Egyptian Tomb Bat
The Egyptian tomb bat (''Taphozous perforatus'') is a species of sac-winged bat in the family Emballonuridae. It is a medium- to large-sized Yangochiroptera, microbat with a mass of approximately . It is an aerial insectivore, foraging in open space. Based on individuals captured in Ethiopia, it is thought to feed predominantly on Lepidoptera, but is also known to feed on Isoptera, Coleoptera and Orthoptera. Description Its total body length is , with different subspecies varying in size. Its forearms are long. Its ears are long. Subspecies ''Mammals of Africa'' follows ''Mammal Species of the World'' in recognizing four subspecies. * ''T. p. senegalensis'' — West Africa * ''T. p. perforatus'' — Egypt and northern Sudan * ''T. p. sudani'' — Southern Sudan, South Sudan, eastern Democratic Republic of the Congo, Botswana, and Zimbabwe * ''T. p. haedinus'' — Tanzania through Ethiopia and in South Asia.

Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin des Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactation
Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all sexually mature female mammals, although it may predate mammals. The process of feeding milk in all animals (including humans) is called ''nursing'', and in humans it is also called ''breastfeeding''. Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk. In most species, lactation is a sign that the female has been pregnant at some point in her life, although it can happen without pregnancy. Nearly every species of mammal has nipples; except for monotremes, egg-laying mammals, which instead release milk through ducts in the abdomen. In only one species of mammal, the Dayak fruit bat from Southeast Asia, is milk production a normal male function. ''Galactopoiesis'' is the maintenance of milk production. This stage requires prolactin. Oxytocin is critical for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nycteribiidae
Nycteribiidae is a family of the true fly superfamily Hippoboscoidea are known as "bat flies", together with their close relatives the Streblidae. As the latter do not seem to be a monophyletic group, it is conceivable that bat flies cannot be united into a single family. They are flattened, spiderlike flies without eyes or wings, and as such bear very little resemblance to other Dipterans. These flies are seldom encountered by general collectors, as they almost never leave the bodies of their hosts. Both males and females take blood meals, thus they qualify as real parasites. Most species are highly host-specific. The family is primarily found in the Old World tropics; a few of the 274 known species occur in the Neotropics and in Europe.

Ischnopsyllidae is a family of fleas belonging to the order Siphonaptera Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds.

Xenopsylla Cheopis
The Oriental rat flea (''Xenopsylla cheopis''), also known as the tropical rat flea or the rat flea, is a parasite of rodents, primarily of the genus ''Rattus'', and is a primary vector for bubonic plague and murine typhus. This occurs when a flea that has fed on an infected rodent bites a human, although this flea can live on any warm blooded mammal. Body structure The Oriental rat flea has no genal or pronotal combs. This characteristic can be used to differentiate the Oriental rat flea from the cat flea, dog flea, and other fleas. The flea's body is about one tenth of an inch long (about ). Its body is constructed to make it easier to jump long distances. The flea's body consists of three regions: head, thorax, and abdomen. The head and the thorax have rows of bristles (called combs), and the abdomen consists of eight visible segments. A flea's mouth has two functions: one for squirting saliva or partly digested blood into the bite, and one for sucking up blood from the hos ...

Pulicidae
The Pulicidae are a flea family in the order Siphonaptera. Currently, this family has 181 species in 27 genera. Of these, 16 are known from North America. Like all 2,500 Siphonaptera, the Pulicidae are ectoparasites. These fleas are wingless, laterally flattened, and great jumpers. They must be able to jump quickly and at great relative heights in order to latch onto their host for feeding and for rapid escape from their host. They make incredible jumps using the protein, resilin. It charges the energy in their body, allowing more forceful and frequent jumps than would be possible relying on only their muscles. This also means that they can to jump frequently without exhausting their muscles. They mainly feed on mammal blood, and many Siphonoptera families, including Pulicidae, transmit disease. Ecology Pulicidae feed on mammalian blood. ''Ctenocephalides felis felis'' is also known as the cat flea, and is an extremely important parasite of domestic cats and dogs. They p ...
