The name of this deep sea creature derives from the root words plankto- meaning wanderer and abyss- meaning deep. So its called the wanderer of the abyss.
Ocean Zone and Habitat
Planktobyss are deep sea dwelling creatures near the sea floor. They dwell in the Pelagic zone. Within the Pelagic Zone they exist in the Oceanic Zone. They are in the Aphotic Zone where there is no light and they strive in the Abyssalpelagic Zone between 4000-6000 meters. They are a wandering fish you do not stay in one place for more than a day. Almost like nomads they strive be moving constantly throughout the ocean. The water is extremely cold and there is a lot of pressure.
The Planktobyss is can be 3-12 inches in length. Also 2-7 inches in diameter because it is mainly a very round fish. Females are usually 3-5 inches and males are 7-12 inches long. The Planktobyss has the same pressure as the water surrounding it to not be crushed under extreme pressure from the water above. Considering there is no light, the Planktobyss has average size eyes but can sense minute vibrations in the water so it doesn't need to really on sight. It is all black because there is no need for color when there is no light.
The Planktobyss has three jet like fins that suck in water to propel them selves at ultra-high speeds. They use the two on the side to angle themselves left and right and the one on their behind is more flexible and can move according to whether or not they need to go up or down. They can pulse about up to 40 mph when hunting prey.
When the Abyssal Zone has so little oxygen, its adapted to have a slow metabolism and use as little of the energy from the last prey they hunted. When it takes water in to move around it takes out what ever little oxygen is in the water into its system and pushes out the oxygen less water for propulsion.
It feeds on various types of zooplankton and uses its circular mouth to suck in prey like it does when moving round. Since its a wandering fish it has a flexible food range also including small shrimps and more tiny organisms.
