Cyclops Roundleaf Bat
The cyclops roundleaf bat or cyclops leaf-nosed bat (''Doryrhina cyclops'') is a species of bat in the family Hipposideridae found in the forests of equatorial Africa. Description Cyclops roundleaf bats are relatively small, with adults ranging from in total length, including a tail approximately long. With an average weight of , females are significantly larger than males at just . The body is covered in thick woolly fur, which is a dark brown in colour, grizzled with lighter flecks on the tips of the hairs. The wings are very dark brown, almost black, in colour. The ears are long and narrowly pointed. The nose-leaf has a distinctive shape, with a rounded horseshoe shape over the muzzle and a posterior leaf with two projections on each side. Both parts of the leaf also possess small club-like structures projecting from their mid-line. The "cyclops" part of the bat's name comes from the presence of a narrow circular opening in the centre of the forehead, just behind, and normal ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch Aristocracy (class), aristocrat, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna japonica'' (1844–1850). Temminck was the first dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Coenraad Jacob Temminck
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1853
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Bats Of Africa
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochirop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hipposideros
''Hipposideros'' is one of the most diverse genera of bats, with more than 70 species. They are collectively called roundleaf bats after the shape of their nasal ornament. It is the type genus of the family Hipposideridae. It is divided into species groups based on morphology. Species included in this genus are ''armiger'' species group * Great roundleaf bat, ''H. armiger'' * Lesser great leaf-nosed bat, ''H. turpis'' * Pendlebury's roundleaf bat, ''H. pendlebury'' * Ha Long roundleaf bat, ''H. alongensis'' ''bicolor'' species group *Dusky leaf-nosed bat, ''H. ater'' * Benito roundleaf bat, ''H. beatus'' * Bicolored roundleaf bat, ''H. bicolor'' * Short-headed roundleaf bat, ''H. breviceps'' * Sundevall's roundleaf bat, ''H. caffer'' * Spurred roundleaf bat, ''H. calcaratus'' *Fawn leaf-nosed bat, ''H. cervinus'' * Ashy roundleaf bat, ''H. cineraceus'' * Large Mindanao roundleaf bat, ''H. coronatus'' * Cox's roundleaf bat, ''H. coxi'' *Timor roundleaf bat, ''H. crumeniferus'' * ...

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, ''gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically or biochemically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency Modulated
Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing. In analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the instantaneous frequency deviation, i.e. the difference between the frequency of the carrier and its center frequency, has a functional relation to the modulating signal amplitude. Digital data can be encoded and transmitted with a type of frequency modulation known as frequency-shift keying (FSK), in which the instantaneous frequency of the carrier is shifted among a set of frequencies. The frequencies may represent digits, such as '0' and '1'. FSK is widely used in computer modems, such as fax modems, telephone caller ID systems, garage door openers, and other low-frequency transmissions. Radioteletype also uses FSK. Frequency modulation is wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Echolocation
Echolocation, also called bio sonar, is a biological sonar used by several animal species. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting in various environments. Echolocating animals include some mammals (most notably Laurasiatheria) and a few birds, especially some bat species and odontocetes (toothed whales and dolphins), but also in simpler forms in other groups such as shrews, and two cave-dwelling bird groups, the so-called cave swiftlets in the genus ''Aerodramus'' (formerly ''Collocalia'') and the unrelated oilbird ''Steatornis caripensis''. Early research The term ''echolocation'' was coined in 1938 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. As Griffin described in his book, the 18th century I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cicada
The cicadas () are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed. Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drumlike tymbals. The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur all around the world in temperate to tropical climates. They typically live in trees, feeding on watery sap from xylem tissue, and laying their eggs in a slit in the bark. Most cicadas are cryptic. The vast majority of species are active during the day as adults, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawk Moth
The Sphingidae are a family of moths (Lepidoptera) called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as “hornworms”; it includes about 1,450 species. It is best represented in the tropics, but species are found in every region.Scoble, Malcolm J. (1995): ''The Lepidoptera: Form, Function and Diversity'' (2nd edition). Oxford University Press & Natural History Museum London. They are moderate to large in size and are distinguished among moths for their agile and sustained flying ability, similar enough to that of hummingbirds as to be reliably mistaken for them. Their narrow wings and streamlined abdomens are adaptations for rapid flight. The family was named by French zoologist Pierre André Latreille in 1802. Some hawk moths, such as the hummingbird hawk-moth or the white-lined sphinx, hover in midair while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds. This hovering capability is only known to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaly-tailed Squirrel
The Anomaluridae are a family of rodents found in central Africa. They are known as anomalures or scaly-tailed squirrels. The six extant species are classified into two genera. All anomalurids have membranes between their front and hind legs like those of a flying squirrel, but they are not closely related to the flying squirrels that form the tribe Petauristini of the family Sciuridae. They are distinguished by two rows of pointed, raised scales on the undersides of their tails. The anatomy of their heads is quite different from that of the sciurid flying squirrels. By extending their limbs, anomalures transform themselves into a gliding platform that they control by manipulating the membranes and tail. Most anomalurid species roost during the day in hollow trees, with up to several dozen animals per tree. They are primarily herbivorous, and may travel up to from their roosting tree in search of leaves, flowers, or fruit, although they also eat a small amount of insects. They ...
