This website contains a checklist of the described species of millipedes native to Australia. It is a resource for taxonomists, not an identification guide. It does not contain identification keys or pictures. There are more than 400 native species in this checklist. Under each genus and species name there are all the works that might be recommendable to read. This website has as well an interactive maps page for species distributions. ...

GBIF Evertebrata III stellt ein Teilprojekt (oder sog. "Knoten") der Initiative Global Biodiversity Information Facility (= GBIF) Deutschland dar und erfasst als Teilknoten vor allem die Gruppe der marinen Evertebraten. GBIF hat sich zum Ziel gesetzt, alle Informationen zur biologischen Vielfalt, die in Deutschland verfügbar sind, unter einem Dach zu bündeln und über ihre Einstiegsseiten zu erschließen. Die Webseite verweist vor allem auf die Teilprojekte verschiedener Forschungsinstitute wie z.B. das Forschungsinstitut Senckenberg und zahlreiche Typensammlungen anderer Einrichtungen. ...

Diese Webseite liefert Informationen über limnische Wirbellose. Die Darstellungen beschränken sich auf Crustacea (Krebstiere) und Gastropoda (Schnecken). Für diese stehen eine Artendatenbank sowie einzelne Artikel zur Verfügung. Einträge in der Artendatenbank geben Auskunft über mehrere Aspekte der Arten (z.B. Morphologie, Ernährung und Verbreitung). In einzelnen Artikeln finden sich weiterführende Informationen (z.B. zur Biologie und Bestimmung). ... [Redaktion vifabio]
The Website provides taxonomic descriptions and notes on habitat and distribution of crustacean members of the macrobenthos of the North Sea. [Information of the supplier, modified]
Beside a broad introduction to marine lobsters, there are the following suggetions for each species: diagnosis, types, distribution, habitat, biology, size and fishery importance. A online key allows there determination. A comprehensive literature list and a glossary are available. Further information concerns higer taxa (e.g. Metazoa, Bilateria, Crustacea). ...

This shall be the future home of Peracarida where participants will edit and maintain their classification, upload images, maintain bibliographic resources, among other activities. The new Administrator of this site and his or her team of contributors will soon make this their home, so please visit often. [Information of the supplier]
Ostracoda are amazing animals, which inhabit virtually all aquatic environments on Earth. From tropical sand beaches to the deep sea. From the Arctic to Antarctica. From freshwater temporary ponds to acid lakes. They are very special because they present one of the most extensive fossil records including the last 425 millions years! Because of this, ostracods tell us a lot about the history of our planet, including the many climatic changes. ... [Information of the supplier]
Squat lobsters of the superfamilies Chirostyloidea and Galatheoidea are highly visible crustaceans on seamounts, continental margins, shelf environments, hydrothermal vents and coral reefs. About 1000 species are known. They frequently feature in deep-sea images taken by submersibles and are caught in large numbers by benthic dredges. Some species are so locally abundant that they form ‘red tides’. Others support a variety of important fisheries. ... [Information of the supplier]
The Trilobita is an impressively diverse extinct clade, familiar to schoolchildren and scientists alike, that captures the imagination for both aesthetic and scientific reasons. Their 300 million year history, deployed across perhaps 10,000 species, combined with a complex anatomy that can be coded for a broad array of quantitative and qualitative characters, has made them model citizens for applying phylogenetic methods to fossil organisms. Indeed, trilobites figured prominently in some of the earliest forays into cladistic analysis on American shores. One noteworthy aspect of phylogenetic studies incorporating trilobites is that they have not only been used to adduce questions about the nature of macroevolutionary patterns. They have also figured in studies about the processes that may have motivated these patterns. For instance, punctuated equilibria was developed based on information from trilobite phylogenies. Trilobite phylogenies have been used to explore how rates of evolution vary throughout the history of life, and consider the meaning of disparity and how it varies over evolutionary time and during the Cambrian radiation. They have also served as the basis for studies of the mechanisms of evolutionary radiations and mass extinctions. In addition, phylogenetic analyses of trilobites have served as the essential component data of various paleobiogeographic studies. Finally, they have even played a role in testing hypotheses in the burgeoning new field of evo-devo. During the last 20 years trilobite workers have made major strides towards reconstructing the trilobite “tree of life”. Prominent questions certainly still exist, paraphyletic groups like “Ptychopariida” continue to be a messy problem, and some orders are basically unknown from a phylogenetic perspective, yet significant progress has been made. We suspect that phylogenetic analyses of trilobites will continue apace. Some of these will take the form of studies that try to tease apart in greater detail ordinal and familial relationships. Others will focus on species-level phylogenies to gain insight not only into the nature of evolutionary patterns but also the processes that may generate these patterns. Moreover, detailed phylogenetic work at the species-level will be critical for unraveling the higher-level relationships among trilobites as many genera are undoubtedly not monophyletic. We find it encouraging and also salutary that such long extinct organisms can continue to capture the public’s imagination and spur scientific research. Once an evolutionary success story, they now serve as a potential model of how to integrate fossils and phylogeny in the service of shedding light on evolutionary patterns and processes. Here we present a classification of trilobites with a focus on groups that have been treated in phylogenetic studies. We present the classification and phylogenies herein not as the final word on evolutionary relationships, and readers are of course referred to the references in the bibliography for greater details. Instead, they are offered as a framework to build on for future studies and a unified resource and synthesis of what is available regarding cladistic studies of trilobites. ...

Our goal is to understand the relationships of sphaeromatid genera, identify generic and subfamilial groupings and develop phylogenetic hypotheses that can provide a sound basis for future biogeographic, mating-system evolution, ecological, behavioral, and other studies. Our investigation will be guided by morphological and molecular analyses of evolutionary relationships within this family (Crustacea: Isopoda: Sphaeromatidae). ... [Information of the supplier]
