Alien landscapes.

On the planet, almost all plants are black. The exceptions are mushrooms and mosses, which have a range of colors from red to yellow and green.

If we imagine a timeline where placental mammals never evolved, it's easy to imagine marsupials filling many of the niches that placental mammals fill in our world. One could even imagine marsupial bat-equivalents or primate-equivalents, for example (a marsupial human analogue could be quite interesting!)

But I wonder if marsupials could've evolved into fully aquatic mammals, like cetaceans and manatees?

There would be some significant problems with a fully aquatic marsupial involving their life cycle. There are some semi-aquatic species of possum in South America that have pouches that can seal tightly to keep the joey dry when the mother is underwater, but for a fully aquatic marsupial, you wouldn't be able to just keep it sealed the whole time, or the joey would run out of oxygen. It would need to periodically open to let in fresh air, as well as for cleaning

Birth would also be an issue because the mother would need to make sure to stay on the surface long enough for the joey to crawl into the pouch (or ... could the birth canal actually move to open directly into the pouch, or the pouch move over the birth canal? Cetaceans were able to relocate their nostrils, so it might not be inconceivable that the birth canal could similarly be relocated)

Another issue would be that an aquatic marsupial would presumably have to remain close to the surface. If it dived too deeply, the pressure would collapse the pouch, which would surely be problematic for the joey, so even if they could become fully aquatic, it seems like they'd still be excluded from the deep-water environment that many whales have adapted to in our world

[Godpox] Angel biology I

Angels are multicelular, non-coelumates, exogenemorphous invertebrate colonial pseudokaryotes organisms, often referred to as Caelumzoa, Pseudozoa and Betazoa. Exogenomorphous - Non-earth living organisms that may appear morphologically similar to earth lifeforms but have completely different origins, xenobiological convergent evoluion with earth beings. Pseudokaryotes - "Cells" may have nuclei or not depending on circumstances. -> Neobacteria (You are here.) -> Amebagenes / Neoameba -> Proparaphorus

Neobacteria

Neobacteria refers to the supergroup of all bacteria-derived colonial organisms, bacteria that live within those colonies are called protooids, protooids are are also exogenomorphous, despite being identical to earth-bacteria except from their ability to become nucleated through fusion. Protooids cannot live outside of their colonies, the only circumstances a protooid will live outside of their body is by infecting another organism or by colonization. Uniphorus: Clade reffering to the species relying on a 'token' individual, token individuals are bacteria that specialize in producing necessary nutrients for the whole colony, uniphorous neobacteria are usually radial, non-molatile and are simpler beings. Uniphorus are single-multinucleated beings, meaning that the token individual is formed by fusion of other members, one individual will become the nuclei of the token, housing all the genetic material.

Pluriphorus: Clade referring to the Neobacteria that divide all of its individuals into different roles but with no specialized colony, pluriphorous bacteria are also radial but molatile and strategically move through the colony limits to ensure all members receive nutrients. Pluriphorous are multi-multinucleated beings, they may have one 'token' for each of their 'tips' and the center of their radius.

Eupluriphorus: Clade referring to the Neobacteria that divide its individuals into different roles which in turn will form specialized colonies, those specialized colonies will act as organs for the organism, eupluriphorus neobacteria are bilateral organisms and display higher complexity. Epluriphorus are "true pseudokaryotes" meaning than more than half of their protooids are nucleated.

An individual pertaining to a Neobacteria can be simply called 'bacteria', but the proper name is 'protooid'

Within those phylums, neobacteria are divided among which colony/specialization begins first, Eupluriphorus can be progastros (begin forming the food chamber first) or prodomus (begin forming structures in which the body will build itself upon). Progastros are rapid-growing protooids, often reaching maturity around 50 years of age while Prodomus are slower-growing, maturing at 150 years.

Eupluriphorus prodomical neobacteria: K'yebo-roo, (Neoneisseria gonorrheae) O'canungaçuga (Neocloristidium tetani) Eupluriphorus progastrical neobacteria: Q'wilqilth (Neomycobacteria leprae) O'bloodus (Neomycobacteria tuberculosis)

Colonial pseudoorgans

In progastrical neobacteria, a new individual is formed through gene leaking, eupluriphorus angels have gene sacs filled with nitrutious fluid. This fluid is often coloquially called as 'primordial soup', the primordial soup houses several pioneer protooids, pioneer protooids are the closest protooids to earth-bacteria, they however, carry large amounts of genetic information. During the relapse season, primordial soup becomes viscous and leaks out through the gene tubes, carrying with it great amount of pioneer protooids who are charged with creating a new Neobacteria from scratch using the sustainance of the primordial soup, only a fraction succeed this task. By year 5, these pioneers have already burned through their nutrient storage and wither, only the ones who have found ways to make their own food or were lucky enough to grow in fertile soil survive. 

In prodomical neobacteria, pioneer protooids begin as temporary autotrophs, analysis show that despite being a crucial skill to survive, as the population multiplies and mutates, all genes associated with autotrophic metabolism are lost. It's unknown what causes the starting colony to loose said genes, theories range from protooids finding more energetically sustainable to drain nutrients from outside sources to the autotrophic genes being plasmid-derived, protooids may find more advantageous to not rely in plasmids as it comes with a threat of radical genetical drift among members.

Pseudorgans or colonies are where specialized protooids reside, all protooids are polymorphous, meaning they can take several different shapes for their specific roles, colonies are lined externally and internally by specific protooids, some of them use pumps homologous to earth-derived bacteria efflux pumps whilst others may have increased wall permeability, there is enough space between pseudoorgans where fluid irrigates colonies with nutrients and other necessities.

more of the flat-nosed fishing cat! except its head actually looks flat this time. its smaller than a serval, but not by too much. litters are usually over one but still small, and kittens stay with their mothers for about a year. while flat-nosed fishing cats are solitary, theyre not especially aggressive or territorial towards each other, with ranges overlapping and little fights

da chroma. for halloween. 

they find out their spacesuits look like xenomorphs to people and, as a species that is basically smart deer (on the food chain), find this both flattering and hilarious

three of the species in my sci fi .. .spec evo spec world stuff balers are capable of shapechanging but i haven't included that yet, because there's numerous different little shapeshifting subtypes ghfjlghf

[wormwood-coast]

The elaborate mudclaw is a common inhabitant of tidepools along the Wormwood Coast. They are highly social creatures, communicating anything from fierce territorial displays to cooperative partnerships with the brightly-colored sails along their back. The claws between the primary pair of sails are not true jaws, but rather a mechanism for holding fast-moving prey in place while the mudclaw extends its radula from its underside to feed.
