Krill (The Orville)

The Krill are an alien species that appear in The Orville, a TV series by Seth Macfarlane.

Physiology
They are pale skinned humanoids, with somewhat reptilian scales.

As a species that evolved in near-constant darkness, UV rays or other high light sources are deadly to The Krill, needing to wear armor head-to-toe in order to not die from sunburn in a earth-like enviroment.

As the show parodies Star Trek heavily, the look of the Krill bears some similarities to the Jem'Hadar from Star Trek: Deep Space Nine, and culturally, they have aspects of Klingon culture in that they are a warrior race and assured of their superiority, especially in combat.

Culture
The Krill are somewhat unsual for an advanced civilization in that they are highly religious. Said religion views non Krill as being without souls. Their holy book is called the Ankana, and worship a deity called Avis.
