cetacean : any of an order (Cetacea) of aquatic mostly marine mammals that includes the whales, dolphins, porpoises, and related forms and that have a torpedo-shaped nearly hairless body, paddle-shaped forelimbs but no hind limbs, one or two nares opening externally at the top of the head, and a horizontally flattened tail used for locomotion — Webster See also OneLook

Cetacea is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver. — Wikipedia

Science
Cetology is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific order Cetacea. — Wikipedia
Mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as “mastology,” “theriology,” and “therology.” The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management. — Wikipedia

- Inbreeding contributes to decline of endangered...on March 20, 2023 at 6:37 pm
The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.
- Unraveling whale entanglement risk factors off...on March 20, 2023 at 6:37 pm
New research is beginning to unravel the times of year and locations where whales are at greatest danger of entanglement in fishing gear on the Oregon Coast.
- Minke whales are as small as a lunge-feeding...on March 13, 2023 at 4:09 pm
A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
- Toothed whales catch food in the deep using vocal...on March 3, 2023 at 3:53 pm
Toothed whales, such as dolphins, killer whales and sperm whales communicate and catch food exclusively with sound. Now researchers have for the first time found they evolved a new sound source in their nose that is functionally the same as the human larynx.
- Centuries of whaling data highlight likely...on March 1, 2023 at 1:52 am
Centuries-old whaling records show how southern right whales are altering their feeding habits.

France's top administrative court on Monday ordered the government to ban fishing in parts of the Atlantic to protect dolphins which have washed up dead in their hundreds.

False killer whales off the Northern Australia coast need their conservation status reviewed because of similarities they share with groups from Hawaii listed as Endangered in the U.S., a Charles Darwin University (CDU) researcher says.

An international scientific study, led by the UPC's Laboratory of Applied Bioacoustics (LAB), shows that noise from human operations at sea damages marine invertebrates and ocean ecosystems. Published in Frontiers in Marine Science, the work points out that noise pollution at sea can even cause death in some marine species.
- Mysterious new behavior seen in whales may be...on February 28, 2023 at 8:48 pm
In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behavior being described in ancient accounts of sea creatures, recorded more than 2,000 years ago.

The Laboratoire Sous-marin Provence Méditerranée (LSPM) lies 40 km off the coast of Toulon, at a depth of 2,450 m, inaccessible even to sunlight. Through this national research platform run by the CNRS in collaboration with Aix-Marseille University (AMU) and IFREMER, scientists will investigate undersea unknowns while scanning the skies for neutrinos. These elementary particles of extraterrestrial origin know few obstacles and can even traverse our planet without bumping into a single atom.
