Cách sử dụng
The word 'cetacean' is used to describe a group of marine mammals that includes whales, dolphins, and porpoises. You'd use this word when talking about any of these animals, their behavior, or their habitat. For example, "I learned about cetaceans in my marine biology class" or "The cetacean population is at risk due to human activity." It's a more scientific word, so you might come across it in academic or specialized contexts.
