Editing Andorian (section)

=== Physiology ===

Most Andorians had a distinctive blue skin and white or silver-colored hair. Andorians had a higher metabolism than humans and also slightly stronger. Andorians were very susceptible to high temperatures, an Andorian could lose 10% of its body weight in as little as two days in climates approaching the boiling point of water. Because of the unusual physiology of the Andorians, intravenous injection was impossible; instead a doctor must opt for inter-muscular injection.

Andorians had on their heads two knobbed antennae which were used for balance. An Andorian was partially disabled and unable to fight immediately following the loss of an antenna, but was able to compensate this within a day or so. The antenna itself could take up to nine months to regrow on its own, although the regeneration could be completed in around half that time with electrical stimulation and cranial massage therapy. The loss of an antenna was a humiliating experience for an Andorian to come to terms with. Antenna movement apparently expressed feelings as well. An Andorian would sometimes point their antennae at a potential mate to signify attraction.
