Forelimbs have evolved into rigid pectoral fins for steering, while hind limbs have completely disappeared within the body. Modern taxonomy divides this order into two primary suborders: Mysticeti, the baleen whales, and Odontoceti, the toothed whales.
Cetacean Definition Species Diversity: Exploring Evolutionary Splits and Ecological Roles
Evolutionary Journey from Land to Sea. This classification is not merely academic; it reflects deep evolutionary splits and distinct ecological roles.
They possess blowholes located on the top of their heads, allowing them to exhale and inhale rapidly at the surface while minimizing water intake. Many species face severe threats from human activities, including entanglement in fishing gear, ship strikes, ocean noise pollution, and the devastating impacts of climate change on their prey populations.
