Thomas Say was an American entomologist, conchologist, and herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society, and professor of natural history at the University of Pennsylvania.
Leander Club, founded in 1818, is one of the oldest rowing clubs in the world, and the oldest non-academic club. It is based in Remenham in Berkshire, England and adjoins Henley-on-Thames. Only three other surviving clubs were founded prior to Leander: Brasenose College Boat Club and Jesus College Boat Club and Westminster School Boat Club, founded in 1813.
The Leander McCormick Observatory is one of the astronomical observatories operated by the Department of Astronomy of the University of Virginia, and is situated just outside Charlottesville, Virginia (US) in Albemarle County on the summit of Mount Jefferson. It is named for Leander J. McCormick (1819–1900), who provided the funds for the telescope and observatory.
Alpheus is a genus of snapping shrimp of the family Alpheidae. This genus contains in excess of 291 species, making this the most species-rich genus of shrimp. Like other snapping shrimp, the claws of Alpheus are asymmetrical, with one of the claws enlarged for making a popping noise. Some species in the genus enter into symbiotic relationships with gobiid fishes, and others associate with sea anemones. It's also the noisiest of all sea creatures and can immobilize small fish with its high pitched frequency.
Palaemonetes, its common names include glass shrimp, ghost shrimp, feeder shrimp, is a genus of caridean shrimp comprising a geographically diverse group of fresh water, brackish and marine crustaceans. Conventionally, Palaemonetes included the following species:
Palaemonidae is a family of shrimp in the order Decapoda. Many species are carnivores that eat small invertebrates, and can be found in any aquatic habitat except the deep sea. One significant genus is Macrobrachium, which contains commercially fished species. Others inhabit coral reefs, where they associate with certain invertebrates, such as sponges, cnidarians, mollusks, and echinoderms, as cleaner shrimps, parasites, or commensals. They generally feed on detritus, though some are carnivores and hunt tiny animals.
Pleurocera is a genus of freshwater snails with an operculum, aquatic gastropod mollusks in the family Pleuroceridae.
Eonecrophorus tenuicornis is a species of carrion beetle found in eastern Nepal. First described scientifically by Yoshihiko Kurosawa in 1985, E. tenuicornis is the only species in the genus Eonecrophorus.
Rhytidocystis is a genus of apicomplexans. It is the only genus within the monotypic family Rhytidocystidae. The species of this genus are parasitic protozoa found in marine annelids.
Jordanita is a genus of moths of the family Zygaenidae.
Elenchus tenuicornis is an insect species in the genus Elenchus.
Thor is a genus of shrimp, containing the following species:
Solen is a genus of marine bivalves in the family Solenidae.
Veloxidium is a genus of parasitic alveolates in the phylum Apicomplexa. Species in this genus infect marine invertebrates.
Cirolana is a genus of isopod crustaceans.
Thylacodes is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. The species in this genus were previously placed in the genus Serpulorbis.
Exosphaeroma is a genus of marine isopod of the family Sphaeromatidae. This genus is found in shallow ocean waters worldwide. It is notable for being one of the few genera of sphaeromatid to be found in the southern reaches of the Southern Ocean. The greatest diversity of Exosphaeroma occurs in the Southern Hemisphere.
Cylapus is a genus of plant bugs in the family Miridae. There are about 12 described species in Cylapus.
Ceratothoais a genus of isopod ectoparasites of teleost fish, first described by James Dwight Dana in 1852. Infection by Ceratothoa can cause anaemia, lesions, growth retardation, emaciation, and mortality in their fish hosts.
