The French Academy of Sciences ( French: Académie des sciences) is a Learned society, founded in 1666 by Louis XIV at the Concerning his educational background, Dujardin was largely self-taught.
Dujardin is primarily known for his work with microscopic animal life, and in 1834 proposed that a new group of one-celled organisms be called Rhizopoda; meaning "root-foot. Amoeboids are Unicellular lifeforms that mainly consist of Contractile vacuoles, a nucleus, and cytoplasm as their basic structure This name was later changed to Protozoa. Protozoa (in Greek πρῶτον proton "first" and ζῷα zoia "animals" are unicellular Eukaryotes (singular He refuted naturalist Christian Gottfried Ehrenberg's (1795–1876) concept that microscopic organisms are "complete organisms" similar to higher animals .

In Foraminifera, he noticed an apparently formless life substance that he named "sarcode"; which was later renamed protoplasm by Hugo von Mohl (1805-1872). The Foraminifera, ("Hole Bearers" or forams for short are a large group of Amoeboid Protists with reticulating Pseudopods fine This article has been the subject of edit wars and has been placed on probation Protoplasm is the living contents of a cell that are surrounded by a Plasma membrane. Hugo von Mohl ( 8 April 1805 &ndash 1 April 1872) was a German Botanist from Stuttgart. Dujardin also did extensive research regarding other invertebrate groups including echinoderms, helminths and cnidarians.

The standard author abbreviation Dujard is applied to species he described. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.
