Mira is hot E-planet in Mirabilis system, 35.40 Mly away from Earth in Sombrero galaxy. It is the fifth planet of the system, discovered by humans in 12348 AD. Despite its extreme conditions it harbors a lot of complex organic life, even sentient life like Venaliri.

The name Mira (amazing in Latin) was given by human exobiologist Jon Serafim beacause his team studies show that Mira's native is organic life and not silicon-based erroneous believed before any studies.
Atmosphere and climate
Mira have an thick atmosphere with an average density of 332. 36 kg/m^3 and a atmospheric pressure of 320 atm. It weights 0.00067359 M⊕ and have a average molecular mass of 42.103 and a height of 21.92 km. Because of thickness of atmosphere, the ring system is barely visible on Mira surface despite being quite large. Miran atmosphere is composed of 84.7 % CO2,13.8 % O2,1.19 % H2O, 0.291 % SO2 and traces of N2,He,Ar,Ne. Speed of sound on Mira is 360.79 m/sec. Seasons on Mira do not exist. Dayside have large mountain chains giving a maximum surface temperature of 123.89°C. The temperatures on nightside can get so low as -220.32°C. Mira have a runaway greenhouse effect of 216.18°C.
Life on Mira exist in terminator zone and temperate zones of nightside.
2000 species of photosyntetic black algae form the basis of terrestrial food chains in terminator zone. The miran equivalent of forests are symbotic structures known as ardirs between black algae and huge sphere-like covered in transparent chitin animals. The seas,rivers and lakes harbor photosyntetic and chemosyntetic lichen-like vegetation known as peldors. The basis of food chains on nightside are jiunes, fruit-bearing fungi.
Piktodoids are gelatinous animals divided in Stryps, Ukreghs and Kinnauls.
Stryps are aquatic and terrestrial gelatinous squid-like animals. Depending on species they could have between 6-20 tentacles. Their colors range form white,yellow,black and blue. There are 12000 different herbivore,carnivore and omnivore species. Each tentacle has a mouth.
Ukreghs are terrestrial gelatinous slug-like animals. They have from 4 to 8 pairs of antennae used to sense smell and sound. They care for their young, but some species are brood parasites like Earth cuckoo birds. There are 6000 species
Kinnauls are 7890 species of flying gelatinous creatures. They resemble jellyfishes, but more aerodynamic having 2-6 wings. Some species are capable of producing and manipulating electricity.
Verbnals are animals covered in chitin.
Xeocfs are worm-like chitin-covered animals. There can live in water or in surface. Many are active predatory species.
Seesids are animal part of ardirs. Because they take food from black algae, they have no mouth, but tube-like structures which are burried to provide water and nutrients to black algae.
Gretzul are miran equivalent of earth vertebrates. Their bone structure is formed primary by different cristaline forms of Al2O3. Because of this, humans refer to them as sapphire and ruby boned. They can divided into Quonars,Tirsomas,Dirdonites and Alethors.
Quonars are aquatic creatures resembling earth stingrays and deep sea fishes. They are the most diverse class of animals on Mira, composed of 100,000 species and the most numerous,occupying different ecological niches. They are clasified in blue-boned, pink-boned,green-boned and purple-boned ones.
Tirsomas are amphibian and terrestrial animals. They have evolved from blue-boned Quonars which have ventured on Mira surface. They have six limbs.
Dirdonites are a class of flying creatures evolved from a now extinct family of Tirsomas. They are roughly miran equivalent to Earth birds. They have hollow bones and 4 wings. Females stores their eggs in a eternal organ know as kilon. After males fertilize the eggs, the females are hatching them inside them. Both parents cares for their youngsters.
Alethors are a class of 5000 terrestrial species evolved from a now extinct family of Tirsomas. They are viviparous, giving birth to life infants and taking care of them. The infants are feed by their mothers with loraxoze, a honey-like substance produced by a gland in the mouth.
Venaliri are an early space-faring species which managed to colonize there 3 star system. They are Alethors.
