Tholian

Table of Contents:




Members

  • Sexual monomorphic - hermaphrodites.

  • Individuals range from – 1.56 meters and 83kg to 1.73 meters and 100 kgs.

  • On average approximately same height but heavier than Humans.

Respiratory System

  • A series of spiracles in the exoskeleton.

Nervous and Execratory System

  • The basic Tholian nervous system plan consists of a series of body segments, each equipped with a pair of connected ganglia, with a paired nerve cord connecting adjacent ganglia in each segment.

  • The ganglia are bulbous structures consisting of neuron cell-bodies and supporting or glial cells and acts as a local processor or computer. Each ganglia are interconnected by neurons, constituting a computer network. The ganglia of the head segment form a fused mass corresponding to the head area and thus can be considered more or less the brain.

  • Tholians radiate unused heat and UV light through their carapace but also through specialized organs.

  • These organs can be used defensively and offensively to concentrate a ‘blast’ of radiation.

Digestive System

  • Tholians do not have a digestive system. They absorb heat and other forms of radiation primarily ultra violet (UV) directly through the carapace.

Visual System

  • Two eyes

  • The ‘eyes’ are actually more akin in function to the pit organ of various other organisms.

  • The eyes detect changes in the thermal radiation of the surroundings.

Circulatory System

  • Tholians are based off a completely different biochemistry. Instead of water, the basic solvent of the species is sulfuric acid. It has a very wide liquidity range (10 to 338°C). Though functions of metabolism would be best in the high temperatures. This reflects in the fact that Tholians environments are invariably hot but the creatures can function for a period of time in much lower temperatures.

  • H2SO4 works as acid and HSO4- as base.

  • The C=C double bond is used to store energy.

  • Due to absorbing radiation the need for a circulatory system is vastly reduced. Tholians thus use an open system in which the internal tissues are bathed in fluid that is moved by the movement of the organism supplemented with small pumping chambers in the various sections.

Skeletal System

  • Tholians use a silica based carapace exoskeleton.

  • There is a ‘head’ that hold the eyes and other sensing and communicating organs.

  • A main body from which two jointed arms ending in two jointed fingers.

  • The lower body is supported by six jointed legs also ending in two split toes arranged radially around the body allowing for quick movement in any direction.

Skin

  • None. External silicon based carapace.

Reproductive System and Reproduction

  • There is a specialized organ which functions like a ovipositor in which eggs and sperm are deposited between two individuals.

  • Tholians are hermaphroditic.

Back to Top



Endocrine System

  • Little is known.

Back to Top



Metabolism

  • Endothermic

  • Approximate body temperature 207 C.

  • Radation absorbed is transformed using a reverse Krebbs cycle.

Back to Top

Other

  • Tholians due to their generalized anatomy are extremely difficult to kill. The lack of centralized heart, respiratory system and neuronal organization makes the creature able to function even with massive amounts of damage.
