Species

For all species that appear in The Orville:

Minor Species
Name	Episode Appearance
Janisi	Episode 2x05: All the World is Birthday Cake (mentioned only)

Keribex	Episode 2x01: Ja'loja (mentioned only)
A species distinguished in that they have two heads. John LaMarr once dated both heads of a Keribex for about two months in 2419, with neither head finding out about the other one. Ultimately, however, LaMarr ended the relationship as the left head always wanted to go hiking, which was "sort of a deal-breaker" for him.

Olix's species is an official member of the Planetary Union.^[1] These people are reptilian humanoids with two horns, a thick protective skin, and two elongated nasal cavities.
