Alphonse Milne-Edwards was a French mammalogist, ornithologist, and carcinologist. He was English in origin, the son of Henri Milne-Edwards and grandson of Bryan Edwards, a Jamaican planter who settled at Bruges.
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.
Majidae is a family of crabs, comprising around 200 marine species inside 52 genera, with a carapace that is longer than it is broad, and which forms a point at the front. The legs can be very long in some species, leading to the name "spider crab". The exoskeleton is covered with bristles to which the crab attaches algae and other items to act as camouflage.
Palicus is a genus of stilt crabs in the family Palicidae.
The Paguridae are a family of hermit crabs of the order Decapoda. This family contains 542 species in over 70 genera:. The king crabs, Lithodoidea, are now widely undestood to be derived from deep within the Paguridae, with some authors placing their ancestors within the genus Pagurus.
Dromiidae is a family of crabs, often referred to as sponge crabs. They are small or medium-sized crabs which get their name from the ability to shape a living sponge into a portable shelter for themselves. A sponge crab cuts out a fragment from a sponge and trims it to its own shape using its claws. The last two pairs of legs are shorter than other legs and bend upward over the crab's carapace, to hold the sponge in place. The sponge grows along with the crab, providing a consistent shelter.
The Caryophylliidae are a family of stony corals found from the tropics to temperate seas, and from shallow to very deep water.
Munidopsis is a genus of squat lobster. It is the second largest of all the genera of squat lobsters, after Munida, with over 200 species. Its members are mainly found on continental slopes and on abyssal plains. A few fossil species are also known, including specimens from the Campanian (Cretaceous).
Munida is the largest genus of squat lobsters in the family Munididae, with over 240 species.
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.
Macropodia is a genus of crabs, belonging to the family Inachidae. It contains the following species:
Panopeus is a genus of crabs, containing these extant species:
Pisinae is a subfamily of crabs in the family Epialtidae, comprising the following genera:
Around 65 species of crab occur in the waters of the British Isles. All are marine, with the exception of the introduced Chinese mitten crab, Eriocheir sinensis, which occurs in fresh and brackish water. They range in size from the deep-water species Paromola cuvieri, which can reach a claw span of 1.2 metres, to the pea crab, which is only 4 mm (0.16 in) wide and lives inside mussel shells.
Geryonidae is a family of crabs, including the following genera and species:
Rhizangiidae is a family of stony corals in the order Scleractinia. This family is closely related to Oculinidae. Members of this family are non-reef building corals and reproduce from stolons. The corallites are small and the septa are simple.
Chaceon is a crab genus in the family Geryonidae.
Pachycheles is a genus of porcelain crabs in the family Porcellanidae. There are more than 40 described species in Pachycheles.
Cyclodorippidae is a family of crustaceans belonging to the order Decapoda.
Xylopagurus is a genus of hermit crabs within the family Paguridae. There are currently 4 species assigned ot the genus.
