Description

(this is a concept, and may be changed in the future)



Much like we humans, the Shrith are supported by a sturdy endoskeleton, with the bones being made of a similar composite to human bones. In addition, Shrith bones are also of a similar density to human bones. But the actual skeleton itself isn’t so similar to that of a human’s in some aspects.


At the front is a skull. Not too surprising, as it houses and protects the brain of the Shrith. In the skull is a large, gaping hole. In life, Shrith have obvious muzzles, but these muzzles are made of a soft cartilage-like material, similar to the human nose. When stripped of skin and flesh, the Shrith skull is left with a big hole in the middle, this hole resting below two smaller holes. These smaller holes above the nasal hole are ocular holes. They do not hold eyeballs, but rather serve as an anchoring point for the Shrith’s eyestalks. Lastly, the small holes at the side of the skull are ear holes. 


Beneath the front of the skull is the thrummer, a small bone that plays a key role in Shrith phonation. Derived from a protective sheet of bone, the thrummer, in the derived Shrith, vibrates super quickly and produces vibrations, which adds “voice” to the phonemes. The thrummer itself is one of the few bones that doesn’t directly connect to the main skeleton.


The skull is connected to the thorax via several small vertebrae. Similar to insects, the Shrith body consists of a head, thorax and abdomen, with all the limbs being connected to the thorax. The entire thoracic limb girdle is one piece, resulting in pretty much no flexibility in the thorax. But regardless, while much of the thorax is inflexible, the “ribs” at the top of the limb girdle, which protect the lungs, are capable of expanding and contracting via cartilage. As for the rest of the limb girdle, the walking limbs connect to the limb girdle via ball-and-socket joints. This is also the case for the vestigial third leg. All Txemshi vertebrates are either “two-leggers” or “three-leggers.” All two-leggers are derived from three-leggers, which has resulted in the thoracic limb girdle of two-leggers being differently shaped than that of the three-leggers. The third leg in two-leggers, like the Shrith, has shrunk down and is no longer used in locomotion in any way. As for the remaining walking limbs, they consist of one bone, two bones and then a bunch of little bones, like human limbs. Lastly are the wings. The wings themselves are the only limbs that don’t connect to the skeleton directly, and the wings are instead connected to the skeleton through muscle. 


Lastly is the abdomen. The abdomen, unlike the thorax, is supported by a chain of vertebrae with “ribs” at the side. These vertebrae allow the abdomen to move side-to-side. While useful to the “fish” of the world, terrestrial Txemshi vertebrates don’t really need flexible abdomens, and so their vertebrae have elongated a little, as evident in how Shrith abdomen vertebrae are longer than their neck vertebrae. As for the “ribs,” they give further structure and protection to the abdomen, but they are not connected like how human ribs connect to the sternum. Shrith have no sternum, and so these “ribs” are connected by muscle, which allows the abdomen to expand and contract a little as the body needs.
