Initiating translation of Aquatic Echoes:
I have seen humans in their aquatic attire. They are peculiar creatures.I will attempt to describe them.
From what I have observed, the human body is divided primarily into five main trunks attached to a central locus of sorts. These trunks are not equal in size, length, strength, or function, and the most prominent of these trunks is also the shortest. This shortest trunk is located at their upper extremity, as they must remain upright at all times. This upper extremity is topped with a protective covering. This extremity is protected because it seems to house the majority of the sensory and, likely, the motor systems. Humans appear to respire through three holes in the front of this upper extremity. Their visual sensors are housed inside two forward facing cavities, and the aural sensors are located on the sides of this extremity. Unfortunate to have all of that important function in one place, but so it is, no creature has control over their evolution at this stage of societal development and I can only hope they do soon for their appearance is surprising at best.
Humans have developed a protective fibrous covering on this upper extremity to protect from light, weather, and, what I can only assume, are attacks from other species—the most probable culprit being avian species, though I have never observed an attack. The females have much more of this fibrous covering on their upper extremity but lack it elsewhere. The males want for lack of the protective covering on the uppermost part of this upper extremity but find it in abundance elsewhere on their body. This fibrous armor seems ubiquitous amongst many terrestrial species as they all likely share a common ancestor, but it is curiously lacking in aquatic species. Terrestrial species seem more prone to develop armor as the gaseous atmosphere which they inhabit does little to protect them from sol-three’s arid environment or weather.
Humans are mostly made of pairs, and the remaining four trunks are quite similar. They taper off and separate into twenty thinner, more frequently jointed limbs (five on each of the four main trunks) allowing for greater dexterity. There are hardened protective coverings at the top of each tiny limb, though not the of the fibrous material you find on the upper extremity. The tiny limbs are quite stubby, especially on the lower extremities, but the upper limbs seem nimble and dexterous.
As humans are required to be sturdy enough to withstand the full pull of gravity they are awkward and stiff, as most land dwelling species are. Joints become a necessary for mobility, because the skeletal structure must be sturdy enough to withstand their weight.
Humans are obvious terrestrial predators, their sensory organs face forward allowing them to track prey, and they remain upright for greater mobility. Though ungainly in the water, from what I have seen through the divide they are quite formidable on land. Their movements are abrupt rather than fluid and though their outer layer is soft, it is much firmer than one would imagine. I can only think that it offers some great degree of protection in their natural environment. It would be most interesting to see one up close, I can only hope that I am near when one of them dies, for though I am stripped of my technological and societal augmentations, I am not yet so barbaric as to capture one for study; though from what I have seen the humans would have no such qualms about doing the same to me, were I ever detected.
