Etymology
The term "Cetacea" is derived from the Ancient Greek word "κῆτος" (kētos), which translates to "large sea creature" or "sea monster". The term was first used in scientific nomenclature by Carl Linnaeus in the 10th edition of his Systema Naturae.
Classification
Cetaceans are divided into two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales). Mysticeti includes species like the blue whale and humpback whale, while Odontoceti includes species like the sperm whale, killer whale, and various species of dolphins and porpoises.
Anatomy
Cetaceans have a streamlined body designed for fast swimming. They have a horizontal tail fin, known as a fluke, used for propulsion, and a dorsal fin for stability. Their forelimbs are modified into flippers. They have blowholes on top of their head for breathing when they surface.
Behavior
Cetaceans are known for their intelligence and complex social structures. Some species, like dolphins, are known for their playful behavior. They communicate using a series of clicks, whistles, and body movements.
Conservation
Many species of cetaceans are threatened or endangered due to human activities such as hunting, habitat destruction, and pollution. Conservation efforts are ongoing to protect these species and their habitats.
