Star Trek: 10 Things You Didn’t Know About Andorians
6. They're Literal Blue Bloods And Have A Fast Metabolism
"Blue blood" is a human metaphor for nobility. However, as depicted in the Star Trek: Enterprise episode The Aenar, Andorian blood is non-viscous, translucent, and literally blue. The Andorians also have better perfusion, or delivery of blood to the capillaries, in cold environments.
Andorians are known for their physical endurance in hand-to-hand combat but they have a faster metabolism than humans. Theoretically, this means that if a human and an Andorian stepped outside for fisticuffs, the human could defeat their Andorian opponent simply by exhausting them. This also means that Andorians are more vulnerable to phase-pulse infections, meaning that if an Andorian gets shot by a phaser, they are more likely to die from wounds than a human would survive.
Andorians can also survive a wide range of severe environmental conditions. As depicted in the Star Trek: Enterprise episode The Aenar, Andorians are highly heat resistant. They can even thrive in conditions with temperatures near the boiling point of water in spite of losing up 10 percent of their body weight in two days.
According to physiologist Zach Schlader from Indiana University Bloomington, humans would tap out and find someplace to cool off around 35 degrees Celsius or 95 degrees Fahrenheit.
