Arthroplankers share many traits but are very diverse in appearance and characteristics. The top two pictures are some of the more common Arthroplankers. Most are lightweight with a density only slightly greater than water. Limbs and tails can be found on Arthroplankers. Protective coloration enables nearly all Arthroplankers to blend with their environment. The Arthroplanker vary in size from 2 to 40 feet long. Strobeplankers are their main source of food. Arthroplankers reside in shallow water and can also be found in depths down to 5000 feet.
Uniplankers are unicellular organisms which exihibit bioluminescence.Plankton is their main source of food. Bioluminescence occurs not only in the sea but also occurs in freshwater. The Uniplanker is a subspecies of the Arthroplanker. Uniplankers are of microscopic size and can be found down to depths of 100 feet.
Strobeplankers make up jelly fish and soft bodied shelled organisms. Uniplankers are their main source of food. Jelly fish possess stinging cells and a double pair of tentacles. Strobeplankers can be found down to depths of 500 feet. Strobeplankers live in both freshwater and seawater. Some strobeplankers range from sea snails to giant mopalias over 60 ft long! Due to the fact that Uniplankers can only be found down to depths of 300 feet, the strobeplankers will probably need to find another food source.
