Anaspidacea
Anaspidacea is an order of crustaceans, comprising eleven genera in four families. Species in the family Anaspididae vary from being strict stygobionts (only living underground) to species living in lakes, streams and moorland pools, and are found only in Tasmania. Koonungidae is found in Tasmania and the south-eastern part of the Australian mainland, where they live in the burrows made by crayfish and in caves. The families Psammaspididae and Stygocarididae are both restricted to caves, but Stygocarididae has a much wider distribution than the other families, with '' Parastygocaris'' having species in New Zealand and South America as well as Australia; two other genera in the family are endemic to South America, and one, '' Stygocarella'', is endemic to New Zealand. Genera *Anaspididae Anaspididae is a family of freshwater crustacean that is endemic to Tasmania, Australia. The family contains 3 genera and 5 species. This group of crustaceans are considered living fossil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucrenonaspides
''Eucrenonaspides oinotheke'' is a species of crustacean in the family Psammaspidae, endemic to Tasmania, the only species described in the genus ''Eucrenonaspides''. The ''Eucrenonaspides'' is a variation of the Anaspidaceans. It was described from a spring at 9 Payton Place, Devonport, Tasmania in 1980, making it "the first spring-dwelling syncarid recorded from the Australian region". It is listed as a vulnerable species on the IUCN Red List. A further undescribed species is known from south-western Tasmania.

Crustaceans
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...
