Mobula Pectinata
''Mobula'' is a genus of rays in the family Mobulidae that is found worldwide in tropical and warm, temperate seas. Some authorities consider this to be a subfamily of the Myliobatidae (eagle rays). Their appearance is similar to that of manta rays, which are in the same family, and based on genetic and morphological evidence, the mantas belong in ''Mobula'' (they are traditionally in their own genus ''Manta''). Species of this genus are often collectively referred to as "devil rays", "flying mobula", or simply "flying rays", due to their propensity for breaching, sometimes in a spectacular manner. These rays gather in groups and leap out of the surface into the air up to around two metres before splashing back into the water. Depending on the species, the devil rays can attain widths up to , the largest being second only to the manta rays in size, which can reach . Despite their size, little is known about the devil rays, much of it anecdotal; the manta rays are better know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mobula Mobular
The devil fish or giant devil ray (''Mobula mobular'') is a species of ray in the family Mobulidae. It is currently listed as endangered, mostly due to bycatch mortality in unrelated fisheries. Description The devil fish is larger than its close relative the lesser devil ray. It grows to a length of disk , making it one of the largest rays. It possesses a spiny tail. The devil fish is the third largest species in the genus ''Mobula'', after the oceanic and reef manta rays. It is the only mobulid species that lives in the Mediterranean Sea. The species has been observed to have a maximum recorded length of disk width of 5.2 meters (roughly 17 feet). However, those data are unreliable and are allegedly misunderstood as Giant oceanic Manta Rays that have strayed into the Mediterranean. It is also considered to be the only Devil fish with a tail spine. The species is also considered endangered given its decreasing population density. Distribution and habitat The Devil fish is m ...

Friedrich Gustav Jakob Henle
Friedrich Gustav Jakob Henle (; 9 July 1809 – 13 May 1885) was a German physician, pathologist, and anatomist. He is credited with the discovery of the loop of Henle in the kidney. His essay, "On Miasma and Contagia," was an early argument for the germ theory of disease. He was an important figure in the development of modern medicine. Biography Henle was born in Fürth, Bavaria, to Simon and Rachel Diesbach Henle (Hähnlein). He was Jewish. After studying medicine at Heidelberg and at Bonn, where he took his doctor's degree in 1832, he became prosector in anatomy to Johannes Müller at Berlin. During the six years he spent in that position he published a large amount of work, including three anatomical monographs on new species of animals and papers on the structure of the lymphatic system, the distribution of epithelium in the human body, the structure and development of the hair, and the formation of mucus and pus. In 1840, he accepted the chair of anatomy at Zürich an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The paramesonephric duct (Müllerian duct) was named in his honor. Life Early years and education Müller was born in Koblenz, Coblenz. He was the son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself to become a Roman Catholic Priest.

Mobula Japanica
The spinetail devil ray (''Mobula japanica''), also known as the spinetail mobula ray or Japanese mobula ray, is a species of pelagic marine fish which belongs to the family Mobulidae. It is found throughout the tropical and sub-tropical waters of the Indo-Pacific and eastern Atlantic Ocean. Taxonomy Some analyses suggest that the species should be considered conspecific with the devil fish (''Mobula mobular''). It is no longer recognised as a species by the IUCN. Description The spinetail mobula ray is a large ray which can grow up to a maximal width of 3.1 m (average width 2.3 m). Like most rays, it is dorsoventrally flattened and has relatively large triangular pectoral fins on either side of the main body disc. At the front, it has a pair of cephalic fins which are forward extensions of the pectoral fins. These can be rolled up in a spiral for swimming or can be flared out to channel water into the ventral mouth when the animal is feeding. The background body coloration of ...

Mobula Eregoodootenkee
''Mobula eregoodootenkee'', the pygmy devil ray or longhorned mobula, is a species of ray in the family ''Mobulidae''. It is endemic to the Indian Ocean and central-west Pacific Ocean. It ranges from South Africa in the west to the Philippines in the east, north to Vietnam, and south to the northern coast of Australia. It is a brownish-grey colour, with a whitish underside.

Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist. Works As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. He was also the first to observe gloves as a preventative against infection in medical surgery. In 1758, the gloves he observed were made from the cecum of the sheep, rather than rubber, which had not yet been discovered. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection, which was lost during the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.
