Fine structural observations on oocyte development in monogeneans

open access: yesParasitology, 1976
SummaryThe ultrastructural changes accompanying oocyte differentiation in the ovaries of the monogeneans, Diclidophora merlangi, Diplozoon paradoxum and Calicotyle kröyeri have been described. In each case, oogenesis in the ovary proceeds as far as meiotic prophase in the primary oocyte.

Workshop no. 4. Biology of monogeneans

open access: yesParasitology, 1981
The oncomiracidia larvae of monogeneans are small, ciliated, relatively slow-moving organisms with a limited free-swimming life. For example, the oncomiracidium of the skin parasiteEntobdello, soleaeis 250 µm in length, swims at a speed of 5 mm/sec and lives for about 24 h (Kearn, 1967a).
