MECHANOIDS: A SHORT PRIMER ON XENOBIOLOGY AND XENOCULTURE OF
Drawing, above: A depiction of a mechanoid drawn by Martian Ecumenopolis artist @summonfish for use in extraterrestrial studies. Non-juvenile mechanoids can be broken down into 6 major body locations: The forelimbs (or limbs, or overlimbs), the hindtentacles (or hindtendrils, hindlimbs, or underlimbs), the torso, the dorsal nodules, the neck, and the head.

For those that have not specialized into terranautical, xenocultural, or xenobiological areas of study, a small primer: Mechanoids are silicon-based extraterrestrial life forms discovered on a satellite body within the GJ 273 system. They are sentient and sapient chemotrophic organisms that do not utilize any biological mechanisms recognizable to us except in the abstract - this includes both very basic building blocks such as protein and enzymes and higher-level structures such as bones, nervous systems, blood (or blood analogue) and so on. They do possess roughly similar analogues for most of these things, however, that allow them to communicate relatively easily with human xenoculturalists, xenoanthropologists, xenojournalists, and the like. The exact details of these functions are outside the scope of this primer.
Despite the name, mechanoids are not "mechanical" or at all readily robotic in character, the species name being a readily-caught-upon misnomer from first encounters. They do, however, possess a metallic countenance similar to the scaly-foot gastropod due to their chemotrophic habits, resulting in the confusion. Mechanoids "feed" by absorbing gaseous chemical compounds through their dorsal nodules and absorbing liquid chemical compounds through their underlimbs.
The home satellite of the mechanoid species is a rocky and metal-rich moon with a thick atmosphere. Their home star's low luminosity and the high albedo of cloud cover on their home satellite produces a relatively cool environment with massive, kilometers-wide "sulfur fogs" rolling slowly over the surface akin to waves in an ocean - it is on these sulfur fogs which mechanoids subsist. Large, mineral-rich underground caverns contain thick, high-temperature sulfur lakes in which nesting mechanoids deposit their eggs during the mating season.

Mechanoids only recently begun to understand the concept of "other species", as they are the sole living things on their home satellite. They have developed what could be considered to be pre-industrial society, and several of them have become expatriates in nearby colonies for the sake of cross-cultural exchange. Mechanoid architecture is sparse, with most using the natural caverns that their home satellite has provided them with rather than construct any dwellings of their own.
Mechanoids are capable of visual perception, fine manipulation (primarily with the two largest hindtentacles in the front of the cluster), and communication. They also possess chemoreceptive and magnetoreceptive senses, but do not have a sense of taste or olfaction and have a powerful sense of electroreception that adequately functions in replacement of the senses of touch and proprioception, and while they have what could be described as a "sense of hearing", its mechanism is particularly alien when compared to our own. Mechanoids are not capable of speech but can generate a variety of mechanically sourced noises, with which they have developed a language not entirely unlike morse code which is still being analyzed and deciphered today.
Pictured above: A mechanoid news pamphlet describing first contact with human terranauts (see the artistic depiction in the third paragraph). Mechanoid written language uses chemical inks arranged in rectangular chunks akin to barcodes for written word, which are read with the hindtentacles. Pages are typically rectangular, spread wide with the primary two hindtentacles, and are read clockwise from the bottom-left.

Mechanoids are long-lived, with the oldest recorded mechanoid living to approximately 630 Sol-system years. They hatch from metallic, rigid eggs laid in clutches of 3-20 - upon hatching, a small crack will form along the softened underside laid in boiling sulfur, and the body will be squeezed out, before the egg re-seals itself with the head still inside. Over the course of around two Sol-system weeks, the metals in the eggshell will be "digested" for development of the exoskeleton analogue, leaving only the distinctive translucent, egg-shaped head. After which, further development only causes increases in size and wisdom, and decreases in translucentness of the various membranes.
Pictured, above: A juvenile mechanoid looking into the camera. Note the translucent exocranial membrane and visible light-receptor (and its reflection on the exocranial membrane). The silhouettes of its parental units are visible in the background through the sulfur fog. Mechanoids are born without forelimbs, requiring the care of their parental units until they develop all three at approximately 4 Sol-system years from hatching, after which, they are considered "adolescent" and will leave to join wider society. Mechanoids are genderless and highly socially mobile, with a large societal taboo against mating with the same partners more than one mating season in a row (although, of course, many do like to play favorites and return to old flames frequently).

Mechanoids arrange themselves in "clusters" of individuals that typically encompass an entire settlement (or several). Mechanoids usually possess 1 "primary mate" that contributes approximately 50% of the genetic material analogue, anywhere from 1-4 "secondary mates" that collectively contribute approximately 25% of the genetic material analogue, and anywhere from 1-8 "tertiary mates" that collectively contribute approximately 12.5% of the genetic material analogue, with the mechanoid in question contributing the remaining 12.5%. Mechanoids can and frequently do contribute to multiple mating clusters per season, forming an intricate, and, apparently, drama-laden web of intrigue and connections.
Pictured, above: A subsection of a mechanoid brooding cavern with 6 eggs visible. The eggs on the lower left and upper left are close to hatching, as shown by the visible light receptors peeking through and the distorted shape. The mechanoid's preserve world has few flashes of color - except for these sulfur rich underground nests, where they lay their eggs. Multiple clusters of mechanoids will meet at a single hatchery to lay eggs during mating season, remaining for approximately 8 Sol-system weeks to perform the "egg sponsorship" ritual, where clusters will select at least one egg from each other present cluster's brood to adopt into their own. Mechanoid culture dictates that having more of your eggs sponsored is a greater indicator of status and fitness. During the mating season, each present cluster is defined by its primary-coupling, with secondary and tertiaries that are a part of multiple clusters slipping away to the ones they find most affinity with for the season.
As you can see, despite their strange appearance and unusual biology, mechanoids have quite a lot in common with us humans, and are nothing to fear. Mechanoids are known to appreciate the human visual and auditory arts, and rudimentary human dwellings have begun to be imported to major population centers. If you have the opportunity, supervision, and permission, I highly recommend you take a trip to the mechanoid satellite - if nothing else, but to help the continued flow and exchange of cultural knowledge between both of our species.
