ichthyology
Finned creature science
Ichthyology is the branch of zoology devoted to the study of fish—their anatomy, behavior, classification, and evolution.
An ichthyologist might study shark migration patterns, catalog deep-sea species, or research freshwater ecosystems.
The field encompasses both scientific research and practical applications like fisheries management.
