Benzite

Benzites are a sapient, spacefaring humanoid species from the planet Benzar. They notably wear a breathing apparatus on their chests, with a tube extending up to emit vapors which they presumably need to inhale.

Biology
Benzites are hairless blue-skinned humanoids and easily recognized by their nasal lobes adorned with fish-style barbels. They also have pointed ears. Their hands possess five digits, but differ from those of most humanoids in that the fifth digit is an opposeable thumb much like the first one, making their hands symmetrical.

It has been noted that Benzites who come from the same "geostructure" naturally look similar, and appear to be in fact identical to a non-Benzite observer.

Culture and society
Benzites as a species are very eager to please and offer assistance, to the point that their behavior can easily be perceived as obnoxious.

Benzite ships protocols, as of 2365, differ from those employed by Starfleet. Specifically: a Benzite crew member who identifies a problem or threat is not expected to report to their commander until being able to come up with a full analysis and solution.

History
In 2364, a Benzite named Mordock became the first of his species to serve in Starfleet, perhaps suggesting that Benzar had recently joined the Federation at that point.

During the Dominion War, the Benzite home system was at one point invaded by the Dominion forces, but was liberated by the Romulans. Constable Odo wondered about whether the Romulans themselves would keep Benzar as a conquered territory after the war was over, but the answer to that remains unknown.
