Scientific Classification: Lutrozia aratas
Lifespan: 110 years
Speed: 24 kph
Height: 175 cm (male), 165 cm (female)
Weight: 55 kg (male), 50 kg (female)
Anatomy and Physiology
Cexhils have four arms, two legs, one set of genitalia, a torso, a neck, and an elongated head. Their facial features are strikingly reminiscent of humans, with very sophisticated eyes, short noses with two nostrils, a narrow mouth and twenty-four bony teeth.
The Cexhil's first set of arms, protruding from the shoulders are double-jointed at the elbow. They are capable of bending in both directions to a maximum of 235 degrees. Their second set of arms protrude from the top of the pelvic plate, and are significantly shorter, have only a single joint at the elbow, but are considerably stronger. All four arms have a single-jointed wrist and a palmless hand with an opposable thumb, and three long fingers.
Cexhil bodies are lithe and covered in small scale-like chitinous plates. The "skin" of the male specimens appears to be thinner, allowing them greater mobility, whereas on the female Cexhil, it is thicker, no doubt to protect their offspring when in utero. Their sexual organs are surprisingly similar to those of humans. The Cexhil penis is very long, and stays erect all of the time, but is protected within the pelvic plate. It is the only part of the Cexhil male that is fleshy and uncovered by the hard exterior plates. The Cexhil vagina is not at the apex of the legs, but rather in the front of the abdomen, approximately where a naval would appear on a human. Childbirth occurs after a six-month gestation period, and is usually quite quick and painless. Cexhil infants are only half the size of a nine-month term human infant. Cexhils typically give birth to three children at a time.
Cexhil legs are very similar to those of a human, only longer. The knees, unlike the upper arms are single-jointed, and the heels rest firmly on the ground and narrow sharply to long four-toed feet.
Internal systems are similar in many ways to a human, with sophiscated nervous, digestive, immune, integumentary, muscoloskeletal, urinary and the aforementioned reproductive systems. The cardiovascular, circulatory, endocrine and lymphatic systems exist, essentially as one system.
Cexhil blood is viscous and inky-black in color. This is likely attributed to their large, six chambered heart, needing to pump only three times per minute and up to only ten times in moments of duress.
Cexhil do not have lungs like we do, and they do not need to breathe, rather oxygen is taken into small sacks underneath their skin. Fascinatingly, they can go without oxygen for hours at a time, though not without some temporary loss of motor functions, in relation to how long they have been deprived of it. As "breathing" in not an autonomic function, an evolutionary measure protects them with their bodies are submerged in liquid—essentially a semi-permeable membrane, that allows them to exhaust carbon dioxide, but does not allow fluids inside.
Cexhil DNA is mysterious. Instead of the double-helix formation that we are so familiar with, the Cexhil DNA appears as a series of blooms, attached by several strands. Despite the more complex structure, their lines of DNA are actually much simpler than earth-borne creatures. However, it makes them much more resilient to mutations, and the effects of radiation. It has been surmised that Cexhil and the other species of their world may have gone through a very slow evolution, perhaps half again longer than that of humans.
