What was the name of the whale that Gray discovered?
The correct genus was a point of contention for these whales, so Dolichodon traversii was later corrected to Mesoplodon traversii. In response to Hector's analysis, and explaining the need to name a new species, Gray noted that, "‘ Mesoplodon layardi (or as I should call it, Dolichodon layardi) has a much longer and attenuated lower jaw, and much more slender teeth than the Chatham Island specimen", in Transactions of the New Zealand Institute (PDF).
How many skull fragments does a spade-toothed beaked whale have?

In December 2010, an incredible discovery was made when two whales stranded themselves and died on Opape Beach in New Zealand. The adult female was 5.3m long and the young male was 3.5m long. Initially identified as the common Gray's beaked whale ( Mesoplodon grayi), a team of researchers led by Kirsten Thompson from the School of Biological Sciences at the University of Auckland sequenced two mitochondrial DNA regions and compared them to the existing three bone specimens to discover that these were never-before-seen spade-toothed whales.

What is the most endangered whale in the world?
There are three species of right whale, but the North Atlantic right whale ( Eubalaena glacialis) has suffered some of the greatest population declines, making it the most endangered whale species on the planet and causing the IUCN to list it as critically endangered .
Why are right whales endangered?
Right whales were among the whales most heavily targeted by whalers in the 18th and 19th centuries, as they were some of the most convenient to hunt and also had a high blubber content. Their name comes from the whalers' belief that they were the "right" whales to hunt since they not only swam near shore but also floated conveniently on the surface of the water after being killed. There are three species of right whale, but the North Atlantic right whale ( Eubalaena glacialis) has suffered some of the greatest population declines, making it the most endangered whale species on the planet and causing the IUCN to list it as critically endangered .
What are the threats to the cetaceans?
Dolphins and porpoises are severely threatened by incidental entanglement in gillnets, which accounts for a vast majority of human-caused dolphin and porpoise deaths. Furthermore, climate change and the increased presence of humans in bodies of water around the world pose threats to all cetaceans. Today, the International Union for Conservation of Nature (IUCN) lists 14 of the 89 extant species of cetaceans as Endangered or Critically Endangered, including five endangered whale species, two endangered porpoise species, and seven endangered dolphin species.
Why are whales not hunted?
The sei whale ( Balaenoptera borealis) is found in every ocean on earth but wasn't widely hunted in the 19th and early 20th centuries because it was thinner and less blubbery than other baleen species. However, by the 1950s, whalers began heavily targeting sei whales after populations of more desirable species like right whales were decimated as a result of overexploitation. The harvesting of sei whales peaked from the 1950s until the 1980s, reducing the global population dramatically. Today, sei whale populations are approximately 30 percent of what they were prior to the 1950s, causing the IUCN to label the species as endangered .
How many species of cetaceans are endangered?

What do baleen whales eat?
Members of the first group, the Mysticeti or baleen whales, are filter feeders characterized by their baleen plates, which they use to filter plankton and other small organisms out of the water. The diets of baleen whales allow them to accumulate large quantities of blubber, which made them favorite targets of 18th- and 19th-century whalers seeking to boil down blubber into valuable whale oil. Centuries of intensive hunting left most baleen species in shambles, and since they reproduce slowly, scientists worry that they're now more vulnerable to threats like pollution and ship strikes that might have otherwise been minor. Although commercial whaling was banned in 1986 by the International Whaling Commission (IWC), some species like the sei whale are still heavily targeted by Japan, Norway, and Iceland, which dodge or defy the IWC moratorium.
How big is a blue whale?
The blue whale ( Balaenoptera musculus) is the largest animal ever known to exist with a maximum length of around 100 feet and a maximum weight of about 190 tons. Prior to the influx of whaling in the 19th century, the blue whale was found in all of the world's oceans in abundant numbers, but over 380,000 blue whales were killed by whalers between 1868 and 1978. Today, the blue whale is still found in every ocean on earth but in far smaller numbers, with an estimated global population of only 10,000-25,000 — a sharp contrast from the estimated global population of 250,000-350,000 at the start of the 20th century. The IUCN has thus listed the species as endangered .

When did whales go extinct?
Whaling started as early as the 1500s and continued into the mid-20th century. Between 1911 and 1933 alone, nearly 1500 western gray whales were killed.

In recent years, several western gray whales have been found dead, entangled and drowned in Japanese fishermen’s nets. And their summer feeding grounds near Sakhalin Island are now home to large-scale offshore oil and gas rigs as well as ongoing seismic testing and underwater noise. The western gray whale population is slowly growing but experts say the death of just one mature female per year could send it back towards extinction.

Where are the whales that beached themselves?
In December of 2010, two whales—an adult female and a male calf—beached themselves on Opape Beach in the Bay of Plenty, New Zealand. They were originally thought to be Gray’s beaked whales, the most common species of whale to beach in New Zealand. But months later, when DNA researchers analyzed the bodies, they were shocked. The whales were actually spade-toothed beaked whales, one of the rarest whale species. So rare, in fact, that nobody had ever seen one before!
