	Lander University \| Triops
		Notostracans differ from anostracans primarily in having a carapace (noto=back, ostrac=shell), sessile compound eyes, and appendages posterior to the genital segments.
		As is true of anostracans, it is difficult to draw exact homologies between the parts of the notostracan limb and that of the ancestral limb.
		The feeding method of notostracans is similar to that proposed for the ancestral crustacean.

		Notostracans (often just called Triops, tadpole shrimp or shield shrimp) are small crustaceans, that are in the Branchiopoda group.
		Notostracans sometimes even cannibalize freshly moulted members of the same species.
		In Austria, two notostracan species (one spring species and one summer species) were documented: Lepidurus apus (Linnaeus, 1758), Triops cancriformis (Bosc, 1801).

	Shrimp - the large food & drink encyclopedia
		Freshwater shrimp available for aquaria include the Japanese marsh shrimp (Caridina japonica) and ghost or glass shrimps (Palaeomonetes sp.) Popular saltwater shrimp include the cleaner shrimp (Lysmata amboinensis), the fire shrimp (Lysmata debelius) and the harlequin shrimp (Hymenocera picta).
		Other more recent and unusual, but very popular freshwater shrimp suitable for Aquariums are Triops longicaudatus or Triops cancriformis (notostracans).
		People that catch shrimp are 'shrimpers', and the act of catching shrimp is called 'shrimping'.

	Notostraca species overview - WikiStuff
		The second major problem with making any definitive statements on the notostracan species is that modern genetic analysis is calling even the agreed species classifications into question.
		With the exception of a few distinct characters such as the supra anal plate on the telson of Lepidurus species, or the presence or absence of the second maxilla amongst various species, their gross anatomy is pretty much the same across the board.
		Not only is there the obvious morphological difference of the supra anal plate, life cycle, general body conformation, chromosome number and genetic analysis indicate these two genera have been separate for much of the triops' history on Earth.

		It is presumed that the Kazacharthrids lived much like their living relatives, in that they were opportunistic omnivores that fed on any available food, from bacterial biofilms to detrius to smaller animals that could be overpowered (i.e., fairy shrimp, small or recently hatched amphibian larvae, smaller members of the same species, etc).
		Fossil evidence suggests that the Kazacharthrans were descended from notostracans that became isolated in bodies of freshwater in Lower Jurassic Kazakhstan.
		The Kazacharthrans were distinguished from the tadpole shrimps in the arrangement of the compound eyes, and the presence of an enlarged telson (the final segment of an arthropod's tail).

		Eggs can stand desiccation and carry populations across the drying out of their habitats (thus you can by them in vials in fish stores to hatch at home to feed resulting naupliar larvae to your pets).
		Notostracans, or tadpole shrimp, are similar to anostracans in their elongate bodies bearing simple phyllopodia, long caudal rami.
		An unusual aspect of notostracans is that abdominal segments are fused into a series of ring-like compound segments, which as a result appear to have multiple pairs of appendages.

	Tadpole Shrimp - Class Notostraca (Site not responding. Last check: 2007-10-14)
		Notostracans, or tadpole shrimp, have a round, flattened shield that covers their head and body, and a forked tail that sticks out the end.
		This tadpole shrimp grows up to 3 cm in length and is found in very temporary ponds, as well as fishless arctic lakes.
		The eggs are carried in a special structure on one pair of their abdominal limbs, called a brood pouch.

		The second antennae become reduced through development, such that they are small or vestigial in adult notostracans.
		The body posterior to the head is relatively undifferentiated, being composed of body rings.
		Notostracans can be found in water bodies ranging from permanent farm dams, ditches etc to very impermanent rain-filled pools, with salinities varying from oligotrophic to modestly saline.

	NHMLC PEET Project: What are conchostracans?
		All conchostracans have a bivalved carapace, with the two valves joined by a dorsal hinge or fold and attached and manipulated by a strong adductor muscle.
		They differ markedly from anostracans and notostracans in their ability to be completely enclosed within the bivalved carapace, and in their correspondingly reduced abdomen.
		Generalizations beyond this point are difficult to make, as the families of clam shrimp are morphologically quite diverse.

		The presence of tadpole shrimp (notostracans), which are highly vulnerable to predation, in this upper portion of the indicates that no fish are upstream of the falls.
		Notostracans, also known as tadpole shrimp, were found only above these barriers.
		As notostracans are normally not found coexisting with predatory fish, their presence supports the assumption that Arctic charr, brook trout or lake trout do not occur in these areas.

	Introduction to Branchiopoda
		The Notostraca are called "tadpole shrimp" because of their broad, plate-like carapace and narrow, elongate thorax/abdomen.
		When populations are very large, Triops, a well known notostracan, can cause considerable damage to rice paddies by burrowing into the sediment and inadvertantly dislodging the young shoots.
		They differ from notostracans by the shape of their carapace, which has elaborate spines on the margin giving them a rather fierce appearance.

		The known range of Triops longicaudatus (Leconte), commonly called tadpole shrimp, is west of Meridian 99 (1).
		The water temperature on 31 October was 17.0 °C, dissolved oxygen was 6.3 mg/L, pH was 6.4, conductivity was 595 µmho/cm, and alkalinity was 108 mg/L. The characteristic habitat of notostracans consists of muddy, alkaline pools which dry completely in the warm months.
		This type of intermittent habitat is usually found in arid or steppe regions (1,4).

		Hundreds of flat impressions of triopsid head shields and some abdominal remains, caudal rami and intact specimens have been excavated, associated with conchostracans, fish and megafloral remains.
		The fossils occur in laminated clayey shale from a 0.5-2 m thick lacustrine bed intercalated in the Coburger Sandstein fluvial channel and floodplain sequence.
		Ichnopodichnus ichnofauna, most likely produced by notostracan branchiopods, also occur in the same locality, but not within the notostracian beds.

		Archival storage includes clear, clean 70 to 75% ethanol, archival-quality glass jars and lids (the best of which now come with polypropylene inserts in the lid), and archival-quality label paper with printed collecting and preservation data.
		Although different groups of crustaceans will vary with regard to the "fields" that are important (e.g., collection depth is not usually an important consideration when dealing with notostracans or terrestrial isopods), the label should a sufficient amount of clearly legible information.
		Avoid at all costs the temptation to include labels bearing only the "station" or "field" number, believing that at some point a future worker will be able to extract the collecting data from your notebook, field journal, or spreadsheet.

		Ephippia and other invertebrate remains were identified, enumerated, and recorded.
		To estimate relative abundance of small invertebrate eggs that were easily missed by hand-sorting (i.e., those of anostracans, conchostracans, notostracans, and ostracods), the remaining 5 soil samples from each wetland were incubated for 8 weeks in 37.8-L glass aquaria filled with water maintained under standardized conditions of light, temperature, and water chemistry described below.
		Many authors have shown that light, temperature, oxygen, and osmotic conditions are the most important factors influencing diapause release and development of resting eggs (e.g.

	Frontiers in Zoology \| Full text \| A review of the correlation of tergites, sternites, and leg pairs in diplopods
		Independent dorsal and ventral segmentation in a similar manner as in Glomeris, and the independent establishment of the tergites, in theory can lead to any combination of tergites with any number of leg pairs.
		If tergite formation and the formation of segments also are not coupled in notostracans, pauropods, and symphylans, this could be the cause for the dorsoventral discrepancies in these arthropods.
		We would like to thank Wolfgang Dohle for stimulating discussions on Glomeris segmentation.
