The baiji (Chinese river dolphin) has become "Possibly Extinct" in the past century, while the vaquita and Yangtze finless porpoise are ranked Critically Endangered by the International Union for Conservation of Nature.Besides hunting, cetaceans also face threats from accidental trapping, marine pollution, and ongoing climate change.Mothers of some species fast and nurse their young for a relatively short period of time, which is more typical of baleen whales as their main food source (invertebrates) aren't found in their breeding and calving grounds (tropics).

Baleen whales have short hairs on their mouth, unlike the toothed whales.

Dolphins are commonly kept in captivity and are even sometimes trained to perform tricks and tasks, other cetaceans aren't as often kept in captivity (with usually unsuccessful attempts).

Cetaceans have been relentlessly hunted by commercial industries for their products, although this is now forbidden by international law.

The two parvorders, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have diverged around thirty-four million years ago.

Baleen whales have bristles made of keratin instead of teeth.
