Platyxanthus is a family of crabs, containing the following genera: [1]
The mousebirds are birds in the order Coliiformes. They are the sister group to the clade Eucavitaves, which includes the Leptosomiformes, Trogoniformes (trogons), Bucerotiformes, Piciformes and Coraciformes. This group is now confined to sub-Saharan Africa, and it is the only bird order confined entirely to that continent, with the possible exception of turacos which are considered by some as the distinct order Musophagiformes, and the cuckoo roller, which is the only member of the order Leptosomiformes, and which is found in Madagascar but not mainland Africa. Mousebirds had a wider range in the Paleogene, with a widespread distribution in Europe and North America during the Paleocene.
Henri Milne-Edwards was an eminent French zoologist.
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.
Brain coral is a common name given to various corals in the families Mussidae and Merulinidae, so called due to their generally spheroid shape and grooved surface which resembles a brain. Each head of coral is formed by a colony of genetically identical polyps which secrete a hard skeleton of calcium carbonate; this makes them important coral reef builders like other stony corals in the order Scleractinia. Brain corals are found in shallow warm water coral reefs in all the world's oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or "flower animals". The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height.
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.
Ranina is a genus of crabs belonging to the family Raninidae.
Carpilioidea is a superfamily of crabs containing a single extant family, Carpiliidae and three extinct families. The modern range of the family includes the Indo-Pacific, Western Atlantic and Caribbean Sea. The fossil record of the group extends back at least as far as the Paleocene.
The Caryophylliidae are a family of stony corals found from the tropics to temperate seas, and from shallow to very deep water.
Palaelodidae is a family of extinct birds in the group Phoenicopteriformes, which today is represented only by the flamingos. They have been described as "swimming flamingos."
Milne-Edwards's sifaka, or Milne-Edwards's simpona, is a large arboreal, diurnal lemur endemic to the eastern coastal rainforest of Madagascar. Milne-Edwards's sifaka is characterized by a black body with a light-colored "saddle" on the lower part of its back. It is closely related to the diademed sifaka, and was until recently considered a subspecies of it. Like all sifakas, it is a primate in the family Indriidae.
Astrocoeniidae is a family of stony corals. The family is distributed across the tropical and subtropical oceans worldwide.
Platyxanthus crenulatus is a species of crab in the family Platyxanthidae. The species is found along the sublittoral zone of the western Atlantic in the waters of Brazil, Uruguay and Argentina, associated mostly with hard bottoms. Adults are robust and conspicuous crabs, with a smooth carapace, dorsally purple and white ventrally. Their claws have marked heterochely and right-handedness, traits associated with shell-breaking feeding habits. Due to its abundance, large size and diet, P. crenulatus presumably has an important ecological role as a predator in benthic communities.
Platyxanthus is a genus of crabs in the family Platyxanthidae, containing the following species:
Dendrophylliidae is a family of stony corals. Most members are azooxanthellate and thus have to capture food with their tentacles instead of relying on photosynthesis to produce their food. The World Register of Marine Species includes these genera in the family:
Stylaster is a genus of hydroids in the family Stylasteridae.
Merulinidae is a family of reef-building stony corals.
Heterocyathus is a genus of coral of the family Caryophylliidae.
Stomatopora is a genus of bryozoans belonging to the family Stomatoporidae.
