Nacha 1

Nacha are small tauric arachnids.
Nacha have humanoid upper bodies and spider-like lower bodies.
Nacha upper bodies are covered in flexible, skin-like exoskeleton.
This flexible exoskeleton is dark brown.
Nacha lower bodies are covered in rigid, armor-like exoskeleton.
This rigid exoskeleton is dull red and covered in fluffy white fur.
Nacha have 2 arms on their upper bodies and 2 pedipalps and 8 legs on their lower bodies.
Nacha arms, pedipalps, and legs are covered in rigid exoskeleton and fur.
Nacha arms end in 3 dull red claws.
Nacha pedipalps end in dull red retractable, venomous fangs.
Nacha legs end in 2 hoof-like, dull red claws.
Nacha have horns and can produce silk from spinnerets.

The nacha upper body consists of a head and a torso.
The nacha head contains a brain, 2 eyes, 2 ears, a mouth, a nose, and 2 horns.
The nacha brain is surrounded by a protective endoskeletal skull.
The nacha eyes, ears, mouth, and nose mostly resemble their human counterparts.
Nacha eyes are yellow.
Nacha eyes have nictitating membranes for protection from dust and sand.
Nacha eyes have tapetum lucidae for improved night vision.
Nacha ears are pointed and can be moved freely.
Nacha teeth are sharp, white exoskeletal projections anchored to the jaw.
Nacha horns are straight, dull red exoskeletal projections anchored to the skull just above the ears.
Nacha have fluffy white hair.

The nacha torso is attached to the head with an endoskeletal spine.
The nacha torso contains the pseudo-lungs and the anterior stomach.
The nacha pseudo-lungs are surrounded by protective endoskeletal ribs attached to the spine.
The nacha anterior stomach is below the pseudo-lungs.
Nacha arms are indirectly attached to an endoskeletal shoulder girdle with muscle.
Nacha pedipalps are indirectly attached to an endoskeletal pelvic girdle with muscle.
Nacha fangs can fold up out of the way under the pedipalps.

The nacha lower body consists of a thorax and an abdomen.
The nacha thorax is attached to the torso through the endoskeletal spine.
The nacha spine fuses to the bottom of the thorax exoskeleton.
The nacha thorax contains the sub-brain.
The nacha sub-brain extends out into the roots of the pedipalps and legs.
Nacha legs are directly attached to the thorax exoskeleton.
Nacha legs attach radially behind the pedipalps.

The nacha abdomen is attached to the thorax with an exoskeletal pedicel.
The nacha abdomen contains the heart, posterior stomach, ovaries, and spinnerets.
The nacha heart stretches along the inside of the top of the abdomen.
The nacha posterior stomach stretches below the heart.
The nacha posterior stomach and ovaries exit the abdomen at the cloaca.
The nacha cloaca is below and just before the tip of the abdomen.
Nacha have 2 spinnerets attached to the tip of the abdomen.
Nacha spinnerets extend out a short distance.

The nacha digestive system consists of the mouth, 2 stomachs, and the cloaca.
The nacha anterior stomach stores digestive fluids produced in the posterior stomach.
Food in the nacha anterior stomach is digested and pumped to the posterior stomach.
Food that can’t be digested is regurgitated.
The nacha posterior stomach absorbs nutrients from digested food.
Food waste is excreted.

The nacha circulatory system consists of the heart, 2 aortas, countless arteries, and the body cavity.
The nacha heart is a simple muscular tube connected to an aorta at each end.
The nacha heart has small openings along the sides connected to the body cavity.
The nacha heart draws in blood through the small openings.
The nacha heart pumps blood out both aortas.
The anterior aorta travels through the pedicel to the thorax befor branching out into arteries.
The posterior aorta branches out into arteries almost immediately.
The arteries carry blood into the nacha body cavity where it is needed.
Blood flows back to the nacha heart through the body cavity.

The nacha respiratory system consists of 2 pseudo-lungs and countless tracheae and tracheoles.
The nacha pseudo-lungs pump air from the mouth into the tracheae and back.
The tracheae travel up into the head and back across the pedicel into the abdomen.
The tracheae branch out into smaller tracheoles, which carry air where it is needed
Oxygen travels from the tracheoles into the blood and then into the organs and muscles.
Carbon dioxide travels back through the blood into the tracheoles, tracheae, pseudo-lungs, and out the mouth.

The nacha nervous system consists of a brain, a sub-brain, and a spinal cord.
The nacha brain is responsible for sensory processing, upper body movement, and higher brain functions.
The nacha sub-brain is responsible for lower body movement and automatic vital functions.
The extension of the nacha sub-brain into the pedipalps and legs allows for semi-autonomous movement.
The nacha spinal cord connects the brain and sub-brain.
The nacha spinal cord extends past the sub-brain through the pedicel into the abdomen.
