Otto Bütschli
Johann Adam Otto Bütschli (3 May 1848 – 2 February 1920) was a German zoologist and professor at the University of Heidelberg. He specialized in invertebrates and insect development. Many of the groups of protists were first recognized by him.
Life.
Bütschli was born Frankfurt am Main. He studied mineralogy, chemistry, and paleontology in Karlsruhe and became assistant of Karl Alfred von Zittel (geology and paleontology). He moved to Heidelberg in 1866 and worked with Robert Bunsen (chemistry). He received
with light sensitivity. Species of blue-pigmented "Eufolliculina" form extensive mats in the deep sea that have been called "blue mats".
Systematics.
Early classification schemes by Otto Bütschli, Alfred Kahl, Emmanuel Fauré-Fremiet, and John O. Corliss classified the heterotrichs as a subgroup of spirotrichs. They included groups such as Armophorida, Odontostomatida, Licnophorida, Clevelandellida, and Plagiotomida within the Heterotrichea. However, more recent classification systems, which have incorporated information from molecular phylogenetics, place the above groups within the
