plankton's main habitat's are Bikini Bottom and Rock Bottom. Many own restaurants throughout (the most famous being Sheldon Plankton with his "nastiest in Bikini Bottom" restaurant award. There they serve various forms of Chum ( mad e up of jellyfish squeezing, seahorse snout, whale blubber, and a sprinkle of anchor rust). It is the most absolutely most disgusting thing I've ever tasted. I had to go to the hospital 3 times to get my stomach pumped in 4 days! Plankton provide food for whoever will buy that!

Plankton are any drifting organism that inhabits the pelagic zone of oceans, seas, or bodies of fresh water. It is a description of life-style rather than a genetic classification. They are widely considered to be some of the most important organisms on Earth, due to the food supply they provide to most aquatic life.
