittened enough to resist bites from other arachinae. Individuals from equally hard-skinned / plated / exoskeletoned races need not worry overmuch, but humans are decidedly squishy and puncturable by comparison. An average arachinaye bite will penetrate as much as 3.25 centimeters into the flesh of its target. This is enough to cause serious damage to a human. As such, one of two methods is recommended to avoid this tragic eventuality:

1) Do not get bit. This is, of course, dependant on the individuals involved. In particular their intimate interaction habits and restraint during times of high emotion.

2) Use a mouth guard or other bite inhibitor. While such pieces of protective equipment may intrude on intimate interactions, they are preferable to a required hospitalization due to flesh wounds and blood loss. Some bite inhibitor equipment, such as gags, have social connotations associated with them. Partners are advised to communicate before using them.

Arachinaye venom is dangerous to humans. While not immediately lethal in most cases, Anaphylactic Shock is a concern with some individuals. Even in individuals where this is not the case, Arachinaye venom does have painful and debilitating effects if left untreated. Anti-venom treatments are available at most hospital facilities, but their presence is not guaranteed. To prevent this interaction, the use of a venom-draining kit is strongly recommended. Most major pharmaceutical stores carry them, as do some convenience stores that cater to non-human hygiene needs.

//Memo Addendum / notation: full-function multi-gender humans

It is theoretically possible that a modified human would have a higher chance of producing a drider offspring with an arachinaye. The presence of fully functional male and female genitalia on both individuals in an arachinaye-human pairing would, in theory, raise the odds of likely conception by multiplying the possible number of intimate interactions. This author declines to speculate on the nature of said interactions.
