What whale is the deepest diving whale?

Zhu Yewei's beaked whale or goose's beaked whale

Cavirostris), the only member of Ziphius, is the most widely distributed beaked whale. Although accustomed to the upper seawater, its known maximum diving depth is 299 1.9 meters (98 16 feet), which is the deepest diving depth for mammals in the world and can avoid ships. It is one of the most widely distributed beaked whales.

The name comes from Greek xiphos, "sword", Latin American high arch foot, "mouth", which refers to the retraction of the head in front of the stomata.

Ye Wei, a French anatomist, in his thesis "Contaminating Otsymens".

Fossil (1823) describes an imperfect skull species based on the Mediterranean coast from France for the first time. It was discovered by M. Raymond Gorsse in 1804 by a farmer in Foss, near the Rhone estuary province. Zhu Ye Wei named it Zifius.

Cavirostris, derived from the Latin word "hollow" or "concave" of high arch foot, is a specific name for the diagnostic characteristics of this species with reference to the deep hollow skull (this pre-cranial basin). Zhu Ye Wei thinks it represents the remains of an extinct species. It was not until 1850 that zoologists realized the nature of species. When Paul Gelve compared the model specimen with another model specimen, it ran aground in Areskiye, Ero province in May of the same year and found that they were the same.

The giant Ye Wei beaked whale is cigar-shaped, similar to other beaked whales, and it is difficult to distinguish it from many T whales at sea, about 5-7 meters long (16-

23 feet) and weighs about 2,500 kilograms (5,500 pounds). There is no significant difference between male and female individuals.

Its dorsal fin is curved and small, located in the back two-thirds of the head. Its flippers are also small and can be stuffed into the pockets of the body wall, probably to avoid rapid dive. Like other beaked whales, its trematode is very large and lacks the middle incision that all other whales have. The head is short and small. Zhu Yewei's middle-beaked whale has a short beak, which is slightly spherical compared with other species in its family. Wax gourd is white or cream-colored, and white stripes extend along the back to about two-thirds of the dorsal fin. Body color, some are dark gray and reddish brown. There are usually white scars. The shape of dorsal fin varies from triangle to sickle. Life expectancy is about forty years.

Giant-billed cetaceans such as squid, including Sparidae, Xenopidae, Brachionidae, Noctuidae, Octopus and Xenopidae; It also preys on deep-sea fish. In 20 14, scientists reported that they used satellite link tags to track Zhu Ye Wei's beaked whale off the coast of California, and found that it dived 2,992 meters (almost two miles) below sea level and held its breath for two hours 17 minutes, breaking two records: the deepest and longest diving record of marine mammals.

The beaked whale is distributed in deep sea and offshore waters, from tropical to cold temperate seas. In the North Pacific, it happened because of the Aleutian Islands in the north, but in the North Atlantic, Massachusetts in the north, and shetland islands in the east and west. In the southern hemisphere, south to Tierra del Fuego, South Africa, South Australia, New Zealand and chatham islands. Inland includes the Gulf of Mexico, the Caribbean Sea and the Mediterranean Sea.

The giant Ye Wei beaked whale is probably one of the most common and abundant beaked whales, and its number in the world may exceed 654.38 million. It is estimated that about 80,000 are in the tropical eastern Pacific, nearly 65,438+0,900 are on the west coast of the United States (excluding Alaska), and more than 65,438+05,000 are in Hawaii.

The measured beaked whale reached a maximum depth of 98 16 feet (2,992 meters), which made it the deepest diving mammal.
