| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web. While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself!

Okay good time frames. I would like to submit an idea for a group of animals. I would like to introduce the idea of an inbetween group that is inbetween Gastropods and Cephalopods. They have 2 muscular feet like those of Snails witch they crawl on and have a strait shell. They also have 2 eyes on stalks and 6 tentacles in front of the body. They have a radula inside of their beaks which are made of the same material as their shells exept in parts that bend. What do you think? |

How about haveing stuff like the garden worms in the FIW as the land "plant"? |

I'm not sure garden worms could replace plants. Garden worms lived in a sparse environment, were small in numbers and the algae growing on them would not be nearly enough to support a large amount of animals on land. |

I wish I could give the public a true picture of the queen as she appeared at her best, but this would be impossible, even had she permitted a photograph to be taken, for her charming play of expression while in conversation, the character and intellect which were then revealed, were only half seen when the face was in repose. -Lilias Underwood when speaking of Empress Myeongseong "I was born in the dark.

We must take action, your Majesty, without hesitation, to further modernize this still ancient kingdom."-Min Young-ik to Empress Myeongseong | |

Maybe they could become more advanced than the garden worms? If they are Echinoderms like a Sea Cucomber they might develope a supportive notochord which would allow them to grow bigger. And the Algae may evolve into more advanced multicellular symbionts that grow from the creatures, like Plants that take the form of singular leaves? The Plants only need nutrients from the animal while the animal gets a sugar fueled Metabolism. |

But what do these animals survive off of? Algae that grows on animals would not be able to produce enough oxygen to sustain thousands of animals. No matter how large or complex there would not be enough animals for the algae to live off of and produce the necessary amount of oxygen to keep these animals alive. |

Maybe most of the Oxygen is made in the water and the land flora makes very little? |

Somewhat mobile plants might be interesting as well. The Ediacaran was before the emergence of 'land plants' so I could see mobile, photosynthesizing organisms evolving to macroscopic size (perhaps a 'colonial' organism in the same way a Portuguese man-of-war is) having a chance to compete. I do not think they would survive past the Carboniferous-equivalent, as plants expanded: though some might hang on in some remote place, like stromatolites in Australia. Another animal phylum idea: Lucifervermes. (Devil-Worms, Spikestars): These strange creatures are derived from a relatively undistinguished wormlike ancestor. However, they began to develop hard plates in their skin as predators evolved. As this armor grew larger and began to nearly enclose the body in a segmented shell, and developed large spikes to deter carnivores, the Lucifervermes exapted it for another use. Some of the spikes became jointed at their connection to the body, allowing their use as legs. Walking was sufficiently more efficient than crawling to more than make up for the heavy armor. Over the next several dozen million years, the spines developed into limbs with two joints, one at the 'hip' and one at the 'ankle'; these relatively stiff legs give the Lucifervermes a strange gait. They are named for their fearsome, horned appearance, reminiscent to some of the head of a medieval morningstar. The Lucifervermes are a significant component of the Cambrian benthic fauna. They are either detritivores, herbivores, or true omnivores depending on the species; all are too slow to pursue prey. Edited by Vultur-10, Dec 11 2009, 09:24 AM.

I had one in the works, but I don't think I'll get it in on time so I'll just post up what I've got to be judged. It was supposed to be a sessile animal with a central stem secured into the soil by a weighty foot, and many side-stems containing food catchers that appear out of holes along the side stem. The food catchers are so brushy and there are so many that the side stems are rarely ever visible. Stems have hard plating for protection, but the food catchers are soft and vulnerable so when they are touched or when the sea currents get too strong they withdraw back into the stems. Withdrawing food catchers into the stem is also how food gets to the digestive chamber (which is pretty much what the inside of the central stem is). Growth occurs both outwardly and upward. The plates are shed like exoskeleton. The top of the central stem is always budding new side stems. They are sexually reproducing, producing gametes from gonads on the ends of each stem, particularly the top of the central stem. Gonads are either male or female, there is no apparent pattern to which gonads are which sex. The gametes of both sexes swim. Fertilized offspring begin dividing on the sea current. Young quickly have to find a food source. First to form is a stomach chamber, then the first food catcher. At this stage the organism is microscopic and swims to the source of warm water using cilia-like hairs. Along the way they collect more food and grow a little bigger. Hopefully they have managed to remain in the warmer waters. Soon they become too big to swim, the cilia just push water over its surface rather than propel it. A weight forms at their bottom, which becomes their foot, which slowly drifts to the sea bottom. This is how they get from adult, to newly-planted offspring. That's all I managed to come up with so far. |

Both of those new groups sound awsome. Also I am glad somebody else likes the mobile Plant idea. |

Name (for now): Waders Anatomy: Most of them are tiny, roughly the size of a pinky nail, though others can be a few inches long. Their body is elongated with a wider bottom then a top, being made for nearly swimming (really they merely glide along the floor of shallow seas). Internally they have a simple nervous system, controlling six major muscles controlling their swim pattern (following a classic horizontal S). They have five eyes, three in the front and two on top (the two on top are to watch for predators). They have a tiny, toothless mouth-like opening in the front. They reproduce asexually. They have a single bone like shell made of chitin (they have not mineralized yet) at the top of their body for protection. For short bursts they can swim higher in the water, but stay mostly on the floor. |

Those Waders sound neat, but what is the difference between Chitin and Keratin? |

Keratin is a protein, chitin is a carbohydrate. They are actualy pretty similar though, and are used for a lot of the same things. A biochemical analogue on are own planet. |

I know its a bit late but nobody's posted since last night's deadline and I had an idea... A unicellular protist that lives colonially in a mucousy environment secreted by each other. This gives the colony weight so that it always sinks to the floor. It has a protective chitinous cell wall so they don't digest themselves. The digestive juices in the mucous solution digests most soft-bodied organisms it comes into contact with meaning the colony is constantly bathed in nutrients. Each individual organism can swim. Some use flagella, some use cilia, depending on the species. This helps them remain closer together, or re-form if their colony is disturbed. It also allows them to slowly move across the sea floor, practically cleaning it. I know it's past the deadline... but no harm in trying.
