Jacforus cavatus is a species of crab in the monotypic genus Jacforus in the family Xanthidae.

Contents

Description

Jacforus is a small crab, with a carapace around 5 millimetres (0.20 in) long and 7 mm (0.28 in) wide. [1]

Distribution

Jacforus cavatus has a wide distribution in the tropical Indo-Pacific, ranging from Kenya to Australia, Japan and Hawaii. [1]

Taxonomy

J. cavatus was first described by Mary J. Rathbun in 1907 as Cycloxanthus cavatus. [1] 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 subjective (heterotypic) synonyms. [1] The affinites of Rathbun's species with other genera have also been unclear; [1] its apparent affinities with the genus Medaeus are superficial. [1] When Danièle Guinot split the genus Cycloxanthops in 1968, creating the new genus Neoxanthops , C. cavatus was not explicitly placed in either genus. [1] A new genus, Jacforus, was erected in 2003, commemorating Jacques Forest, [1] and containing only J. cavatus. [2]

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.

Tanaocheles is a genus of crabs, the only genus in the family Tanaocheleidae. It contains two species, T. bidentata and T. stenochilus. The two species were formerly placed in different families, and they were only shown to be related, and placed in a new subfamily, in 2000.

Polydectus cupulifer is a species of crab in the family Xanthidae, and the only species in the genus Polydectus. Together with the genus Lybia, it forms the subfamily Polydectinae. It is found in the Indo-Pacific, ranging from Madagascar and the Red Sea in the west to Japan, Hawaii and French Polynesia in the east. P. cupulifer is densely covered with setae (bristles), and frequently carries a sea anemone in each chela (claw).
