Hedriocystis Zhadani
Order Desmothoracida, the desmothoracids, are a group of heliozoan protists, usually sessile and found in freshwater environments. The adult is a spherical cell around 10-20 μm in diameter surrounded by a perforated organic lorica, or shell, with many radial pseudopods projecting through the holes to capture food. These are supported by small bundles of microtubules that arise near a point on the nuclear membrane. Unlike other heliozoans, the microtubules are not in any regular geometric array, there does not appear to be a microtubule organizing center, and there is no distinction between the outer and inner cytoplasm. Reproduction takes place by the budding-off of small motile cells, usually with two flagella. Later these are lost, and the pseudopods and lorica are formed. Typically, a single lengthened pseudopod will secrete a hollow stalk that attaches the cell to the substrate. The form of the flagella, the tubular cristae within the mitochondria, and other characters ha ...

Blaschka
Leopold Blaschka (27 May 1822 – 3 July 1895) and his son Rudolf Blaschka (17 June 1857 – 1 May 1939) were glass artists from Dresden, Germany, native to the Bohemian (Czech)–German borderland, and known for the production of biological models such as the glass sea creatures and Harvard University's Glass Flowers. Family background The Blaschka family traces its roots to Josefův Důl (Josefsthal) in the Jizera Mountains, Bohemia, a region known for processing glass, metals, and gems. Members of the Blacschka family had worked in Venice, Bohemia, and Germany. Leopold referred to this history in an 1889 letter to Mary Lee Ware: Born in Český Dub, Bohemia, and one of Joseph Blaschke's three sons, Leopold was apprenticed to a goldsmith and gemcutter in Turnov, a town in the Liberec Region of today's Czech Republic. He then joined the family business, which produced glass ornaments and glass eyes. It was there that Leopold developed a technique which he termed "glass-spi ...
