Engaewa similis is a species of Australian crayfish in the family Parastacidae.
E. similis is endemic to the Augusta region in Western Australia, and can be found from the Margaret River to the vicinity of Windy Harbour. [3] Although previously considered an endangered species, E. similis is now listed as a species of Least Concern on the IUCN Red List, since it is abundant at the sites where it persists. [3]
An adult female holotype (a single physical example of the species) was found in Augusta, Western Australia by L. P. Smith in 1961. In 1967, E. F. Riek gave detailed description of the holotype, held at the Western Australian Museum; it was 36 millimetres (1.4 in) long (cephalothorax 16.5 mm or 0.65 in), with a blue colour on the chela, and was similar to Engaewa reducta apart from the shape of the rostrum, the structure of the chela and the shape of the telson and uropods.

Tenuibranchiurus is a genus of diminutive freshwater crayfish that live in the Australian state of Queensland. Only one species has been described, the swamp crayfish, T. glypticus.
Orthetrum is a large genus of dragonflies in the Libellulidae family. They are commonly referred to as skimmers.
The Everglades crayfish, sometimes called the Florida crayfish, the blue crayfish, the electric blue crayfish, or the sapphire crayfish, is a species of freshwater crayfish endemic to Florida in the United States. Its natural range is the area east of St. Johns River and all of Florida from Levy County and Marion County southwards, as well as on some of the Florida Keys. It is included on the IUCN Red List as a species of Least Concern. The blue crayfish is frequently kept in a freshwater aquaria. In the wild, this species varies from brown-tan to blue, but an aquarium strain has been selectively bred to achieve a brilliant cobalt blue color.
Engaewa is a genus of burrowing crayfish belonging to the family Parastacidae. There are five recognised species, all endemic to the high-rainfall zone of south-west Western Australia, from Dunsborough to Albany. They are all small, and found only in freshwater swamps and seepages. Three of the five species are listed under the Environment Protection and Biodiversity Conservation Act 1999 and are listed on the IUCN Red List as "endangered" (EN) or "critically endangered" (CR), while the remaining two are listed as "Least Concern":
Euastacus is a genus of freshwater crayfish known as "spiny crayfish". They are found in the south-east of the Australian mainland, along with another genus of crayfish, Cherax. Both genera are members of the family Parastacidae, a family of freshwater crayfish restricted to the Southern Hemisphere.
Cherax quinquecarinatus is a small freshwater crayfish endemic to the south-west corner of Australia. It is one of two species known as gilgie, or jilgi, which is a seasonal food source for people of the region. Gilgies are found throughout a biogeographically isolated region of the coastal south of Western Australia and are significant in the ecology of aquatic systems of that bioregion.
The Maduran leaf-nosed bat is a species of bat in the family Hipposideridae endemic to Indonesia. This species is known from the eastern half of Java and on Madura Island. It is found below 1,000 metres (3,300 ft). It is an IUCN Red List Near Threatened species, with the status changed from Least Concern after a 2021 assessment.
Astacoides is a genus of freshwater crayfish endemic to Madagascar. The first specimens were brought to Europe in 1839, and seven species are now recognised, most of which are considered as threatened on the IUCN Red List. They are large and slow-growing, and are threatened by habitat loss, overexploitation by local people and by spread of introduced non-indigenous marbled crayfish. They are only found in a relatively small part of the island, mostly in undisturbed upland areas. They belong to the Gondwana-distributed family Parastacidae, but their nearest relatives live in Australasia, there being no native crayfish in mainland Africa or India.
Cherax nucifraga is a species of crayfish in the family Parastacidae. It is known only from the type locality – Palm Springs, near Channel Point, Northern Territory, Australia – where the holotype was collected from the stomach of a barramundi. It is listed as data deficient on the IUCN Red List.
Distocambarus is a genus of burrowing crayfish native to Georgia and South Carolina in the United States. It contains five species:
Engaeus australis, the lilly pilly burrowing crayfish, is a species of crayfish in the family Parastacidae. It is endemic to Australia. Engaeus australis is in the Near-threatened status in the International Union for Conservation of Nature(IUCN)'s List.
Engaeus mallacoota, the Mallacoota burrowing crayfish, is a species of crayfish in the family Parastacidae. It is endemic to Australia.
Hobbseus is a genus of crayfish in the family Cambaridae. It comprises seven species, six of which are endemic to Mississippi; H. prominens is the only species to range outside Mississippi, being also found in Alabama. Three of the seven species are listed as endangered (EN) on the IUCN Red List, while three are of uncertain status (DD) and one is of least concern (LC).
Fallicambarus is a genus of crayfish in the family Cambaridae from the United States and Canada. It includes 12 species, of which one is on the IUCN Red List as a vulnerable species (VU) and one as an endangered species (EN). The species of this genus are all restricted to three states or fewer, from Texas and Oklahoma east to Florida.
Cambaroides similis is a species of crayfish endemic to the Korean Peninsula and neighbouring parts of China.
Procambarus natchitochae, or the Red River creek crayfish, is a crayfish native to the Red River basin and Bayou Teche in Texas, Louisiana, and Arkansas. Its distribution is given by the IUCN here, whereas a slightly different Louisiana map is provided in the "Crawfishes of Louisiana", which excludes Bayou Teche P. natchitochae has a distribution of approximately 46,000 km2.
Astacopsis is a genus of crayfish endemic to the island of Tasmania. There are three extant species, Astacopsis gouldi, Astacopsis franklinii, and Astacopsis tricornis. All are threatened by illegal harvesting, and A. gouldi is protected by law. A. franklinii is found in the eastern half of the island, with A. tricornis taking its place in the west. A. gouldi is found only in rivers draining into the Bass Strait, except for the Tamar River.
Euastacus dalagarbe is a species of freshwater crayfish endemic to Australia that belongs to the family Parastacidae. It has a small range in New South Wales and is regarded by the International Union for Conservation of Nature as "critically endangered".
Cherax cainii, known as the smooth marron, is one of two species of crayfish that are endemic in Southwestern Australia known as marron. It occupies a range extending from around Hutt River in the north west to around Esperance in the south east of Western Australia. The species is also now found in variety of artificial and natural fresh water bodies of Queensland, South Australia, Victoria and New South Wales in Australia. It has also been introduced to other countries including North America, Chile, South Africa, Zambia, Japan and New Zealand as a part of commercial aquaculture schemes.
Fallicambarus houstonensis, commonly known as the Houston burrowing crayfish, is a species of crayfish endemic to a select number of counties of southeastern Texas. This species is a primary burrower, as are all other known species of the Fallicambarus genus. Within its limited range, the species lives in abundance. Burrowing crayfish like F. houstonensis tend to thrive in warmer climates with milder and shorter winters. This species lives in semi-terrestrial habitats, sometimes far away from any established bodies of water.
