Community and Production Information |
Foi (Plural: Fee) is the common name for all unicellular members of the gastroboskia kingdom, and specially the extoileisn family.
Anatomy
Foi usually take the form of a slug like creature with three eyes, but are actually a complex single-celled organism with multiple nuclei, similar to earth's Slime Molds. Their stomachs are located on their bellies, which are sticky to pick up organic materials. They have muscle-like fibers in their cytoskeleton, similar to an amoeba or a muscle.
Behavior
Most of the species of Foi swim around letting organic material attach to their stomachs, then curling into a ball to digest it.
Breathing and Blood
Foi are single-celled organisms, therefore they have no blood, only cytoplasm. Foi breath in through their cell membrane.
Diet & Energy
Most Foi gather organic materials from the water or the ocean floor. As a result of this, almost all Foi are either filter feeders or detrivores. Some, however, have evolved a parasitic lifestyle.
Evolution
All Foi originated from the foi which was a direct descendant of Sceletus Praetereo. Sceletus Praetereo was a cell that fragmented easily and received energy from digesting any organic particles that ran into it. It later evolved muscles to help it capture cells.
Locomotion
Most Foi move by rippling the "wings" on their sides to propel them through the water or over sand. A notable exception is the rolling foi, which curls up into a ball and rolls across the sea floor.
Reproduction
Almost all Foi rely on fragmentation as their means of reproduction, although species have evolved different methods, like asexual budding and spores.
Senses
Foi have three eyes located at the front of their body, and can pick up vibrations in the water to detect movement.
Size
Foi are generally only a few centimeters long, most of them are an even one centimeter.
Types of Foi
While most types of Foi conform to the basic body pattern, there are some exceptions.
Decedents of sucking foi - These Foi are parasitic, and live on the dark giant shovelhead. They are circular instead of elongated.
Decedents of sack foi - These Foi have a flap of skin on their underside that helps them filter feed.
Decedents of rolling foi - These Foi have turned inside-out and roll across the sea floor picking up organic material.
Decedents of featherbelly foi - These Foi have long feathered appendages hanging down from their bellies to improve filter feeding.
