Pond Water An amazing world exists just beyond the naked eye. Pond water is one place to investigate this landscape of single cells that behave as independent organisms. Biologists have named this group, the protists. This report will fill you in on ones that can be most likely found in ponds. Protist, were around long before plants and animals appeared. Fossil protists have been found in rocks dated at more than 1.8 billion years old. In fact, your local pond is a very good place to find protists very similar to those that started the lines of multi-cellular life --and these organisms seem relatively unchanged from that ancient time. The simplest of all animals is the protazoa in Greek this name means “first animal.” There are four major classes of the protazoa. The simplest of these are the amoeboid. The amoeboid are found under the class name Sarcodina, some examples of these organisms are amoeba proteus, endamoeba coli, and endomoeba histolytica. These organisms are mainly parasites and are mostly free living. They reproduce by binary fission where they split themselves in half. Another more complex class is called the Infusoria.
