Branchiopoda (gill-footed shrimps; phylum Arthropoda, subphylum Crustacea) Diverse class of small, mainly freshwater, filter-feeding crustaceans, all characterized by flattened, leaf-like, trunk appendages in which the coxa bears a flattened epipodite which functions as a gill.
The Branchiopoda includes the Anostraca (fairy shrimps), Notostraca (tadpole shrimps), Conchostraca (clam shrimps), and Cladocera (water fleas).

 Branchiopoda - Wikipedia, the free encyclopedia
A few are well-known, including Artemia (brine shrimp, called Sea-Monkeys when marketed as novelties), and Daphnia, both of which are raised as aquarium food or as interesting pets in and of themselves.
In older classification, the superorder Diplostraca are made up of the two orders Conchostraca and Cladocera.
Newer data suggests that these orders may be artificial (at least in their present state) as some of their members seem to have a paraphyletic origin within the Diplostraca.

Title : PEET: Crustacean Systematics: Monographic Research in the L eptostraca, Conchostraca, and Brachyura Abstract : 9978193 Martin and Jacobs Although third in number of species (behind insects and molluscs), crustaceans are the most morphologically diverse group of animals on earth.
The Conchostraca (clam shrimp) are members of the class Branchiopoda, an ancient and presumed primitive lineage extending back to the middle Cambrian; all are restricted to freshwater ephemeral pond habitats and are thus species of special conservation concern.
Trainees will become well versed in database management and web site development via formal coursework at UCLA and through the construction of their own monograph web pages; each student will oversee the creation of a relational database that will be posted on the web.

 NHMLC PEET Project: What are conchostracans?
They are often divided by workers into the "cladocerans" (sometimes treated as the order Cladocera; see Martin and Davis, 2001, for discussions on the classification of the cladoceran groups) and the non-cladoceran "large branchiopods." This artificial division is unfortunate.
It masks the large size that some cladocerans can attain, as well as giving the impression that the "large branchiopods" (traditionally, the orders Anostraca, Notostraca, and Conchostraca) are somehow more closely related to each other than they are to any of the cladoceran groups.
The truth is that relationships within the Branchiopoda are still poorly understood, and division of the group into "large branchiopods" and smaller ones (cladocerans) is an obviously artificial grouping of convenience by those who work on the groups.

 CSIRO PUBLISHING - Australian Journal of Zoology
The larval development of L. stanleyana is typical of Conchostraca.
The larval development of the Notostraca differs from that of Conchostraca and Anostraca only in ways related to increased lecithotrophy, metamorphosis being attained more directly.
A primitive mode of development can be identified for the Branchiopoda and interpreted as a derived form of the developmental pattern of the Cephalocarida.

Conchostraca filtrieren ihre Nahrung entweder aus dem Wasser oder aus dem aufgewirbelten Schlamm.
Also belonging to the Branchiopoda, the Cladocera ("water fleas") are a sister group of concostracans, but not considered to be "primeval shrimps", as they possess numerous "modern" characters.

Members of the three crustacean classes Cladocera, Ostracoda and Conchostraca have a bivalved carapace covering the whole body.
The Conchostraca (clam shrimps) are small to medium size (up to 25mm), generally green, green-blue or brown,and often translucent.
The carapace is generally translucent and may be notched in outline and/or carry complex patterns of knobs, pores or hairs.

Conchostraca are placed along with the orders Notostraca, Anostraca and Cladocera in the class Branchiopoda, a name which refers to the foliose trunk appendages which function as gills.
In Conchostraca the body is completely encased in a hinged, bivalved carapace.
The antennules are one-branched (uniramous), often only one-segmented, and do not protrude from the carapace.

 Introduction to Branchiopoda
There are also two fossil groups that belong to the Branchiopoda, but it is unresolved whether they are subgroups within the living groups or evolved separately.
The few cladoceran groups that occur in marine habitats are very different, having huge eyes and instead of being filter feeders like most of their freshwater relatives are active predators.
The Conchostraca or "clam shrimps" differ from the Cladocera in three primary ways: 1) They have appendages along the entire thorax/abdomen whereas the appendages are found only on the anterior segments of cladocerans.

 Jesper Stenderup
One major problem I am addressing is the phylogenetic position of the monotypic Cyclestheria hislopi within the Diplostraca.
This enigmatic species has traditionally been placed within Spinicaudata (Conchostraca) but recent evidence from both morphological and molecular data indicates that the Conchostraca are paraphyletic and that C. hislopi is more closely related to the Cladocerans and therefore outside the Spinicaudata.
This would leave not only the "Conchostraca" (= Laevicaudata + Spinicaudata + Cyclestherida) but also the Spinicaudata as paraphyletic taxa.

It also shows some similarities in terms of its head morphology with the Onychura (the other phyllopod group that includes the Water Fleas or Cladocera and the Clam Shrimps or Conchostraca).
For reviews of these other branchiopods and their relationships refer to Walossek (1993, 1995).
Although track-ways attributed to similar animals are known from the Lower Devonian, until now the earliest known fossil Calmanostraca have been recorded from the Carboniferous.

Formerly, four extant orders were recognized: Anostraca, Notostraca, Conchostraca, and Cladocera, the first two of which are well defined.
The Conchostraca consist of two groups which, although superficially similar, differ in so many fundamental features that they have been placed in separate orders, Laevicaudata and Spinicaudata.
The Cladocera are in fact a heterogeneous assemblage of organisms that have now been split into four orders: Anomopoda, Ctenopoda, Onychopoda, and Haplopoda.

However, the Australian Museum crustacean collection contains shrimp found in temporary pools near the summit of Uluru (Ayers Rock), 360 m above the Gibson Desert of central Australia.
The crustaceans found at Uluru are commonly known as fairy or brine shrimp (Anostraca), shield or tadpole shrimp (Notostraca) and clam shrimp (Conchostraca).
Branchiopoda means 'gill foot' and refers to structures on the animals' limbs through which they breathe.
