Lurian
The Lurians were a humanoid species native to the planet Luria. In the 24th century, they were rarely seen outside of the Ionite Nebula region. ()

Physiology and culture 
The average Lurian stood approximately two meters tall, but had a much broader and heavier body. Lurians were grayish- or tan-skinned. Their most noteworthy feature was their narrow, elongated heads. They had wide mouths, puggish noses, and small, deep-set eyes. (, et al.)

According to Odo, Morn is androgynous. () However, this might have been a jest since Morn was since only referred to as a male.

Lurians were known to have multiple hearts, () four lungs at the minimum, () and two stomachs. As a result, they were not only more resistant to damage than most species, but were also able to withstand poisons and other toxins much better. They were able to store liquids in their second stomach for many years, if necessary. ()

At least some Lurians preferred to sleep in a "hot tub" of mud. ()

One Lurian custom was to bring gifts of food and drink for the deceased so that they would have something to sustain them in the afterlife. ()

History 
In the 24th century, the Lurian government was controlled by the Royal Family of Luria. ()

After the Burn in the mid-31st century, Lurians were present in both Starfleet and the Emerald Chain. ()

Background information 

The species name "Lurian" was thought up by Mark Gehred-O'Connell and made its canon debut in "Who Mourns for Morn?". Gehred-O'Connell was permitted to name the species (and invent the idea of them having two stomachs) even though he was a freelance writer. ()

The name of the species was first used in behind-the-scenes reference sources, such as Cinefantastique (1993, Vol. 23, No. pp. 18 & 40) and The Making of Star Trek: Deep Space Nine (1994, pp. 2 & 17).

Designing the facial appearance of a Lurian began with a sketch which Makeup Supervisor Michael Westmore illustrated on the back of a script, labeling the image simply "alien". (The Making of Star Trek: Deep Space Nine, p. 2) Westmore later likened the Lurian facial design to that of a bulldog. (The Official Star Trek: Deep Space Nine Magazine issue 1, p. 28)

It took multiple tries to perfect the Lurian appearance before one particular look was settled on. As such, several heads were made for Morn to appear in . "[They] have not been seen since," laughed Michael Westmore. "That's because some of the heads they [the DS9 producers] felt were a little too far out, that they weren't quite Star Trek." () Ultimately, Morn's prosthetic head was sculpted by Vincent Niebla,  who won an Emmy for his work at only twenty-one years of age. 

According to Michael Westmore, the mouth part of the Lurian headpiece was designed so as to allow the actor playing him to speak, should the need arise. However, no Lurian ever spoke a single word on . ("Michael Westmore's Aliens: Season Four", DS9 Season 4 DVD special features)

StarTrek.com identified Valentine from  as a Lurian, although his make up appeared to be Betelgeusian. 

Though Morn was stated to have gone bald as a result of storing Latinum in his stomach, every other Lurian shown on screen is depicted as being similarly bald.
