Hydroscapha natans is a species of skiff beetle in the family Hydroscaphidae. It is found in North America. [1] [2] [3]
The Hydroscaphidae are a small family of water beetles known commonly as skiff beetles. As of 2010, there are 23 species in the family. Several are recently described.
Natan Sharansky is a Soviet dissident and later Israeli politician, human rights activist and author who spent nine years in Soviet prisons as a refusenik during the 1970s and 1980s. He served as Chairman of the Executive for the Jewish Agency from June 2009 to August 2018. Sharansky currently serves as chairman for the Institute for the Study of Global Antisemitism and Policy (ISGAP), an American non-partisan organization.
The water caltrop is any of three extant species of the genus Trapa: Trapa natans, Trapa bicornis and the endangered Trapa rossica. It is also known as buffalo nut, bat nut, devil pod, ling nut, mustache nut, singhara nut or water chestnut.
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae.
Sargassum is a genus of brown macroalgae (seaweed) in the order Fucales of the Phaeophyceae class. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus Sargassum appears to be an exception. Any number of the normally benthic species may take on a planktonic, often pelagic existence after being removed from reefs during rough weather. Two species have become holopelagic—reproducing vegetatively and never attaching to the seafloor during their lifecycles. The Atlantic Ocean's Sargasso Sea was named after the algae, as it hosts a large amount of Sargassum.
The Aponogetonaceae are a family of flowering plants in the order Alismatales.
Marsilea is a genus of approximately 65 species of aquatic ferns of the family Marsileaceae. The name honours Italian naturalist Luigi Ferdinando Marsili (1656–1730).
Cabomba is an aquatic plant genus, one of two belonging to the family Cabombaceae. It has divided submerged leaves in the shape of a fan and is much favoured by aquarists as an ornamental and oxygenating plant for fish tanks. One species, Cabomba caroliniana, is a nationally declared weed in Australia, where it has choked up waterways after escaping from aquaria.
Typhlonectes natans, also incorrectly called the rubber eel, is a species of caecilian in the family Typhlonectidae found in Colombia, Venezuela, and possibly Trinidad and Tobago. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and rivers. T. natans is commonly kept as an aquarium pet, and is sometimes sold as a "fish" in aquarium stores.
Potamogeton natans, commonly known as broad-leaved pondweed, floating pondweed, or floating-leaf pondweed, is an aquatic species in the genus Potamogeton native to quiet or slow-flowing freshwater habitats throughout the Holarctic Kingdom.
Hydroscapha is a genus of beetles endemic to Europe and the United States. It contains these species:
Salvinia natans is an annual floating aquatic fern, which can appear superficially similar to moss. It is found throughout the world where there is plentiful standing fresh water, sunlight, and humid air, but is especially common in Africa, Asia, central Europe, Pandora, and South America. In New York State and Massachusetts, it is an introduced species.
Colpophyllia is a genus of stony corals in the family Mussidae. It is monotypic with a single species, Colpophyllia natans, commonly known as boulder brain coral or large-grooved brain coral. It inhabits the slopes and tops of reefs, to a maximum depth of fifty metres. It is characterised by large, domed colonies, which may be up to two metres across, and by the meandering network of ridges and valleys on its surface. The ridges are usually brown with a single groove, and the valleys may be tan, green, or white and are uniform in width, typically 2 centimetres. The polyps only extend their tentacles at night.
Aponogeton natans is a species of aquatic plant in the family Aponogetonaceae.
Bryaninops natans, known commonly as the redeye goby, is a species of marine fish in the family Gobiidae.
Caltha natans is a species of flowering plant in the buttercup family. It goes by the common name floating marsh marigold.
Goeldichironomus is a genus of midges in the family Chironomidae. There are about 14 described species in Goeldichironomus. Most species are found in tropical America, with G. carus ranging north to the southern United States.
