Die Entstehung der Sexualzellen bei den Hydromedusen: Ein Beitrag zur Kenntniss ihrer Biologie (German Edition)

Discover how sexual cells form in hydromedusae with a detailed, plate‑driven atlas. This classic work combines careful observations with illustrated, life‑like drawings to show where and how eggs and sperm develop in various hydrozoan species. Rich in descriptive detail, it guides readers through the anatomy of gonads, the pathways of radiating canals, and how development can differ between types of colonies and life stages. What you’ll find inside: - Clear, microscope‑level figures that relate to real specimens and their growth - Explanations of where germ cells arise and how they migrate within the tissue - Comparisons across several hydrozoan groups, with attention to variability and progression - Notes on how environmental factors might influence gonad development and placement Ideal for students and researchers seeking a visual, methodical look at early hydrozoan reproduction, and for anyone interested in the history of zoological microscopy.
