Agnostida is an order of arthropod which first developed near the end of the Early Cambrian period and thrived during the Middle Cambrian. They are present in the Lower Cambrian fossil record along with trilobites from the Redlichiida, Corynexochida, and Ptychopariida orders. The last agnostids went extinct in the Late Ordovician.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms.
Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are also known 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 6–25 mm (0.24–0.98 in) long. Most species have 20 body segments, bearing 11 pairs of leaf-like phyllopodia, 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.
Eucarida is a superorder of the Malacostraca, a class of the crustacean subphylum, comprising the decapods, krill, Amphionides and Angustidontida. They are characterised by having the carapace fused to all thoracic segments, and by the possession of stalked eyes.
Frederick Robert Schram is an American palaeontologist and carcinologist. He received his B.S. in biology from Loyola University Chicago in 1965, and a Ph.D. on palaeozoology from the University of Chicago in 1968 .
Simaethistoidea is an obscure superfamily of pyralid-like moths with two genera, whose biology and relationships among the Ditrysia is currently unknown, namely the Australian Metaprotus and the China and North Indian Simaethistis.
Nepticuloidea is a superfamily of usually very small monotrysian moths that are characterised by small or large eyecaps over the compound eyes. It comprises two families, the "pigmy moths" (Nepticulidae), with 12 genera which are very diverse worldwide and are usually leaf miners, and the "white eyecap moths" (Opostegidae), also worldwide but with five genera and about a ninth as many species, whose biology is less well known.
Lophocoronoidea is a superfamily of insects in the order Lepidoptera. There is a single genus, Lophocorona, in the family Lophocoronidae. These are small, primitive nocturnal moths restricted to Australia whose biology is largely unknown.
The Hepialoidea are the superfamily of "ghost moths" and "swift moths".
Australian Systematic Botany is an international peer-reviewed scientific journal published by CSIRO Publishing. It is devoted to publishing original research, and sometimes review articles, on topics related to systematic botany, such as biogeography, taxonomy and evolution. The journal is broad in scope, covering all plant, algal and fungal groups, including fossils.
Edriophthalma is a disused peracarid (Malacostraca) classification comprising Isopoda and Amphipoda, first proposed by William Elford Leach in 1815. They have several common features, such as the fact that they both lack a carapace, possess sessile compound eyes, and thoracic coxae fused to their pleurites. Some molecular studies have shown that these are not related. The group has also been known as Acaridea and Arthrostraca.
Praegmelina is an extinct genus of crustacean in the order Amphipoda. It existed during the middle Miocene period.
Branchinecta gaini is a species of fairy shrimp from Antarctica and Patagonia. It is the largest freshwater invertebrate in Antarctica, at 16 mm (0.63 in) long. It lives on bacteria and other organisms, surviving the winter as resting eggs.
Calliasmata pholidota is a shrimp of the family Hippolytidae. It is thought C. pholidota is an opportunistic feeder, taking live prey or scavenging for food.
Crustaceans form a large, diverse arthropod taxon which includes such animals as crabs, lobsters, crayfish, shrimps, prawns, krill, woodlice, and barnacles. The crustacean group can be treated as a subphylum under the clade Mandibulata; because of recent molecular studies it is now well accepted that the crustacean group is paraphyletic, and comprises all animals in the clade Pancrustacea other than hexapods. Some crustaceans are more closely related to insects and the other hexapods than they are to certain other crustaceans.
