Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, 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 Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Branchiopoda
Branchiopoda is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca (or Cladocera), Notostraca and the Devonian ''Lepidocaris''. They are mostly small, freshwater animals that feed on plankton and detritus. Description Members of the Branchiopoda are unified by the presence of gills on many of the animals' appendages, including some of the mouthparts. This is also responsible for the name of the group (from the grc, βράγχια, gills, akin to , windpipe; el, πούς, foot). They generally possess compound eyes and a carapace, which may be a shell of two valves enclosing the trunk (as in most Cladocera), broad and shallow (as in the Notostraca), or entirely absent (as in the Anostraca). In the groups where the carapace prevents the use of the trunk limbs for swimming (Cladocera, clam shrimp and the extinct Lipostraca), the antennae are used for locomotion, as they are in the nauplius. Male fairy shrimp have an enlarged pair of antennae with which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anostraca
Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are referred to as fairy shrimp. They live in vernal pools and hypersaline lakes across the world, and they have even been found in deserts, ice-covered mountain lakes and Antarctic ice. They are usually long (exceptionally up to ). Most species have 20 body segments, bearing 11 pairs of leaf-like ''phyllopodia'' (swimming legs), and the body lacks a carapace. They swim "upside-down" and feed by filtering organic particles from the water or by scraping algae from surfaces. They are an important food for many birds and fish, and some are cultured and harvested for use as fish food. There are 300 species spread across 8 families. Description The body of a fairy shrimp is elongated and divided into segments. The whole animal is typically long, but one species, '' Branchinecta gigas'' does not reach sexual maturity until it reaches long, and can grow to long. The exoskeleton is thin and ...

Thamnocephalidae
Thamnocephalidae is a family of crustaceans with wide distribution including Western Australia, Southern Africa and South America. It was originally described as a subfamily of Branchipodidae by Alpheus Spring Packard in 1883, and elevated to the rank of family Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Idea ... by Simon in 1886. Six genera are recognised, in two subfamilies: ;Thamnocephalinae *'' Thamnocephalus'' Packard, 1879 *'' Carinophallus'' Rogers, 2006 ;Branchinellinae *'' Dendrocephalus'' Daday, 1908 *'' Phallocryptus'' Birabén, 1951 *'' Spiralifrons'' Dixon, 2010 *'' Branchinella'' Sayce, 1903 References Anostraca Crustacean families Taxa named by Alpheus Spring Packard {{branchiopoda-stub ...

Branchinella
''Branchinella'' is a genus of crustaceans in the family (biology), family Thamnocephalidae. This fairy shrimp genus is found across many parts of the world, but especially western Australia and southern Africa. Several species have small ranges and are threatened by habitat destruction. For example, ''Branchinella latzi, B. latzi'' is only known from south Northern Territory and southwest Queensland, but it has been Local extinction, extirpated from the Uluru region due to water pollution, pollution from urine and faeces of tourists. Selected species ''Branchinella'' includes the following species: * ''Branchinella acacioidea'' Belk & Sissom, 1992 * ''Branchinella affinis'' Linder, 1941 * ''Branchinella alachua'' Dexter, 1953 * ''Branchinella apophysata'' Linder, 1941 * ''Branchinella arborea'' Geddes, 1981 * ''Branchinella australiensis'' (Richters, 1876) * ''Branchinella basispina'' Geddes, 1981 * ''Branchinella buchananensis'' Geddes, 1981 * ''Branchinella chudeaui'' (Dada ...

Eugen Von Daday
Eugen von Daday or Jenő von Daday (1855–1920) was a Romanian professor of zoology in Hungary in the late 19th and early 20th century. Daday was an expert on aquatic invertebrates, particularly crustaceans. Daday collected and identified many species and genera within the borders of the Hungarian empire, and received samples of invertebrates from collectors around the world. After his death in 1920, Daday's collection of crustaceans was acquired by the Hungarian Natural History Museum The Hungarian Natural History Museum ( hu, Magyar Természettudományi Múzeum) in Budapest, dating back to 1802, houses the largest natural history collections of Hungary and the region.

Southern Africa
Southern Africa is the southernmost subregion of the African continent, south of the Congo and Tanzania. The physical location is the large part of Africa to the south of the extensive Congo River basin. Southern Africa is home to a number of river systems; the Zambezi River being the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, the Zambezi River flows over the mighty Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist attraction for the region. Southern Africa includes both subtropical and temperate climates, with the Tropic of Capricorn running through the middle of the region, dividing it into its subtropical and temperate halves. Countries commonly included in Southern Africa include Angola, Botswana, the Comoros, Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namib ...

Sua Pan
The Sua Pan or Sowa Pan is a large natural topographic depression within the Makgadikgadi region of Botswana. It is located near the village of ''Sowa'', whose name means salt in the language of the San. The Sua salt pan is one of three large pans within the Makgadikgadi, the other two being Nxai Pan and Nwetwe Pan. The Sua Pan was first described to the European world by David Livingstone, pursuant to his explorations in this region. Significant archaeological recoveries have been made within the Nwetwe Pan, featuring Stone-Age tools from peoples who lived in this area when a large year-round lake occupied the Sua and Nwetwe Pans. The Brines of Sua Pan being one of the largest playa lakes in the world spans approximately 24000 square kilometers. While sodium chloride is the prime constituent, there are many other salts found within this area such as sodium carbonate, sodium bicarbonate, sodium sulfate, and minor amounts of potassium chloride (potash). Currently, Sua Pan is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
