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, with the exception of '' Branchinecta gigas,'' or "giant fairy shrimp", which is itself a predator of other species of anostracans. 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, ...

Branchiopoda
Branchiopoda, from Ancient Greek βράγχια (''bránkhia''), meaning "gill", and πούς (''poús''), meaning "foot", is a class (biology), class of crustaceans. It comprises Anostraca, fairy shrimp, clam shrimp, Diplostraca (or Cladocera), Notostraca, the Devonian ''Lepidocaris'' and possibly the Cambrian ''Rehbachiella''. 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 arthropod mouthparts, mouthparts. This is also responsible for the name of the group (from the , gills, akin to , windpipe; , 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 and clam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branchinecta Gigas
''Branchinecta gigas'' is a species of fairy shrimp that lives in western Canada and the United States. It is the largest species of fairy shrimp, growing up to long. It is known commonly as the giant fairy shrimp. Description Females reach sexual maturity when they are long, and grow up to long; males reach only . Unpublished records exist of individuals up to long. Despite being the largest species, ''B. gigas'' has the proportionally smallest eyes of any species in the family, and possibly in all Anostraca. Distribution ''Branchinecta gigas'' has been found in Alberta, Saskatchewan, Washington, Montana, Oregon, North Dakota, Utah, Nevada and California. A related species, '' B. raptor'', occurs in Idaho. Ecology and behaviour ''B. gigas'' lives in hypersaline lakes and rivers, with salinity ranging from 1.8‰ to 5.8‰. These waters often have high turbidity (low visibility), and so ''B. gigas'' hunts by touch rather than by sight. When feeding, ''B. gigas'' adopts a "hu ...

Brine Shrimp
''Artemia'' is a genus of aquatic crustaceans also known as brine shrimp or ''Sea-Monkeys, sea monkeys''. It is the only genus in the Family (biology), family Artemiidae. The first historical record of the existence of ''Artemia'' dates back to the first half of the 10th century AD from Lake Urmia, Iran, with an example called by an Iranian geographer an "aquatic dog", although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. ''Artemia'' populations are found worldwide, typically in inland saltwater lakes, but occasionally in oceans. ''Artemia'' are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the ''Artemia'' to produce dormant eggs, known as Microbial cyst, cysts, has led to extensive use of ''Artemia'' in aquaculture. The cysts may be stored indefinitely and hatched on demand to provide a convenient for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artemia Salina
''Artemia salina'' is a species of brine shrimp – aquatic crustaceans that are more closely related to '' Triops'' and cladocerans than to true shrimp. It belongs to a lineage that does not appear to have changed much in . ''Artemia salina'' is native to saline lakes, ponds, and temporary waters (not seas) in the Mediterranean region of Southern Europe, Anatolia, and Northern Africa. Considerable taxonomic confusion exists, and some populations elsewhere have formerly been referred to as this species, but are now recognized as separate species. Description ''Artemia salina'' has three eyes and 11 pairs of legs and can grow to about in size. Its blood contains the pigment hemoglobin, which is also found in vertebrates. Males differ from females by having their second antennae markedly enlarged, and modified into clasping organs used in mating. Life cycle Males have two reproductive organs. Prior to copulation, the male clasps the female with his clasping organ, assuming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vernal Pool
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. Certain tropical fish lineages (such as killifishes) have however adapted to this habitat specifically. Vernal pools are a type of wetland. They can be surrounded by many communities/species including deciduous forest, grassland, lodgepole pine forest, blue oak woodland, sagebrush steppe, succulent coastal scrub and prairie. These pools are characteristic of Mediterranean climates, but occur in many other ecosystems. Generation and annual development During most years, a vernal pool basin will experience inundation from rain/precipitation, followed by desiccation from evapotranspiration. These conditions are commonly associated w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
