Jelly-Fish, Star-Fish, and Sea-Urchins: Being a Research on Primitive Nervous Systems

The book invites listeners into the quiet world of marine invertebrates, where the translucent jelly‑fish and the striking star‑fish become more than seaside curiosities. The author’s reverence for their beauty is matched by a methodical curiosity, guiding the audience through careful observations that reveal hidden details of form and movement. Written for both the lay enthusiast and the practicing physiologist, the narrative balances vivid description with clear scientific explanation, making complex ideas feel approachable.

Through a series of meticulously recorded experiments, the work explores how these simple creatures sense and respond to their environment. Chapters detail the anatomy of medusae, the coordination of their pulsations, and the effects of various stimuli and poisons, before turning to the nervous structures of star‑fish and sea‑urchins. Original illustrations and excerpts from the author’s Royal Society papers enrich the listening experience, offering a comprehensive glimpse into the early study of primitive nervous systems.
