World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Siphonal Canal
The siphonal canal is an anatomical feature of the shells of certain groups of sea snails within the clade Neogastropoda. Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is drawn into the mantle cavity and over the gill and which serves as a chemoreceptor to locate food. Siphonal canals allow for active transport of water to sensory organs inside the shell. Organisms without siphonal canals in their shells rely on passive or diffuse transport or water into their shell. Those with siphonal canals have a direct inhalant stream of water that interacts with sensory organs to detect concentration and direction of a stimulus, such as food or mates. In certain groups of carnivorous snails, where the siphon is particularly long, the structure of the shell has been modified in order to house and protect the soft structure of the siphon. Thus the siphonal canal is a semi-tubular extension of the aperture of the shell th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hermann Strebel (malacologist)
Hermann Wilhelm Strebel ( Hamburg, 1 January 1834 – Hamburg, 6 November 1914) was a merchant, ethnologue and a malacologist from Germany and Mexico. Biography He was born on 1 January 1834 in Hamburg as the youngest of four brothers. Through his school teacher he became interested in the study of snails and their shells On 13 August 1848, he left for Veracruz (city), Veracruz in Mexico. Under the supervision of his eldest brother he became an apprentice in a factory. He would stay in Mexico for the next twenty years. He survived a shipwreck off the coast of Yucatán (peninsula), Yucatán. Between 1852 and 1867 he worked as a merchant for German exporters of manufactured goods. During this time he began under the guidance of his friend Carl Hermann Berendt collecting shells of native snails, which would constitute the basis of his collection. At this time, he began a lively exchange with German and American malacologists. He was also introduced by Berendt to zoology and archeolog ...
