The Andorians are a humanoid species from the moon Andoria, homeworld of the Andorian Empire, and one of the founding members of the United Federation of Planets.


Andorians employ characteristics of both mammalian and insectoid creatures. They have a normal internal skeleton with muscles attached to bones, but also have a limited exoskeleton, greatly increasing their strength. Andorian eyes are very limited in their abilities and are unable to discern color.

Most Andorians are blue-skinned with white or silver hair. An Andorian subspecies called the Aenar has white skin and, unlike blue Andorians, are blind and telepathic. Andorians and Aenar are genetically compatible and can produce offspring.

Andorians, with a higher metabolic rate than Humans, are susceptible to high temperatures: an Andorian can lose 10% of its weight within two days in climates near the boiling point of water. An aspect of their metabolism leaves them especially vulnerable to phase pistol fire; even minor phase injuries can prove fatal.

Since Andorian physiology makes intravenous injection impossible, physicians administer medication through intermuscular injection instead.

Andorians have two supercranial antennae that aid in balance. If one is lost—a humiliating experience—an Andorian becomes partially disabled in the short term, and unable to fight, but can adapt to its loss within a day. Antennae take up to nine months to regrow, though electrical stimulation and cranial massage therapy can cut regeneration time in half.

The twenty-second century Andorian Shran, reflecting on his own stub, demonstrated that antennae are moved by voluntary muscles that can be controlled separately from one another. Such movement can express feelings as well; Andorians can point their antennae at potential mates to signify attraction.

The placement of Andorian antennae has at least four different variations. Shran and others of the 22nd century sprouted antennae from their frontal skullbones. The classic ambassador Shras and his delegation sported antennae which sprung further back, off their parietal bones. Others have thinner antennae, or much longer ones.


Andorians are true bluebloods. Andorian tongues and gums alternate from dark blue to pink. Andorians have increased perfusion in colder environs and their metabolism is higher than that of Humans.


Andorians are a militaristic race, exemplified in small part by weaponry without stun settings. They consider it an honor to serve in their Imperial Guard, and military rank greatly influences social reputation. Deploring dishonesty—and never fighting without reason—Andorians are nonetheless capable of duplicity. They consider themselves deeply emotional, passionate, even violent; not known for their charity or sympathy, they place a high value on family. Imperial Guard members who die far from home can count on their companions to transport a body part back to the Andorian ices.

Culture and tradition

A crucial part of Andorian tradition is Ushaan, a code of honor demanding a duel to the death, with combatants pitted against one another using an ushaan-tor iceminer's tool. A vast body of regulations—up to 12,000 amendments—bind this code. Such a fight can be called off if one combatant disables the other enough to prevent its continuance. Though Ushaan can be called by someone to avenge a personal loss, there exists a right of substitution wherein each combatant can offer up a replacement; and married combatants can postpone duels indefinitely if they have no children to continue their claims.

Andorian weddings commonly require four people. Females enjoy an equal position in society, and as soldiers are as capable as males.

Andorians make prodigious artists. Handpainted Andorian tiles are well known throughout the Federation and Andoria's Academy is widely considered the best art school in the Federation.
