Guinothusa [1] is a genus of freshwater crabs, found in South-East Asia.
A fiddler crab, sometimes known as a calling crab, may be any of more than one hundred species of semiterrestrial marine crabs in the family Ocypodidae. A smaller number of ghost crab and mangrove crab species are also found in the family Ocypodidae. This entire group is composed of small crabs, the largest being slightly over two inches (5 cm) across. Fiddler crabs are found along sea beaches and brackish intertidal mud flats, lagoons and swamps. Fiddler crabs are most well known for their sexually dimorphic claws; the males' major claw is much larger than the minor claw, while the females' claws are both the same size.
Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are highly poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus Vibrio living in symbiosis with the crabs, mostly V. alginolyticus and V. parahaemolyticus.
Parthenopidae is a family of crabs, placed in its own superfamily, Parthenopoidea. It comprises nearly 40 genera, divided into two subfamilies, with three genera incertae sedis:
Potamonautes is a genus of African freshwater crabs in the family Potamonautidae. It is both the most widespread and most diverse genus of African freshwater crabs, including more than half the species of this continent. They are found in most freshwater habitats of the African mainland and some species are semi-terrestrial.
The Gecarcinucidae are a family of true freshwater crabs. The family Parathelphusidae is now demoted to the rank of subfamily, as the Parathelphusinae, within the Gecarcinucidae. "Family" Parathelphusidae is now considered as a junior synonym.
Geosesarma is genus of small freshwater or terrestrial crabs, typically less than 10 mm (0.4 in) across the carapace. They live and reproduce on land with the larval stages inside the egg. They are found from India, through Southeast Asia, to the Solomon Islands and Hawaii.
Potamon is a genus of freshwater or semiterrestrial crabs mainly found from Southern Europe through the Middle East, and as far east as north-western India. The only exception is the North African P. algeriense, which also is the only potamid of mainland Africa. Twenty species are currently recognised:. These crabs are omnivores that have a broad ecological tolerance. The adult Potaman reach up to 50 mm in size during their 10-12 year life span.
Pilumnoidea is a superfamily of crabs, whose members were previously included in the Xanthoidea. The three families are unified by the free articulation of all the segments of the male crab's abdomen and by the form of the gonopods. The earliest fossils assigned to this group are of Eocene age.
Inachidae is a family of crabs, containing 39 genera:
Actaea is a genus of crabs in the family Xanthidae, containing the following species:
Pilumnus is a genus of crabs, containing the following species:
Demanietta is a genus of freshwater crabs found in Indochinese Peninsula of Southeast Asia. Most of them are found in fast flowing water habitats, giving their common name "waterfall crabs". The genus contains ten described species:
Indochinamon is a genus of freshwater crabs, typically found in the Indo-China region.
Tiwaripotamon is a genus of freshwater crabs, recorded from China and Vietnam.
Eosamon is a genus of freshwater crabs in the subfamily Potamiscinae, found in East and South-East Asia.
Laevimon is a genus of freshwater crabs, found in Vietnam. Data are deficient concerning their IUCN Red List of Threatened Species status.
Sayamia is a genus of freshwater crabs, found in South-East Asia. Three species are included on the list of least concern (lc) arthropods, but S. melanodactylus is endangered.
Mekhongthelphusa is a genus of freshwater crabs in the family Gecarcinucidae, found in South-East Asia.
Esanthelphusa is a genus of freshwater crabs, found in South-East Asia.
Sayamia germaini is a species of freshwater crabs, now moved from the Parathelphusidae to the subfamily Parathelphusinae, found in Thailand, Cambodia and southern Vietnam. This crab is considered an alien invasive species to Taiwan and is included on the list of least concern arthropods.
