What is a "cetacean"?
A cetacean is a marine mammal belonging to the order Cetacea, which includes whales, dolphins, and porpoises. These creatures are known for their streamlined bodies, fin-like limbs, and adaptations for living in water.

Cetaceans play vital roles in marine ecosystems and are renowned for their elegance and allure in the world's oceans.
