Selected for their appeal in teaching protistology in schools, colleges and universities. Many species are particularly amenable for use in student projects for studying feeding, reproduction, motility organelles, nuclear apparatus and encystment. All supplied in 30ml cultures, (sufficient for up to 30 students). Amoeba Proteus is very large and vigorous strain which displays protoplasmic streaming (cyclosis), prey encapsulation and phagocytosis. An excellent textbook species for demonstrating pseudopodia and amoebae morphology.
