Pygmy Beaked Whale
The pygmy beaked whale (''Mesoplodon peruvianus''), also known as the bandolero beaked whale, Peruvian beaked whale and lesser beaked whale, is the smallest of the mesoplodonts and one of the newest discoveries. There were at least two dozen sightings of an unknown beaked whale named ''Mesoplodon sp. A'' before the initial classification, and those are now believed to be synonymous with the species. The species was formally described in 1991, based on ten specimens obtained from Peru between 1976 and 1989, including a adult male as the type specimen. A specimen that stranded at Paracas, Peru in 1955 (first tentatively identified as Andrews' beaked whale) has since been identified as a pygmy beaked whale. Since 1987, there have been an additional 40 sightings of the species, for a total of 65 (as of 2001). Description The body of the pygmy beaked whale is the rather typical spindle shape of the genus, although the tail is unusually thick. The melon is somewhat bulbous and slopes do ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesoplodon
Mesoplodont whales are 16 species of toothed whale in the genus ''Mesoplodon'', making it the largest genus in the cetacean order. Two species were described as recently as 1991 (pygmy beaked whale) and 2002 (Perrin's beaked whale), and marine biologists predict the discovery of more species in the future. A new species was described in 2021. They are the most poorly known group of large mammals. The generic name "mesoplodon" comes from the Greek ''meso''- (middle) - ''hopla'' (arms) - ''odon'' (teeth), and may be translated as 'armed with a tooth in the centre of the jaw'. Physical description Mesoplodont beaked whales are small whales, (pygmy beaked whale) to (strap-toothed whale) in length, even compared with closely related whales such as the bottlenose whales and giant beaked whales. The spindle-shaped body has a small dorsal fin and short and narrow flippers. The head is small and tapered and has a semicircular blow hole that is sometimes asymmetric. The beak, which ...

Andrews' Beaked Whale
Andrews' beaked whale (''Mesoplodon bowdoini''), sometimes known as the deep-crest beaked whale or splay-toothed whale, is one of the least known members of a poorly known genus. The species has never been observed in the wild, and is known only from specimens washed up on beaches. Taxonomy The species was first described in 1908 by the American scientist Roy Chapman Andrews from a specimen collected at New Brighton Beach, Canterbury Province, New Zealand, in 1904. He named it in honor of George S. Bowdoin, a donor and trustee to the American Museum of Natural History. Description The body of Andrews' beaked whale is robust in comparison with other members of the genus. The melon is low, and the beak is short and thick. The lower jaw is peculiar in that halfway through it rises up significantly with the teeth extending over the rostrum. The head also sometimes has a light patch on the sides, more prominent in the males. The male, overall dark gray to black, has a lighter "saddle" ...

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monterey Bay
Monterey Bay is a bay of the Pacific Ocean located on the coast of the U.S. state of California, south of the San Francisco Bay Area and its major city at the south of the bay, San Jose. San Francisco itself is further north along the coast, by about 75 miles, accessible via Highway 1 and Highway 280. Santa Cruz is located at the north end of the bay, and Monterey is on the Monterey Peninsula at the south end. The "Monterey Bay Area" is a local colloquialism sometimes used to describe the whole of the Central Coast communities of Santa Cruz and Monterey counties. Toponymy The first European to discover Monterey Bay was Juan Rodríguez Cabrillo on November 16, 1542, while sailing northward along the coast on a Spanish naval expedition. He named the bay ''Bahía de los Pinos'', probably because of the forest of pine trees first encountered while rounding the peninsula at the southern end of the bay. Cabrillo's name for the bay was lost, but the westernmost point of the penin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Oaro
Oaro is a settlement close to the Pacific Ocean Coast of north Canterbury, in the South Island of New Zealand. Oaro is within Kaikoura District on State Highway 1 and on the South Island Main Trunk railway, 20 kilometres south of Kaikoura. It lies on a small flood plain close to the mouth of the Oaro River, which reaches the ocean just to the north of Oaro. The headland of Piripaua (Spyglass Point) and the associated Haumuri Bluff are located just to the south of the settlement. There is some conjecture about Oaro's etymology, though it is definitely Māori; it has been suggested that it could mean "the place at the front", "the place of swamp", or "the place of a wish". Alternatively it could mean "The place of Aro", which may have been the name of a prominent local Māori individual. The area around Oaro was badly affected by the 2016 Kaikoura earthquake Sixteen or 16 may refer to: *16 (number), the natural number following 15 and preceding 17 *one of the years 16 BC, ...

List Of Cetaceans
Cetacea is an infraorder that comprises the 94 species of whales, dolphins, and porpoises. It is divided into toothed whales (Odontoceti) and baleen whales (Mysticeti), which diverged from each other in the Eocene some 50 mya (unit), million years ago (mya). Cetaceans are descended from land-dwelling hoofed mammals, and the now extinct archaeocetes represent the several transitional phases from terrestrial to completely aquatic. Historically, cetaceans were thought to have descended from the wolf-like mesonychids, but cladistic analyses confirm their placement with even-toed ungulates in the order Cetartiodactyla. Whale populations were drastically reduced in the 20th century from intensive whaling, and the activity was globally banned in 1982. Smaller cetaceans are at risk of accidentally getting caught by fishing vessels using, namely, seine fishing, drift netting, or gill netting operations. Conventions The following is a list of currently existing (or, in the jargon of ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
