The naga crusmala has a female head and torso on top of a long serpentine body. It has a feathered hood that comes down between its shoulders. The hood has nostril holes in the front. The same feathers that cover its hood cover the sides and back of its serpentine body. When standing upright its belly is sharply angled where it mets the ground, while its back is curved from vertical to horizontal. Its rear end is rounded off. Its tail is a small flap that covers the rear end down to the scales. Its rear end opens at the bottom like a snakes mouth. This is its vagina. It is a warm-blooded mammal.
 Skeletal system:
 It has hollow crests on the sides of the crown of its skull that curve down the back of its skull providing the structure for its hood. The front of the crests connect to the upper sinus cavities. Its upper canines are elongated and hollow. They fit into a gap between the lower canines and bicuspids. Passages connect the canines to the sinus cavities.
 Its vertebrae are larger than human normal for its torso proportions to allow for extra nerve fibers going to its lower body. Its cervical vertebrae have short ribs that stick out to the sides to support the hood down to its shoulders. The first few thoracic ribs are larger than human normal allowing for the air passages coming through the hood. Its lumbar vertebrae have floating ribs attached. The next five vertebrae are not fused together, instead they gradually elongate and develop ball and socket joints like snake vertebrae. The first of these intermediate vertebrae have large ribs that give the illusion of hips below the upper torso. The rest of the vertebrae down to the true hips at its rear end are all snake like with snake like ribs. About a fifth of the way down its body the ribs get larger, then back smaller. These larger ribs form its base. They extend forward when it is upright making its belly come straight down instead of curving like its back. Along with a specialized air sac, they support the weight of its upright body. Its upright height is human normal for its torso proportions. There are three fused vertebrae where its hips are attached, followed by a short section of tail vertebrae.
 Its femur, tibia and fibula bones are human normal size for its torso proportions. Its hip bones are elongated to keep the femurs from hitting the last ribs when in their normal folded up positions. The bones of its feet are fused together, like the bones at the extremity of a birds wing. The hip and femur bones make up the structure of the upper jaw of its vagina while the tibia, fibula, and foot bones form the lower jaw.
 Cardiovascular system:
 It has two four chamber hearts. One is the main heart located a quarter of the way down its body that pumps blood through the lungs and through the lower body. The other is the torso heart which accepts blood from the main heart and pumps it through the torso arteries, and accepts blood from the torso veins and pumps it gently back to the main heart. The torso heart increases arterial blood pressure in the torso when it is upright and it prevents blood from flowing down into the lower body when it stands up. The two hearts are not synchronized but do respond to the same stimuli.
 Respiratory system:
 It has fixed size lungs located around the main heart. It has posterior air sacs lining its lower body behind the lungs and anterior air sacs lining the lower body around and in front of the lungs. It also has two anterior air sacs in its upper torso chest cavity. Its trachea splits into four air passages where a humans trachea would start to branch apart. The air passages pass through the diaphragm and into the lower body. The two inner air passages are valved for incoming fresh air and lead to the posterior air sacs and the intake of the lungs. The outer air passages are valved for outgoing stale air and connect to the anterior air sacs and the exhaust of the lungs. On inhale, air goes thorough the inner air passages. Some of it goes to the posterior air sacs. The rest goes through the lungs and into the anterior air sacs. On exhale air comes from the posterior air sacs, through the lungs, joins with the air from the anterior air sacs and out the exterior air passages.
 It has a specialized anterior air sac at its base which is normally closed off from the air passages. It inflates this air sac when it stands up to help support the weight of its upright body.
 Its air sacs are normally half full of air making its very buoyant. It can compress its body without exhaling to control the buoyancy.
 The air passages coming from its hood from the upper nostrils connect to the trachea above the branches but below the larynx.
 Digestive and Urinary systems:
 Its digestive tract is only good for killing bacteria and absorbing water and some minerals like salt. Its esophagus comes down its torso, past its main heart and lungs, past the liver and the vestigial pancreas, to its stomach. Its stomach maintains an environment that kills most bacteria and other parasites. After the stomach comes the duodenum then the short vestigial small intestine. The large intestine is where the absorption occurs. After that comes the rectum and finally the anus underneath the tail. It gets nutrients through a feeding tentacle in its uterus. The feeding tentacle must connect to a feeding parasite.
 Its kidneys lie staggered to either side of the large intestine. The urethra opens up below the anus underneath the tail.
 Reproductive system:
 Its uterus lies beneath most of its other organs, beginning just behind its lungs and ending at the cervix. It has many folds in it so it can expand to fit something its own empty volume (if it can fit through the vagina). The gaps in the folds are filled with saline. Its uterus is highly innervated and sensitive to touch. It does not have a menstrual cycle, the uterus is always ready to receive organs or blastocysts.
 Most of the tentacles in its uterus are cleaning tentacles. They have tiny mouths that collect dirt and bacteria and sweep them up to the esophagus. They move autonomously over the walls of the uterus and over any foreign object it takes into its uterus.
 The breathing tentacle has two air passages, one connected to the fresh air passages and one connected to the stale air passages. They are valved so that inhaling gets air from the fresh air passages and exhaling sends air to the stale air passages. Each passage has it's own larynx so it can talk whether the subject is inhaling or exhaling. There is a small sounding chamber near the tip of the tentacle that contains a tongue and lips. It can speak through the tentacle or through its upper mouth, but not both at the same time. The tentacle has a single ear canal between and above the two air passages. The tongue can be inserted into the mouth of a subject to take a cell sample for cell processing.
 It has organs in its body, from its base up to its diaphragm, that can process cells and examine their DNA and epigenetic markers. This information is presented to it through its visual cortex, when its eyes are closed, as a set of molecular structures. Motor commands to the eyes allow its to focus in on a specific spot of the structures and scan through the structures. The organs can record a set and associate it with a specific memory for recall at any time. By recalling two sets at once, a difference pattern is generated. This difference pattern can be applied to a third set. By visualizing separating a set the organs can simulate the effects of mammalian male meiosis on the set, creating four new haploid sets. By visualizing joining one of the haploid sets to another diploid set, they simulate the effects of mammalian female meiosis on the diploid set, then creation of a zygote from the two haploid sets. After five days the blastocyst can be implanted into the uterus by a tentacle. By visualizing moving a set of structures into a cell the organs can recreate cells with the set. This creation of cells is stopped by visualizing the set separating from the cell. The generated cells emerge from the same tentacle that a blastocyst emerges from. A newly created naga knows only its own pluripotent set of structures and can see the set by thinking of itself. Its own pluripotent set does not include development information, new nagas must be created using a transform organ on another species. All other sets of structures must be taught to it. The organs do not give it the ability to know what a part of a structure does.
 Miscellaneous:
 A layer of fatty tissue insulates the belly of its lower body. Its feathers insulate its sides and back.
 The skin of its lower body is wrinkled on the sides and back to allow for expansion. The more it expands, the more it loses the insulation of its feathers, so large subjects must be taken in warm conditions.
 Its venom sacks are located behind the ribs of its false hips, giving the illusion of a butt. The ducts for the venom travel up its back, through its hood, down its sinus cavities to its hollow canines. Its venom is an anesthetic that paralyzes its prey and puts them into a deep restful sleep.
 For female mammalian prey the feeding parasite cells are sprayed over the cervix of the prey. Once the cervix is covered, cells continue to be deposited in the center. Tissue penetrates the cervical opening to a width of a couple of millimeters. After penetrating the cervix, the uterus is filled with tissue. The tissue simulates pregnancy to extract nutrients from the preys blood. The parasite grows to full size in a week. The parasite needs a hormone from the feeding tentacle or it will die within a month. The dead parasite will be passed out of the uterus like a stillbirth. A parasite is specific to a species and can be used on that species or any species that can act as a surrogate parent.
 A tissue generation organ is specific to an individual. The set of structures for a tissue generation organ is normally taught along with a sample tissue of the same individual. New tissue generation organs can be learned by learning the sample tissue of another individual and applying to the sample the difference between the original organ and the original sample. The tissue generation organ contains not only the information for generating the tissue, but also how to connect the tissue to the uterus wall and how long it will stay connected. This extra information deletes itself from the actual tissue that is generated.
 A transform organ is specific to a source species and a resultant species and may be specific to a gender of the source species if the gender DNA is to be changed. For mammals the transform organ develops an umbilical. The umbilical is placed onto the subjects belly button where it makes a hole and inserts two tentacles. The tentacles attach to the inferior vena cava and the hepatic portal vein to supply the subject with oxygen and nutrients. The tentacles are pre-filled with universal donor blood. Once connected the organ sends an anesthetic, to keep the subject unconscious during the transformation, and an immunosuppressant. Then the organ sends a virus like agent to change the subjects DNA. The new DNA causes bone marrow to eat away the bones to be changed and it alters, moves, and grows tissue where needed. Once the transformation is complete the organ stops sending immunosuppressant and begins to disconnect from the uterus. Once disconnected from the uterus the umbilical tentacles break off at the veins leaving behind a portion of tissue to suture the wounds. Then the umbilical breaks off at the skin, also leaving behind tissue to suture the wound.
 Milk production from its mammary glands is started consciously.
