Kepler 283-C

Brandon B. and Aidan E.

Speculated Planetary Characteristics

Kepler 283-c's surface is covered entirely by a shallow ocean that is rich with oxygen due to abundant photosynthetic organisms. The skies and oceans have a red-orange hue due to the color of Kepler 283. The mass of the planet (Calculated to be 6x Earth's mass) causes the atmosphere to be denser than that of Earth's. The near-circular orbit and short years (93 days) give the planet a fairly static climate.

The Masked Angler

The Masked Angler is an aquatic organism that makes its home in the shallow oceans of Kepler 283c. The creature's name comes from the long, bio-luminescent filament sprouting from the top of its head. This causes it to resemble an organism found in Earth's oceans who shares a similar feature- the anglerfish. It was after this resemblance that the creature was named.


The shallow oceans of Kepler 283c are filled with photoautotrophs who use chlorophyll to photosynthesize. These photoautotrophs cause the atmosphere, as well as the oceans, to be quite rich in oxygen. This, coupled with the dense atmosphere, allows for the native organisms of Kepler 283c to perform cellular respiration more efficiently. Though Kepler 283 is dimmer that our own Sun (0.1045x the Sun's luminocity), the close proximity of Kepler 283c to its parent star causes the star to appear only 10% dimmer that our Sun appears from Earth. The daytime sky would allow the brighter stars to be visible, even if only faintly. The nights would be illuminated only by the stars, as Kepler 283c lacks a known moon to illuminate the night time oceans. Visibility in the water is almost nonexistent at night, as the light from the stars cannot penetrate very deep into the water. For this reason, bio-luminescent organs are crucial for the night time activities of many lifeforms, similar to the lifeforms that inhabit the deep waters of Earth.

The different ecosystems of Kepler 283c are separated primarily by depth and latitude. The masked angler, reaching sizes of 2-4 meters long, is one of the largest inhabitants of its native depth. The only real threat that an adult masked angler will face is that of another adult masked angler.


The masked angler has a simple skeleton that is made up mostly of a spine, skull and numerous smaller bones, all composed of calcic bioceramic bone. Its rear end tapers to a flat tail, that sweeps up and down to propel the creature through the water.The masked angler also has two finlets on its sides that are bound to the back of the skull that act as stabilizers, similar to the pectoral fins of Earth fish.

The defining feature of the masked angler is its bright bio-luminous face and filament. The luminous cells are covered in a "hazy" transparent skin that scatters the light produced and gives the creatures entire face an even glow. The bright orange color of masked anglers face would appear to the other creatures of its habitat, as a bright, white light would appear to Earthly creatures.

The digestive system of the masked angler is not unlike that of most earthly fauna, though it is composed completely of organs analogous to those of earthly creatures. Food enters the mouth and passes through an esophagus to the stomach where the food is broken down. The broken down food then passes through a short intestinal tract, where the nutrients are absorbed, and waste is excreted through an opening on the masked anglers ventral side.


The masked angler is a solitary creature; any creature encountered is either prey or a mate. The "mask" of the masked angler is used to perform bio-luminescent displays that attract prey and mates, and is also used to confuse any threatening creatures. Mates are spared if they respond in turn with their own bio-luminescent display. The masked angler has no gender, possessing a singular organ that produces the cells analogous to eggs and sperm. When potential mates encounter one another, after the mating display is performed, the individuals latch onto one another momentarily as they trade "sperm", the go their separate ways. Fertilized eggs develop into large spheres with hard calcic shells that are deposited by the parent in open water. The egg drifts to a depth that is relatively free of predators large enough to threaten the egg, where it matures and eventually hatches.
