In this book, the editors present a view of the socioecology of primates and cetaceans in a comparative perspective to elucidate the social evolution of highly intellectual mammals in terrestrial and aquatic environments. Despite obvious differences in morphology and eco-physiology, there are many cases of comparable, sometimes strikingly. Cetaceans are mammals that have adapted to aquatic life and live exclusively in the water. The term Cetacea in biological terms means whale or (originally) large sea animal. There are three types of marine mammals that compose the cetacean species which include whales, dolphins and porpoises. Although the term whale can be used to refer to all cetaceans it usually .
Cetaceans Protecting Canada’s endangered whales through scientific research and collaboration Dr. Andrew Trites will receive $1 million over five years for research on Southern Resident Killer Whales. Historical data on abundance and distribution of cetaceans are scarce or lacking, so for most species the data are insufficient to assess their status. Given the lack of data, it is not possible to identify whether there is a cause-effect relationship between human activities .
The Order Cetacea is the group of marine mammals that includes the cetaceans - the whales, dolphins and porpoises.

Whales, Dolphins, and Porpoises: Cetaceans. Cetaceans are completely aquatic mammals: they feed, mate, calve, and suckle their young in the water. They are the most specialized mammalian swimmers. Some are capable of maintaining speeds up to 25 miles per hour, diving to depths of 10, feet, and remaining submerged up to 2 hours.
