Ichthyology is the branch of zoology that focuses on the study of fish. This field explores various aspects of fish life, including their anatomy, behavior, ecology, and evolution. Ichthyologists, the scientists who specialize in this area, often conduct research to understand fish populations, their habitats, and their roles in aquatic ecosystems. Fish are incredibly diverse, with thousands of species ranging from tiny gobies to massive whalesharks. Understanding ichthyology is essential for conservation efforts, as many fish species face threats from overfishing, habitat loss, and climate change. By studying fish, scientists can help protect these vital creatures and their environments.
