Trissir

Trissirs are a spacefaring race hailing from the former planet Examina. When their home planet was destroyed trissirs hurriedly fled, scattering across space. Eventually these refugees came together and formed federations, the Triumvirate being the largest by far.

Appearence
Trissirs are bipedal hexapods. They are tall and lean, with a tail roughly half the size of the rest of their body. They have four arms; the upper pair is longer and stronger, while the lower pair is smaller and frail. They are completely hairless, with soft and velvety octopus-like skin. Though they have mostly a dark blue complexion, their skin can range from many shades of blue to dark purple and even a light cyan. They are digitigrades, walking with their toes touching the ground while the rest of the foot is lifted. They have oblong-shaped heads with three eyes.

Physiology
Trissirs grow at a fast rate, and become sexually mature only 5 years after birth. Trissirs are simultaneous hermaphrodites, producing both male and female gametes at the same time and are able to self-fertilize. Fertilization occurs externally, by releasing the buoyant eggs and sperm into a body of water.

Though slim, their bodies have high amounts of brown fat distributed throughout, in addition to producing an antifreeze protein, adaptations that let them function at low temperatures.

The trissir circulatory system makes use of the protein hemocyanin to transport oxygen through the body. It is found free floating, suspended directly in the blood plasma, as opposed to hemoglobin which is confined within red blood cells. The hemocyanin makes their blood a light blue color when oxygenated and colorless when deoxygenated.

Life Cycle
The trissir life cycle can be described as an alternation of generations, a type of life cycle that occurs in earth plants in which each generation alternates between haploid (having one copy of chromosomes) and diploid (with two copies of each chromosome, like humans).

A sporophyte (a diploid individual) grows, and, when ready, reproduces through a haploid cell created through meiosis, called a spore. This spore is similar to a gamete but grows on its own, without fusing. Once it lands somewhere it grows into a haploid organism.

This haploid organism is called a gametophyte. The gametophyte grows and when mature produces gametes through regular cell division (it already has a single set of chromosomes). When fused, these gametes turn into a zygote, which grows into a sporophyte, and the cycle begins again.

Psychology
Trissir are less susceptible to boredom and show less reactive aggression when compared to humans. They have a psychological need to feel productive and useful, not dissimilar to other species' need for socialization and fun. A trissir will do a monotonous, repetitive task on a strict schedule with no discomfort. They also have a high tolerance to pain.

Culture
Trissir culture values practicality, looking at the bigger picture and a pragmatic approach to situations.

Trissir first names are given based on current occupation. When a trissir changes position their name changes accordingly. Surnames are used to keep track of family relations.

Old Empire
The Old Empire is the predecessor to the interstellar trissir Empire. Though destroyed alongside Examina, most of the survivors who fled into space were from the Old Empire.

Triumvirate
The Trissir Triumvirate came to be long after the fall of the trissir home planet. The Triumvirate colonizes worlds not for living space, but for their resources; preferring instead to use spacecrafts and mega structures for housing.

Its capital is Neoxaminis, a mobile dwarf-planet sized mega structure.

Lifestyle
Trissir live in designated living quarters inside the mega structures and spacecrafts in which they work. Those that live in settlemeining colonies live either in individual housing units or apartment complexes.
