Eugenius Johann Christoph Esper
Eugenius Johann Christoph Esper (2 June 1742 – 27 July 1810) was a German zoologist and naturalist. Born in Wunsiedel in Bavaria, he was professor of zoology at Erlangen university. Life and work Eugen and his brother Friedrich were introduced to natural history at an early age by their father Friedrich Lorenz Esper, an amateur botanist. Encouraged to abandon his theology course by his professor of botany Casimir Christoph Schmidel (1718–1792) Eugen Esper, instead, took instruction in natural history. He obtained his doctorate of philosophy at the university of Erlangen in 1781 with a thesis entitled ''De varietatibus specierum in naturale productis''. The following year, he started to teach at the university initially as extraordinary professor, a poorly paid position, then in 1797 as the professor of philosophy. He directed the department of natural history in Erlangen from 1805. Thanks to him the university collections of minerals, birds, plants, shells and insects ...

Axinellidae
Axinellidae is a family of sponges in the order Axinellida. This family includes some photo-synthetic sponges that occur throughout the world's coral reefs. They are amongst the more common sponges seen in the aquarium trade but are usually not successful species in captivity and not ones that thrive in the small household tank environment. They are common throughout the Indian Ocean and the Pacific Ocean coral reefs. Species which derive their nutrition from sunlight must stay fairly close to the surface in order for their zooxanthellae to synthesize light into the sugars these sponges use to survive. Genera There are ten genera: * ''Axinella'' Schmidt, 1862 * ''Cymbastela'' Hooper & Bergquist, 1992 * ''Dragmacidon'' Hallmann, 1917 * ''Dragmaxia'' Hallmann, 1916 * ''Ophiraphidites'' Carter, 1876 * ''Pararhaphoxya'' Burton, 1934 * ''Phycopsis (sponge), Phycopsis'' Carter, 1883 * ''Pipestela'' Alvarez, Hooper & van Soest, 2008 * ''Ptilocaulis'' Carter, 1883 * ''Reniochalina'' Lend ...
