Etymology

The word 'cetacean' comes from the Greek word 'ketos', meaning 'whale', and the Latin 'cetacea', which refers to the order of marine mammals that includes whales, dolphins, and porpoises. This term was first used in the scientific context in the early 19th century as marine biologists began to classify aquatic mammals systematically. As our understanding of marine life progressed, more emphasis was placed on the study of cetaceans and their ecological significance. The development of technology in marine biology, including sonar and underwater communication, has allowed researchers to learn more about the behaviors, habitats, and migration patterns of these fascinating creatures. Today, cetaceans are widely studied not only for their biological importance but also for their roles in marine ecosystems and the impact of human activity on their populations.
