Dictionary
dolphin : any of various small marine toothed whales (family Delphinidae) with the snout more or less elongated into a beak and the neck vertebrae partially fused
Note: While not closely related, dolphins and porpoises share a physical resemblance that often leads to misidentification. Dolphins typically have cone-shaped teeth, curved dorsal fins, and elongated beaks with large mouths, while porpoises have flat, spade-shaped teeth, triangular dorsal fins, and shortened beaks with smaller mouths. — Merriam-Webster See also OneLook
Encyclopedia
Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. — Wikipedia

- Where have all the right whales gone?on April 12, 2024 at 4:54 pm
Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine spatial planning, and industry regulations to mitigate risk to right whales.
- Toothed whale echolocation organs evolved from...on April 8, 2024 at 5:07 pm
Genetic analysis finds evidence suggesting that acoustic fat bodies in the heads of toothed whales were once the muscles and bone marrow of the jaw.
- Caller ID of the sea: Tagging whale communication...on March 25, 2024 at 3:41 pm
Biologists use a novel method of simultaneous acoustic tagging to gain insights into the link between whale communication and behavior
- Entanglements of humpback whales in fish farms...on March 21, 2024 at 7:53 pm
The first study of humpback whale entanglements in B.C. aquaculture facilities found eight over 13 years, with the curiosity of young whales a potential contributing factor.
- Scientists weigh up current status of blue whale...on March 20, 2024 at 8:05 pm
The largest living animal, the blue whale (Balaenoptera musculus) which averages about 27 meters in length, has slowly recovered from whaling only to face the rising challenges of global warming, pollution, disrupted food sources, shipping, and other human threats. In a major new study, biologists have taken a stock of the number, distribution and genetic characteristics of blue whale populations around the world and found the greatest differences among the eastern Pacific, Antarctic subspecies […]

The case of a Florida bottlenose dolphin found with highly pathogenic avian influenza virus, or HPAIV—a discovery made by University of Florida researchers in collaboration with multiple other agencies and one of the first reports of a constantly growing list of mammals affected by this virus—has been published in Communications Biology.
- First discovery in decades of blue whales near...on April 22, 2024 at 4:40 pm
Blue whales are fascinating animals. At 24–30 meters in length (longer than a basketball court) they are the largest creatures on Earth. They are also among the rarest. Estimates suggest that there are only about 5,000 to 15,000 blue whales left in the world.
- Whales and dolphins now have legal personhood in...on April 16, 2024 at 6:00 pm
Whales and dolphins have been officially recognized as "legal persons" in a new treaty formed by Pacific Indigenous leaders from the Cook Islands, French Polynesia, Aotearoa (New Zealand) and Tonga.
- Toothed whale echolocation organs evolved from...on April 8, 2024 at 2:02 pm
Dolphins and whales use sound to communicate, navigate and hunt. New research suggests that the collections of fatty tissue that enable toothed whales to do so may have evolved from their skull muscles and bone marrow.
- Scientists say these killer whales are distinct...on April 7, 2024 at 3:00 pm
More than 150 years ago, a San Francisco whaler noticed something about killer whales that scientists may be about to formally recognize—at least in name.
