  Cetacea - Wikipedia, the free encyclopedia
Cetaceans are nearly hairless, and are insulated by a thick layer of blubber.
Cetaceans evolved from land mammals (most likely from certain hoofed carnivores distantly related to hippopotamuses) that returned to the sea about 50 million years ago.
From this, cetaceans can discern the size, shape, surface characteristics and movement of the object, as well as how far away it is. This is called echolocation, and with it cetaceans can search for, chase and catch fast-swimming prey in total darkness.

 Mammals - Resources - Cetacean FAQs
However, it is the cetaceans that are the most specialised in the aquatic environment and for a long time even the most basic aspects of their biology remained a mystery.
Cetaceans sleep by floating at the surface of the sea with their blowholes exposed, some species rest during the day and others at night.
Cetaceans often live in environments where there is little light, such as the deep ocean or the turbid waters of rivers.

 CRESLI Cetacean page
Cetaceans and the Sirenians (dugongs and manatees) are the only two orders of mammals that are adapted to a fully aquatic existence.
Early analysis of fossil evidence led to the belief that cetaceans had evolved from mesonychians, an extinct group of archaic ungulates (hoofed mammals) that had wolf-like or hyena-like proportions and were adapted for rapid movement on land and had large heads with powerful jaws (Berta and Sumich 1999; Reynolds, Odell and Rommel 1999, Rice 1998).

 Cetacean Nation
The concept of a cetacean "nation" was originally conceived in 1961 by Dr. John Lilly, subsequently advocated in the 1970’s by Jacques Cousteau and Greenpeace, and promoted in the 1990's by Scott Taylor of the Cetacean Studies Institute of Santa Fe.
To ensure the survival of the cetaceans in light of the continuing onslaught by human beings, it is essential that they be recognized for what they truly are: non-terrestrial intelligent life forms.
Recognition of cetacean species as a nation and a separate group of intelligent, sentient beings that should be afforded the fundamental rights to survival and happiness in keeping with those afforded human beings in modern democratic societies.

Hairs on cetaceans are restricted to the head, with isolated follicles occurring on the lower jaw and the snout.
Cetaceans use up to 80 percent of their lung volume in a single breath, in contrast to humans, who use only 20 percent.
Recent studies based on genetic sequences have confirmed that all cetaceans were derived from a single ancestral stock and are closely related to the hoofed mammals in the order Artiodactyla, made up of the even-toed mammals, such as cattle, deer, and camels.

 HIST: Cetacean Science   (Site not responding. Last check: 2007-11-06)
It is over 150 years since the genlifting of the cetaceans, and in that time they have produced numerous notable scientists.
One of the few things that is known for certain about the way that cetaceans think is that they do not categorise the world in this way: they do not have the subject/object distinction in the same way as humans, and their view is more holistic.
Since the equivalent feature of cetacean thought is a complete mystery, the assumption that we have the faintest idea of what they are doing is almost certainly false.

The primary objective was to document the distribution of cetacean species occurring on the shelf of the Gulf of Alaska and to collect line-transect data for abundance estimation of cetacean species.
Surveys to determine distribution and abundance of cetaceans are costly and therefore often confined to coastal waters where the logistics are most practical or to areas of the ocean where marine mammal mortality associated with commercial fishing is particularly high.
The cetacean survey was conducted from the flying bridge at an eye height of approximately 12 m.

 PhysOrgForum Science, Physics and Technology Discussion Forums -> My Hypothesis On Why Cetacean's Beach Themselves
Cetaceans ancestors were orginally land walking animals with hooves! They evolved from the land into the sea millions of years ago, before man's short spell here began.
In a nutshell, my hypothesis is that over thousands, possibly millions of years and after millions of beachings from this selected group of sea mammals, cetacean's are being genetically altered, or mutated, as per darwins theory of natural selection to evolve back onto land from the sea.
I believe that all cetacean's have the same gene but only the 'selected' cetacean's genes are 'switched' on while the rest of the population's remain dormant.

 The Cetacean Declaration of Interdependence
When, in the course of Life, a family of living Beings, having endured centuries of attack upon and destruction of their lives and means of existence by an insensitive species, having determined to declare their status as Sentient Beings among the higher orders of Life, it becomes necessary to articulate it¹s implicit Nature.
We declare that the family of Cetaceans are co-equal with Humans in the eyes of the Creator, and are the Citizens of a new nation, one that, although it has existed in latent form for millions of years, until now had no need to be recognized.
The population of Cetaceans which is now living in Human-managed situations is of a special nature, and is to be given exceptional care.

 Cetacean bycatch, entanglement in fishing gear, marine mammals, whales
Accidental capture and entanglement in fishing gear is the biggest threat to whales, dolphins and porpoises worldwide, killing more than 300,000 animals per year.
While considerable progress has been made over the last decade in stemming bycatch problems in certain fisheries, advances in reducing cetacean mortality in fisheries have remained relatively localized and therefore have had limited impact on the problem worldwide.
Transferring the lessons learned in places where bycatch mitigation approaches have been successful or promising - and even where they have failed - is an important step toward reducing cetacean bycatch on a global scale.

States with fisheries that experience a cetacean by-catch should adopt a national plan of action to reduce the incidental mortality of cetaceans (see below the “technical note on developing a national plan of action for assessing and reducing the incidental catch of cetaceans in fisheries”).
States which determine that a national plan of action on cetacean bycatch is not necessary should review this decision on a regular basis, taking into account changes and expansions in existing fisheries and the development of new fisheries.
Lack of detailed information on the magnitude of the bycatch or the size and biology of particular cetacean populations should not be used as a reason for a lack of action.

CSI is an all volunteer, non-profit conservation, education, and research organization based in the USA, with volunteer representatives in 26 countries around the world.
The goal of the Cetacean Society International is to achieve on a global basis the "optimum utilization of cetacean resources" [1946 International Whaling Commission Treaty] through benign utilization and the elimination of all killing and captive display of whales, dolphins, and porpoises.
To this end, we seek in every peaceful way to minimize cetacean killings and captures, and to maximize activities that neither harm nor harass, such as regulated whale watching, nonlethal research, and widespread educational, aesthetic, and environmental programs relating to free-living whales, dolphins, and porpoises.

 GulfCet II Study: Cetacean Habitat in the Northern Gulf of Mexico
To determine the relationship between cetacean distribution and habitat characteristics, two dedicated cruises aboard the R/V Gyre were conducted in the eastern Gulf of Mexico in late summer of 1996 (Gyre96G06) and mid-summer of 1997 (Gyre97G08).
Cetaceans were subdivided into five groups based on large body size and deep diving ability (sperm whales, category 2), intermediate body size and dietary preference for squid (squid-eaters, Category 3), phylogenetic relationship and occurrence in deep water (<200 m) habitats (bottlenose and Atlantic spotted dolphin Category 5).
Cetacean sightings were grouped as follows: 1) Cetaceans (all species identified) 2) Sperm whales, 3) Squid-eaters (except for sperm whales).
