Reproductive processes of scyphidiid peritrichs associated with limpet and haliotid hosts along the coast of South Africa
English: During the early 19th century a lot of progress was made in clarifying reproduction patterns and cycles in the kingdom Protozoa Goldfuss, 1818. During the first half of the 20th century various scientists studied the reproductive processes of peritrichs and made valuable contributions. Whil...
