	Albert-Auguste Fauvel Albert-Auguste Fauvel (7 November 1851, in Cherbourg-en-Cotentin – 3 November 1909, in Cherbourg) was a French naturalist, known for providing the first detailed description of the Chinese alligator. In 1872 he joined the Chinese Maritime Customs Service in Peking. Later on, he was based in Chefoo, from where he spent several years investigating the natural history of Shantung province. In 1877 he relocated to Shanghai, and in 1882–84 was stationed in Hankou. Afterwards, he served as ''inspecteur des services'' of the Messageries Maritimes ''Messageries Maritimes'' was a French merchant shipping company. It was originally created in 1851 as ''Messageries nationales'', later called ''Messageries impériales'', and from 1871, ''Compagnie des messageries maritimes'', casually known as ... in Paris.

	Rove Beetle The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus ''Leehermania'' proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems. One well-known species is the devil's coach-horse beetle. For some other species, see list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to , with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid i ...

	Stenus ''Stenus'' is a genus of semiaquatic rove beetles in the subfamily Steninae, and one of the largest genus in the kingdom Animalia, with some 2700 known species worldwide (only the beetle genus ''Agrilus'' is comparable in size). They are predators of Collembola and other small arthropods. Adults have a protrusible labium with a sticky tip used in prey capture. To overcome the rapid escape of Collembola, the labium is protruded at high speed (1-3 ms in ''Stenus comma'') by hemolymph pressure, and immediately withdrawn (withdrawn in 30-40 ms in ''Stenus comma''), pulling the prey within the range of the mandibles. However, the labium tip does not easily stick to preys covered in scales or setae or that have a large body size. ''Stenus comma'' is more likely to catch such preys by lunging forward and grabbing them directly with its mandibles rather than using its labium. ''Stenus'' species are also known for "skimming" on the water surface using their pygidial gland secretions that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
