Argasidae
The Argasidae are the family of soft ticks, one of the three families of ticks. The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. The currently accepted genera are '' Antricola'', '' Argas'', '' Nothoaspis'', ''Ornithodoros'', and '' Otobius''. The Argasidae are very common in South Asia, along with 96 other species of ticks, making South Asia the region with the highest biodiversity of ticks worldwide. Soft ticks are resistant to desiccation and can live for several years in arid conditions. Physical characteristics Soft ticks lack the hard scutum present in the hard ticks (Ixodidae). The gnathosoma (or capitulum, the mouthparts-bearing structure) is located on the underside of the animal's body and is not readily visible, while in the Ixodidae, the gnathosoma projects forward from the body. The lateral edges of the body are rounded. See also *Ticks of domestic animals Ticks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chillán
Chillán () is the capital city of the Ñuble Region in the Diguillín Province of Chile located about south of the country's capital, Santiago, near the geographical center of the country. It is the capital of the new Ñuble Region since 6 September 2015. Within the city are a railway station, an inter-city bus terminal, an agricultural extension of the University of Concepción, and a regimental military base. The city includes a modern-style enclosed shopping mall in addition to the multi-block open-air street market where fruits, vegetables, crafts and clothing are sold. The nearby mountains are a popular destination for skiing and hot spring bathing.

Animals Described In 2003
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 and ...
