Planet:Teleastrus III

Teleastrus III is a hypothetical planet in a solar system from the Triangulum galaxy. It is the third planet in it's system, Teleastrus, as it's name suggests. The planet is slightly smaller than Earth, at just 6,900 miles in diameter. Gravity is slightly lower. The planet it 70% water just like Earth, but life is different on the planet. There are no sapients, but life forms on Teleastrus III are unique compared to Earth.

Basic Land Vertebrate Anatomy
Land vertebrates have four limbs with 4-8 digits. There are six nostrils that line along the snout. They don't have any true jaws. In place of a jaw, there is a raspy toungue-like organ called a radula. On Earth, most mollusks have the same thing. It has chitinous "teeth" on it. The radula rasps on the meal, taking bits into the mouth. There are eyes that are stalked from the side of the head, but they're less evolved than the other senses. It is just a pinhole eye with photoreceptors and chromoreceptors at the bottom. Land vertebrates are usually better at hearing and smelling. To hear, they have a long horn that is hollow and is sensitive to vibration. In some species, it is also used as a weapon or for mating display. There are no vertebrates with fur, although there are some marsupial-like beings that feed their young on milk. In polar reigons, there are either thick insulating scales or blubber to keep the animal warm. In higher forms, there are three genders, one is male, one is female, and one holds the eggs and sperm. The holder gender has a long tube which an ovipositor or phallus enters. The holder also cares for the young. The male guards the young, and the female just goes on her own finding more holders to mate with.

Basic Plant Anatomy
The "plants" on Teleastrus III are not actually plants. They evolved from water-dwelling animals that did a symbiosis with black photosynthetic beings. The animals evolved a webbing around the legs to store the photosynthetic cells in. The animals then ventured onto land. As the animal gets it's energy from photosynthesis, the digestive system begins to disappear. The many oral tentacles that were used to filter food served as "roots and dug into the ground, developing root hairs to collect water underground. To adapt to the lack of oxygen on land, the plant part takes over the entire body, thus breathing carbon dioxide. As there were nothing to eat the plants on land, the nervous system digenerates and eventually disappears.

Plants on Teleastrus III have photosynthetic webbing supported by fleshy lobes that were once legs, as stated above. On the front and back of plant is an organ that breathes. It is turned down so when it rains, it does not drown the plant. The hemocoel in the ancestrial animal form a vascular system which brings water and nutrients to all parts of the body.

Plants reproduce by sexual spores. The spores are released from the breathing organ. Plants are hermaphroditic. When two spores of the opposite gender touch eachother, they land on any place the wind takes them. When conditions are favorable, the two spores form a zygote which divides to form many cells, and then a new plant grows.
