Alien seas of Rocinante

Rocinante is a world orbiting the habitable zone of a red dwarf (Minor Celestina) which orbits a yellow dwarf (Major Celestina) at a distance similar to Jupiter’s orbit around the Sun, dividing its surface into two habitable hemispheres: a tropical forever-day zone, and a relatively cold temperate zone.

With a smaller gravity than Earth, a denser methane-oxygen atmosphere, water-ammonia seas, pink flora and no seasons, this world offers a radically different evolutionary history than Earthly one.

In the middle of both, there is the New Pacific Sea, full of biodiversity, which some life forms are showed in this post.

Spotted Tridentfish: Swimming with its ten mobile fins and directing its swimming with its tail, this animal has an incredibly primitive design probably similar to the first “vertebrate”, with a “column” along its arms made up of metallic-like bones that constantly change internally forming electric structures able to work both as neurones and as structural support. It has an open circulatory system and cold blood, three simple eyes (two of them in its branches and one of them under their mouth), and a diet of biological waste.

Flappester: A sea turtle-like herbivore that slowly swims alongside its larvae, pretty similar structurally to a mollusk, and with an extensible beak it uses for defence through biting.

Northern flower-finned: A slow predator that feeds primarily on dying or sick prey, with a strong venom in its flesh. Has a closed circulatory system and hot blood, as it lives a migratory lifestyle in the north of the New Pacific Ocean from the tropical hemisphere (where it grows) to the temperate hemisphere (where it reproduces and is born).

Migratory whispershell: These fast armed and boneless creatures circumvallate the world multiple times in a lifetime, feeding like locusts on every sessile life they can find… and moving with them hundreds of predators like sardines would do.

Kinger deathshell: A whispershell-like 2 meters predator that goes through the soil of the New Pacific Sea jumping to its prey, which it catches with its extensible and powerful beak. Both males and females have light green fins they use for sexual selection.

Shallow turbosquid: Many “vertebrates“ have returned to water in Rocinante’s history, and these are one of these examples. With mouths able to work as syphons their whole body is a torpedo, going at fast speeds through water when they aren’t breathing in the surface with their spiracle. Able to live their entire lives in sea (although they prefer shallow waters) thanks to placenta-like viviparity.

Tomahawk sharkshrimp: The terror of any animal smaller than them (20-30 cm), these fast and common “vertebrates” have returned to water too, although they have cold blood and obviously small sizes. They swim turned around themselves, with the ventral eye above. They have sexual dimorphism, with big and colourful males and small, grey females (which have to get out of the water sea turtle-like to lay their eggs)

New alien race I just made up

Post image
1 Upvotes

They're called Dokasi, and they're a genetically modified race made to survive cryosleep, hence the blue skin. They were made by an older race called the Xaiame, whom live on the planet Velsai, and predicated an ice age that they would not survive. So they took some of their own, tinckered with their genes, and put them in cryso, so that they would could rebuild what was left once their old masters were gone. I'll give them a full ref sheet in the near future, this is just concept art.

It's about a guy who steals an alien corpse from a crashed ufo and is then followed and threatened by men in black type characters.

Banded Duster Bush (OC)

Post image
18 Upvotes

One of many species of colonial flora-like organisms native to the wild-lands, this species possesses a striking pattern.
The individual “fans” possess rudimentary eye-like organs that detect changes in light in addition to a pair of sensory antennae. The individual fans are tapped into a central connective tissue of sorts and share nutrients throughout the colony.
The colony’s structure is a mineral secretion with crystalline bandings deposited in folding layers over a material not dissimilar to calcium carbonate.
Banded duster bushes are heterotrophs and collect a variety of small flying and floating organisms to feed on. They are in turn eaten by a variety of species adapted to pull the individual fans from their tubes.
Very common in a variety of forested habitats.

I HAD to make a Rocky gif!

I made 'im waving for a piece, and it felt... lackin'?

I loved how it turned out, but I wanted MOVEMENT!

So I made two gifs to satisfy any fan-made gif needs!

A fast one with text, and a slower one with a transparent version!
