Unlock the hidden life cycles of marine organisms and their astonishing generations.

This scholarly work surveys how certain animals foster their young through alternating generations, from club-shaped polypes to free-swimming larvae. The author pairs careful drawings with detailed explanations, drawn from observations in Iceland and other coastal settings.

Learn how different generations interact within a single lineage, including “nurse” forms and the emergence of young in the water.
See step-by-step descriptions of development, metamorphosis, and the metamorphic stages that lead to mature forms.
Explore the anatomy and function of tiny, transparent creatures through carefully annotated figures and plates.
Discover the observational approach that combines microscopy, drawing, and natural history to illuminate complex life cycles.

Ideal for readers of natural history, marine biology, and the history of early microscopy.
