Bathynectes is a genus of crabs in the family Polybiidae. [1]
William Stimpson was an American scientist. He was interested particularly in marine biology. Stimpson became an important early contributor to the work of the Smithsonian Institution and later, director of the Chicago Academy of Sciences.
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:
Palaemon is a genus of caridean shrimp in the family Palaemonidae.
Herbstia is a genus of crabs, containing the following eleven species:
Epialtinae is a subfamily of crabs, containing the following genera:
The bathyal swimming crab, Bathynectes longispina, is a species of crab in the family Polybiidae.
Osachila is a genus of crabs in the family Aethridae, containing three fossil species, and the following extant species:
Acanthocarpus is a genus of crabs in the family Calappidae, containing the following species:
Leucosiidae is a family of crabs containing three subfamilies and a number of genera incertae sedis:
Micropanope is a genus of crabs in the family Pseudorhombilidae, containing one exclusively fossil species and the following species:
Petrolisthes eriomerus is a species of marine porcelain crab found in the eastern Pacific Ocean. It is commonly known as the flattop crab. It is a flattened, rounded animal, with a carapace up to 20 mm (0.8 in) across. It is a filter feeder, and also sweeps food from rocks.
Stephanasterias albula is a species of starfish in the family Asteriidae. It is the only species in its genus, Stephanasterias, which was described by Verrill in 1871. It has a circumboreal distribution and is found in the north west Atlantic Ocean, the north east Pacific Ocean, the Barents Sea and European waters. It usually has eight arms and is white with a rough upper surface. It has been trawled from depths of 267 metres.
The Panopeidae are a family containing 26 genera of morphologically similar crabs, often known as "mud crabs". Their centers of diversity are the Atlantic Ocean and eastern Pacific Ocean.
Pyromaia cuspidata, also known as the dartnose pear crab, is a species of crab in the family Inachoididae. This crab appears similar to Anasimus latus. It is a long-legged crab with a trident-shaped rostrum, and occurs in Atlantic waters from North Carolina to west Florida, and in the Gulf of Mexico through the Yucatán Peninsula down to Nicaragua. It is also found in Cuban waters. This species lives in depths of 27–549 metres (89–1,801 ft) on bottoms of mud, sand, or pebbles.
Inachoididae is a family of crabs originally erected by James Dwight Dana in 1852. It was not recognised as a valid family until the early 1980s. Its members closely resemble those of the family Inachidae, and the Inachoididae could be recognised as a subfamily of that family.
Pyromaia is a genus of crab in the family Inachoididae, containing the following species:
Mithraculus cinctimanus is a species of crab in the family Majidae. It is found in the Caribbean region and is usually associated with a sea anemone, sponge or coral.
Bathynectes muelleri is an extinct species of polybiid crab and the oldest known species of the genus Bathynectes. It lived in the Central Paratethys of modern-day Ukraine during the Badenian age. While extant species of Bathynectes live mainly in deep water habitats, B. muelleri fossils were found in sediments indicative of shallow water habitats, suggesting the earliest Bathynectes originated in shallow waters, and descendent species migrated to deep-water habitats.
Pseudorhombilidae is a family of crabs.
Palaemon pandaliformis is a species of shrimp of the family Palaemonidae. It is found along with Palaemon northropi.
