Alien Classification System

[Knight26]

Ok, since all my projects are wrapped up while I wait for my transfer at work I have had a lot of time on my hands. So recently I have been putting together an alien classification system, yes that bored. I am trying to keep it simple yet keep all the most pertinent information on it. Basically this would be something that goes on an ID card or description sheet when, especially when picture is not available and would give key information on a species. So far I have the following parameters, what other parameters do you think would be needed:

Species name

Base element (the building block element; carbon, silicon, etc...)

Metabolizing Element (the element needed for survival, in the case of humans, Oxygen)

Breathing medium (gas, liquid, amphib, etc...)

Gen Type (mammal, insectoid, homonid, etc...)

Sensory organs (does it have eyes, ears, nose, etc...)

# eyes (if any)

visible spectrum

# limbs

# prehensile limbs (how many can manipulate objects) (not necessarily the number of hands)

# sexes

size (overall height or length)

Lifespan (typical)

Amino Acid Direction (help ID food that would otherwise be poisonous)

Activity level (what is their activity level in galactic society)

Special Info (anything not already listed)

Distinguishing features (any physical features of note)

So what would you add or subtract from that list? A lazy example from book for terrans would be:

Terran:Carbon-Oxygen-Gas-Homonid-AVOTG (Audio, Visual, Olfactory, Tactile, Gustation [taste])-2eyes-White spectrum-4 limbs-2 prehensile-2 sexes-size 3 (5-7ft)-life span 2 (100-150 years)-Left Amino Acid-Active in Galactic Affairs

Coded as: C-O-G-H-AVOTG-2-W-4-2-2-3-2-L-A

Tendencies towards other species maybe, and organizational structure.
