Axanar

The Axanar are a space-faring humanoid species and one of the first sapient races encountered by Humans. The Axanar hail from a planet also known as Axanar.

Biology
They are notable for having cranial ridges, green blood and a so-called zymuth gland which secretes a substance known as triglobulin, which is used by other races due to its medical and aphrodisiac properties. It is worth noting that this substance is said to be fairly similar to Human lymphatic fluids. They have a lifespan of 400 years (whether these are Axanar years or Earth years is still unclear) and are androgynous.

History
In 2151, the Axanar made first contact with Humans via Enterprise NX-01.
