The Garden of Unearthly Delights

Biodiversity in Glow Forest Communities

Down on the floor of the Glow Forest, a startling array of lifeforms has evolved in the cool dark mist. The creatures that comprise the main structure of this biome are known as Vela, and they stretch skyward, consuming all the available sunlight and allowing none to escape below. This species won an evolutionary arms race long ago, and as a result its photosynthetic competitors were pushed to extinction. However being a successful monoculture has its disadvantages. Autotrophs form the base of the food chain in most environments, and now the Vela is the only one. This means it is now the main food source for many other species who would otherwise have more choices. Its main nemesis is the Stragulum. This amorphous creeping wrinkled blanket infects a new Vela pseudopod nearly as soon as it touches the ground. It rapidly takes hold and covers every inch of the surface, slowly digesting it. This in turn attracts a cadre of new organisms which consume the flesh of the Stragulum. Predators are then drawn to the area, and as the number of species grows, a self-perpetuating cycle of increasing biodiversity takes place. Eventually, the Stragulum becomes too much of a burden to the Vela and it severs its pseudopod in order to rapidly grow another nearby. But the biomass of the parasite still lingers for quite some time, feeding a plethora of bizarre and unique organisms scrambling for their share of the resources in this oasis of light amidst the darkness.

Here is a nocturnal view of a habitat in which the inhabitants have evolved extreme forms of bioluminescence. The vertical glowing blobs are the reproductive bulb form of a species with a complex life cycle (to be elucidated in following artworks). The groove-backed, ravenous creatures at the bottom are of the same species as the glowing blobs, but at a different life stage. At center is a rather placid, slow-moving consumer of the bulbs- one who has incorporated its own form of bioluminescence into its respiratory apparatus as a means of camouflage. Names and descriptions will come as soon as possible.

This was a colored-pencil rendering of the creatures involved in the ecosystem portrayed in the "Aglow" piece. The pancake creatures on the floor are mobile decomposers. The floating lanterns are semi-autotrophic creatures that travel in groups. They travel by spouting air directionally through their vents which are visible along the middle of their bodies.

World Eater

In the murky ponds on the floor of the Glow Forest lives a surprisingly diverse community adapted to the near total darkness. Decaying organic material releases methane gas which is harnessed by towers of colonial microorganisms. Upon this bedrock of the food chain, a plethora of creatures creep and crawl about their daily lives while trying to avoid the pond’s top predator - a massive leviathan blindly devouring everything in its path.

High Above Saturn This portrait looking down on Saturn and its rings was created from images obtained by NASA’s Cassini spacecraft on Oct. 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected for shifts in the spacecraft perspective and still has some camera artifacts.The mosaic was created from 12 image footprints with red, blue and green filters from Cassini’s imaging science subsystem. Ugarkovic used full color sets for 11 of the footprints and red and blue images for one footprint.

Forest Floor

The long tendrils of the Purple Spire Creeper encircle this forest community deep in the valley. Following its traditional hunting path by the river, the predatory Veloxos has spotted its prey – a Dish-Faced Septaped that emerged from the undergrowth for a drink. The Septaped’s teal, reflective surface camouflages it well in its dimly-lit damp home on the forest floor, but now out in the open it appears as a shining beacon. After this brief instant of mutual acknowledgment, the race begins. The Veloxos’ three powerful hydraulic legs can propel it with surprising swiftness to get it within striking range of its harpoon-like proboscis, which extends almost instantaneously to the full length of its body. The Septaped is a formidable quarry. Though it possesses no defensive mechanisms, the seven muscular legs aligning its body can nearly teleport it back to its shady lair - where it will become lost in the shadows. The perpetual arms-race of natural selection continues daily all across the planet with countless moments such as this.

Grandulus

Trifasciatus grandulus

I should preface the description of this creature by giving a short statement about the natural history of its home planet. Early in its evolutionary history, life on this world did not split into such rigidly defined taxa as it did on Earth. For example, the majority of multicellular earth-life is divided into autotrophic creatures (plants) which are immobile, and the highly mobile heterotrophs (animals). On grandulus’s planet, the peculiar biochemistry allows for a much higher rate of horizontal gene transfer and endocytosis. This means that instead of a taxonomic “tree of life” like on Earth, their evolutionary history looks more like a web. In short, this allows for a wide array of photosynthetic, yet mobile creatures. The grandulus is one of these. It moves around slowly with its sticky appendages and positions itself in a spot with maximum sunlight to unfold its inflatable photosynthetic organ from its posterior shell. It also feeds on the internal fluids of metaflora, as well as decaying organic matter. Its many species range in size from that of a quarter to the size of a hippo.
