There is a alien species known as the Titanians.
The Titanians are organic biologically, but of a alien biochemistry much more cryophilic and oily. They drink ethane, breathe oxygen (you can have oxygen in a environment like Titan- Oxygen doesn't condense too much at those temperatures) and eat other Titanian fauna. The Titanians bleed a reddish, oily substance, as they drink hydrocarbons and I figure the reddishness may come from tholins.
The Titanians generally enjoy a temperature of around 90-140 Kelvin.
Chemically they're made from Nitrogen, Carbon, Ethane, Sulfur, Hydrogen, Acetylene and have plastic bones. Much like with us they have bones that are harder to break than the 'meat'. Overall their biochemistry is very oily.
One of them is to exposed to the sun of a Cuban beach without protection.
This Titanian has no unique properties, it's human sized and has no special resistances. It's an average Titanian.
What happen to this poor Titanian if it was:
- Splashed with water
- Exposed to the heat
- Touched by a human or stabbed by one (in the latter case- do they bleed or does their blood boil away?)
As a bonus question, would there be a difference if the Titanian was radiation resistant or would the results be the same?
I ask since I am not really certain how to predict any of this.
