Background information

The name of Arex's homeworld originated in a non-canon catalog published by Lincoln Enterprises in 1974, which included biographies of Arex and M'Ress. The Edosians were described as a peaceful, long-lived species worshiping many gods. Though the Animated Series may suggest that the Edosians are Federation members, the Lincoln biography claims they are merely in "loose alliance." Despite the information from the biography not being canon, the name of the planet seems to have been accepted in canon, and StarTrek.com uses information from it.

Knowledge of the Edosian suckerfish among Humans, as mentioned in "These Are the Voyages...", suggests first contact with Earth, or affiliated species, at a date prior to 2161.

Apocrypha

Both Arex and M'Ress appeared in the DC Comics Star Trek title starting with issue #37 of Volume 1, both having been assigned to the USS Enterprise-A.

Arex also appeared in Star Trek Omnibus: The Original Series in the issues Star Trek: Year Four and Star Trek: Year Four - The Enterprise Experiment.

In the Star Trek: Titan novels, Lieutenant Kershu, an Edosian female, serves as a nurse aboard the USS Titan.
