Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pale Crag Martin
The pale crag martin (''Ptyonoprogne obsoleta'') is a small passerine bird in the swallow family that is resident in Northern Africa and in Southwestern Asia, east to Pakistan. It breeds mainly in the mountains, but also at lower altitudes, especially in rocky areas and around towns. Unlike most swallows, it is often found far from water. It is long, with mainly brown plumage, paler-toned on the upper breast and underwing Covert feather, coverts, and with white "windows" on the spread tail in flight. The sexes are similar in appearance, but juveniles have pale fringes to the upperparts and flight feathers. It was formerly considered to be the northern subspecies of the rock martin of southern Africa, although it is smaller, paler, and whiter-throated than that species. The pale crag martin hunts along cliff faces for flying insects using a slow flight with much gliding. Its call is a soft twitter. This martin builds a deep bowl nest on a sheltered horizontal surface, or a neat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinonyssidae
Rhinonyssidae is a family of mites in the order Mesostigmata. There are about 16 genera and at least 460 described species in Rhinonyssidae. The mites of this family are obligate parasites of avian respiratory systems, living in nasal passageways. They are endoparasites, typically living their entire life in within the respiratory systems of birds. Rhinonyssid mites are widespread, and have been observed on every continent including Antarctica (''Rhinonyssus sphenisci'', first observed in 1963). Genera These 16 genera belong to the family Rhinonyssidae: * '' Charadrinyssus'' Butenko, 1984 * '' Larinyssus'' Strandtmann, 1948 * '' Locustellonyssus'' Bregetova, 1965 * ''Passeronyssus'' Fain, 1960 * ''Pipronyssus'' Fain & Aitken, 1967 * ''Ptilonyssus'' Berlese & Trouessart, 1889 * ''Rallinyssus'' Strandtmann, 1948 * ''Rhinoecius'' Cooreman, 1946 * ''Rhinonyssus'' Trouessart, 1894 * ''Ruandanyssus'' Fain, 1957 * ''Sternostoma'' Berlese & Trouessart, 1889 * ''Tinaminyssus'' Strandtm ...

Animals Described In 1889
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms ...

Parasitic Acari
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
