The Osnullus were a sentient species. By the late 2250s, members of this species were serving in Starfleet. (DIS: "The Butcher's Knife Cares Not for the Lamb's Cry")


They had large non-humanoid heads with no mouth, with otherwise humanoid bodies. They had six eyes, two large and four small. An individual's skin color could vary, including pink and purple. (DIS: "Point of Light")


Several members of this species served on the USS Discovery in 2257. (DIS: "The Red Angel")

In the 32nd century, members of this species served in the Emerald Chain security force on Hima as well as in Starfleet. (DIS: "That Hope Is You, Part 1", "Scavengers")

In 3190, Osnullus delegates were present at the Multilateral DMA Strategy Assembly and voted for diplomacy with Unknown Species 10-C. (DIS: "...But to Connect")




Background information

Symbol and name

The name of the species was not spoken on screen, but was seen on a delegate's voting holo and a voting tally in DIS: "...But to Connect". A close-up of the tally was later released by graphic designer Timothy Peel. [1] Prior to "...But to Connect", the name was known from background sources.

Glenn Hetrick, Department Head of Prosthetic and Special F/X Makeup for Star Trek: Discovery, used the term "Osnullus" on the Alchemy Studios website. The website features images of the head sculpt and hand sculpt of this species. [2] The species had also been referred to as "Osnullus" by other production sources such as actress Avaah Blackwell and director/executive producer Olatunde Osunsanmi. [3] [4]

Osnullus is a broken-Latin formation intended to express "mouthless", from Latin noun os, oris (mouth) + pronoun nullus (none).


According to the Star Trek: Discovery Campaign Guide, Osnullus eat through specialized feeding ports in their fingers due to their lack of mouth. They have a caste-based society.
