Life on Eile

Eilen(anything that is native to Eile) life is carbon-based, and use water as a medium, requiring elements like hydrogen, sulphur, oxygen, nitrogen and phosphorus being organised. We are going to over the main groups of life that is on Eile.

The major domains of life on Eile

Domain Propogatorae: This is a domain of self-replicating simple proteins that seem to be most abundant at rich volcanic slews of the Volcanic habitats.Too simple to be life yet too complex to be a molecule.

Domain Euvira: These are Eile's domain of true "viruses" and are most akin to them, which are basically pieces of DNA in protein coats trying to parasitise on organic cells.

Domain Nanoa: Simplest beings which are complex enough to be counted as Organisms on Eile, they often are more akin in complex to the simplest prokaryotes on Earth, maybe a domain of complex proteins who try to be "prokaryote" analogues but at the same time require symbiotic relationship to live would be a role more fitting to these peculiar organisms. 

Domain Paliokaryota: Eile's most ancient and poorly understood domain of life. Most organisms are unicellular and inhabit similiar niches as unicellular organisms do on Earth. However, a poorly understood clade, known as the Igolids( igol;igolka;spike/needle ) previously thought to belong to the Korenids(closest thing to "plant" analogues on Eile) have been analyzed to belong to this domain of life, effectively reclassifying as the most isolated group of multicellular life to exist on Eile.

Throughout the cold beaches of the isolated Ruka Macro-Peninsula, part of the great Voreios Polar continent on Eile, one can see the Pinasora solus EILE "Lonely coastpine EILE", on the upper areas of the beach. Using xanthophyll pigments, tough "hide" and a strong internal structure connecting the roots, these small organisms are unique producers that dominate the niche present. These organisms are part of the Igolids. 

Domain Anapnoikaryota : The Anapnoikaryotes are the Eukaryote analogues, they possess a Nuclearate(Nucleus analogue) and an anapnoiate ( Mitochondria analogue), which differ in almost nothing. Anapnoikaryotes were able to achieve multicellularity just as with our Eukaryotes with Anapnoikaryotes developing into several multicellular and unicellular kingdoms.

Major/relevant kingdoms of Anapnoikaryote life 

Kingdom Photoida/Korenida : These are the true "plants" of Eile, a specimen/specimens of the kingdom Korenida are called Photoids/Korenids, the korenids taking the niche of primary producers of the planet,being autotrophic sessile organisms, capable of making their own food through photosynthesis, hence the name photosessilida. Being detectable from space itself by their green colouration and sometimes red in tundra habitats, having a wider range of photosynthetic pigments, including xanthophyll, a brownish yellow. They are found in aquatic habitats to denseforest habitats to the coldest of the pole habitats and have a wider range of photosynthetic pigments , though, most tend to use chlorophyll pigments, especially in the more hospitable regions of Eile. Photoids can be found in every nook, cranny and fold on the surface of Eile. Photoids are exclusively multicellular. They are able to use root-esque structures, branched holdfast structures , or hyphae-like structures to root themselves in place.

Kingdom Heteroida/Anapneteroida: This kingdom is exclusively sessile heterotrophs, which use a variety of ways to get their energy, they also are found in both terrestrial and aquatic habitats. They seem to be a strange mixture of possessing features which are akin to fungi,and features which are akin to animals. Some clades have the ability to filter feed using basic digestive systems underwater.Some clades are able to take the niche of decomposers on land and feed on exohummus and decaying matter via mycelium-like threads, plus conducting symbiotic/parasitic relationships with other organisms. Heteroids usually reproduce asexually. 

Heteroids and Anapnoils have a blurry line in terms of classification when it comes to aquatic heteroids and some sessile anapnoizoans, including poroidians which have a very, very close genetic relationship with heteroids, including sharing basal ancestral "parent" genetic information, and look very similiar. A lot of these sessile anapnoizoans then share basal genetic information with the typical motile "animals"/anapnoils.

It is therefore, widely agreed upon that Anapnoizoa is a derived kingdom, with somewhere in some derived metazoan-like anapneteroid clade began using a "motile" stage to spread more effectively. 

Kingdom Anapnoizoa: The metazoan analogue on Eile, they are the higher organisms of Eile, a member of the Anapnoizoa is called an Anapnoil. Anapnoils are the highest organisms on Eile, with the most complex systems and structures known on Eile. They are found from Aquatic habitats to polar habitats, having unique adaptations and specialisations in many areas.

 

Cladogram of the relevant phylums in the kingdom of Anapnoizoa

Articulusida: These are unique organisms, evolving motile joints from armoured chitinous segments . These evolved from slug-like creatures. Mainly microfaunal and possess cartiliginous mesoskeletons, in contrast possessing flesh similiar in structure to earthen molluscs .

Eumollisida/Carnesformae : The eumollisids are true "mollusc analogues", however, some clades possess segmented internal shells which help them to get larger than earthen molluscs, even developing a sort of iron pseudo-skeleton in some specialised, more higher and evolved clades. Strange clades of aquatic "pseudo-snakes" and "pseudo-eels" belong to this phylum, having a iron-infused skeletal structure and assuming predator niches. Despite this evolution, they are still mainly micro-faunal and part of the larger inapothemaite super-phylum on Eile. In a peculiar manner, some have de-evolved into worm-like forms in this phylum.

Poroida: An exclusively aquatic phylum of mainly sessile sponge-like creatures which are poorly understood. They take the niches of sessile filter feeders in the aquatic habitats, most interestingly, there are also specialised clades of sessile poroids widespread in freshwater habitats. Their name comes from the fact many of the are porous/ use porous appendages to gain food in the ocean. Some classes however have become mobile, albeit microscopic, perhaps descending from microscopic poroids that decided to stay microscopic and motile. In this phylum, heteroida/poroid classification becomes extremely, extremely fuzzy.

Gelataida: This phylum is made up of transparent and sometimes opaque organisms, characterized by their "gelatinous" appearance. It is the only phylum that contains "composite anapnoils", groups of gelataids from different clades evolving to be part of a larger organisms at some point of their lives, which assume certain niches. 

Eubrachida: A mainly worm-like phylum quite important to many ecosystems of Eile , being decomposers, parasites, and filter feeders. 

Apothemaasvestiouida: This super-phylum is made of organisms who have evolved to have some form of calcium/ hydroxyapatite+ collagen bone in their body. A member of this phylum is called an apothemaite.

There are two supraforms of apothemaites,that are classified based on shared physiology and appearance rather than relations, the first is euchordate apothemaites, of those who look closer to "vertebrates" on Earth. Euchordate apothemaites deserve their own future dedicated post explaining what are they and how they function, But briefly;

Appendixaforma; This phylum has the basal traits of having appendages for various sensory functions, including antennae for hearing, smelling. 

Dyopoda; This phylum has two limbs that function as legs (or fins depending on the habitat) as it's basal traits along with a peculiar internal support structure. 

Caputicentralisida; This phylum retains a peculiar centralised system in an enlarged encaphalon that at times fuses with the rest of it's body, as a basal traits, and needing appendages which consume and crush food.

 These include the sub-phylums of caputicentralisida, the appendixaforma, and the dyopoda. Second are parachordate apothemaites, which are the Quadrachordata and Apotheamischosita. 

Quadrachordata;  "Echinodermesque" clade that evolved in a variety of habitats, each possesses inherited radial to bilateral symmetry and the four "spino-chords". They have evolved in various shapes.

Apotheamischosita; Mainly sessile organisms akin to tunicates or sponges on earth.
