Engaeus Merosetosus
''Engaeus'' is a genus of freshwater crayfish found in Australia, the burrowing crayfishes. Fifteen of the 35 species in the genus occur in Tasmania, where they are known as the Tasmanian land crayfishes. The behaviour of these crayfish is notable as they live in burrows and construct large "chimneys" at the opening. The burrowing crayfish, in the genus ''Engaeus,'' are primarily found in Tasmania with 13 out of 15 species being endemic to the state with the other two species located in Victoria as well as Tasmania. The ''Engaeus'' genus is a highly specialized form of freshwater crayfish which is capable of living in tunnel systems in peaty, muddy or wetland environments with the burrows extending down to the water table (an underground level which defines the transition between water saturated ground and non-saturated ground such as the surface) where the water is generally constant. Description The burrowing crayfish spend their entire life cycle underground in tunnel system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engaeus Urostrictus
The Dandenong Burrowing Crayfish ''(Engaeus urostrictus'') is an Australian freshwater crustacean in the Parastacidae family. As its common name suggests, the Dandenong Burrowing Crayfish is found in the Dandenong Ranges east of Melbourne, Australia. ''Engaeus urostrictus'' is listed as vulnerable on the IUCN Red List of Threatened Species.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
