What Fish Can Do We Can't

Small fish can answer surprisingly large questions.Zebrafish, killifish, and medaka have become indispensable model organisms in modern science. Their transparent embryos, rapid development, unusual regenerative abilities, short life cycles, and genetic accessibility allow researchers to observe biological processes that are far harder to study in humans.What Fish Can Do That We Can't explores how these animals are used to investigate heart regeneration, nerve repair, aging, genetics, vision, disease, environmental stress, behavior, toxicology, and drug development. It also looks at medaka in space, fish-inspired robotics, the use of processed fish skin in wound research, and the ethical questions surrounding fish as laboratory animals.The book explains what these models can genuinely reveal while drawing a clear line between experimental findings and medical promises. A regenerating zebrafish heart is fascinating, but it is not a ready-made treatment for a human patient. Understanding that distinction is part of understanding how modern biomedical research actually works.Written for curious readers rather than specialists, the book combines current scientific research with accessible explanations and detailed color infographics.For readers interested in biology, medicine, genetics, regeneration, aging, animal research, and the unexpected ways in which small aquatic vertebrates are changing science.
