Jacforus
''Jacforus cavatus'' is a species of crab in the monotypic genus ''Jacforus'' in the family Xanthidae. Description ''Jacforus'' is a small crab, with a carapace around long and wide. Distribution ''Jacforus cavatus'' has a wide distribution in the tropical Indo-Pacific, ranging from Kenya to Australia, Japan and Hawaii. Taxonomy ''Jacforus cavatus'' was species description, first described by Mary J. Rathbun in 1907 as ''Cycloxanthus cavatus''. It was described again by Charles Howard Edmondson in 1925 as ''Euxanthus minutus'', and again by Edmondson in 1931 as ''Megametope sulcatus'', both of which are junior synonym, junior subjective synonym, subjective (heterotypic) synonyms. The affinites of Rathbun's species with other genera have also been unclear; its apparent affinities with the genus ''Medaeus'' are superficial. When Danièle Guinot split the genus ''Cycloxanthops'' in 1968, creating the new genus ''Neoxanthops'', ''C. cavatus'' was not explicitly placed i ...

Xanthidae
Xanthidae is a family (biology), 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 Tetraodontidae, puffer fish, and may be produced by bacteria in the genus ''Vibrio'' living in symbiosis with the crabs, mostly ''Vibrio alginolyticus, V. alginolyticus'' and ''Vibrio parahaemolyticus, V. parahaemolyticus''. Classification Many species formerly included in the family Xanthidae have since been moved to new families. Despite this, Xanthidae is still the largest crab family in terms of species richness, contanining the following subfamilies and genera: *Actaeinae **''Actaea (crab), Actaea'' **''Actaeodes'' **''Actaeops'' † **''Allactaea'' **''Eoxanthops'' † **''Epiactaea'' **''Epiactaeodes'' **''Forestiana'' **''Gaill ...
