Pycnoclavella
''Pycnoclavella '' is a genus of sea squirts first circumscribed by Walter Garstang in 1891. The generic name comes from the Ancient Greek (''puknós'') meaning "closely united". In 1990, Patricia Kott placed ''Pycnoclavella'' in its own family, Pycnoclavellidae, but in 2008 it was moved back to Clavelinidae. , WoRMS Worms may refer to: *Worm, an invertebrate animal with a tube-like body and no limbs Places *Worms, Germany, a city **Worms (electoral district) *Worms, Nebraska, U.S. *Worms im Veltlintal, the German name for Bormio, Italy Arts and entertainme ... recognizes the following species: * '' Pycnoclavella arenosa'' * '' Pycnoclavella atlantica'' * '' Pycnoclavella aurantia'' * '' Pycnoclavella aurilucens'' * '' Pycnoclavella belizeana'' * '' Pycnoclavella brava'' * '' Pycnoclavella communis'' * '' Pycnoclavella detorta'' * '' Pycnoclavella diminuta'' * '' Pycnoclavella elongata'' * '' Pycnoclavella filamentosa'' * '' Pycnoclavella flava'' * '' Pycno ...

Clavelina Lepadiformis
''Clavelina lepadiformis'', common name the light-bulb sea squirt, is a colonial sea squirt native to the NE Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe .... Distribution This species is a common shallow-water ascidian in Great Britain and Ireland. It occurs from Norway along European coasts south to the Mediterranean.

Aplousobranchia
Aplousobranchia is an order of sea squirts in the class Ascidiacea. They are colonial animals, and are distinguished from other sea squirts by the presence of relatively simple pharyngeal baskets. This provides the etymology of their name: in ancient greek, () means "simple". The posterior part of the abdomen contains the heart and gonads, and is typically larger than in other sea squirts.

Edward Forbes
Edward Forbes FRS, FGS (12 February 1815 – 18 November 1854) was a Manx naturalist. In 1846, he proposed that the distributions of montane plants and animals had been compressed downslope, and some oceanic islands connected to the mainland, during the recent ice age. This mechanism, which was the first natural explanation to explain the distributions of the same species on now-isolated islands and mountain tops, was discovered independently by Charles Darwin, who credited Forbes with the idea. He also incorrectly deduced the so-called azoic hypothesis, that life under the sea would decline to the point that no life forms could exist below a certain depth. Early years Forbes was born at Douglas on the Isle of Man. His father was a well-to-do banker. As a child, Forbes was very interested in collecting insects, shells, minerals, fossils, and plants. Due to poor health, he was unable to attend school from his 5th through his 11th years. In 1828, he started attending the Ath ...

Maurice Caullery
Maurice Jules Gaston Corneille Caullery (5 September 1868, Bergues – 13 July 1958, Paris) was a French biologist. Biography He was born in Bergues in north France on 5 September 1868. His early education was in Douai. He began as a lecturer in zoology at Lyon in 1897. From 1901 to 1903 he was a lecturer at the faculty of sciences in Marseille, and from 1903 to 1909, taught classes at the Sorbonne (laboratory of ''évolution des êtres organisés''). In 1909 he succeeded Alfred Mathieu Giard (1846-1908) as director of the zoological station in Wimereux. In 1923 he opened a new laboratory of ''évolution des êtres organisés'' on Boulevard Raspail in Paris. Maurice Caullery (1868-1958)- biographie - Archives de l'Institut Pasteur Caullery specialised in parasitic protozoans and marine invertebrates. He also worked on insects. His research of ''Siboglinum weberi'' was to become the foundation for establishing the family of beard worms known today as Siboglinidae. Also, he ...

Walter Garstang
Walter Garstang FLS FZS (9 February 1868 – 23 February 1949), a Fellow of Lincoln College, Oxford and Professor of Zoology at the University of Leeds, was one of the first to study the functional biology of marine invertebrate larvae. His best known works on marine larvae were his poems published as ''Larval Forms and Other Zoological Verses'', especially ''The Ballad of the Veliger''. They describe the form and function of several marine larvae as well as illustrating some controversies in evolutionary biology of the time. Garstang was known for his vehement opposition to Ernst Haeckel's Biogenetic Law, now discredited. He is also noted for his hypothesis on chordate evolution, known as Garstang's theory, which suggests an alternative route for chordate evolution from echinoderms. Early life Walter Garstang was born on 9 February 1868 as the eldest son of Dr Walter Garstang of Blackburn and his wife Matilda Mary Wardley, and older brother of the archaeologist John Gars ...

Augustus Addison Gould
Augustus Addison Gould (April 23, 1805 – September 15, 1866) was an American conchologist and malacologist. Biography Born in New Ipswich, New Hampshire, he was the son of music teacher Nathaniel Duren Gould (1781–1864) who was also noted for his penmanship.

Nephtheis
''Nephtheis fascicularis'', commonly called the lollipop tunicate, lollipop coral, or blue palm coral, is a species of tunicate that is native to the shallow reefs of Indonesia. It is the only species in its genus ''Nephtheis''. They are not photosynthetic, and live on plankton and small organic particles obtained from the water currents. The branched stems are formed by tiny polyps called zooid A zooid or zoöid is a single animal that is part of a colonial animal. This lifestyle has been adopted by animals from separate unrelated taxa. Zooids are multicellular; their structure is similar to that of other solitary animals. The zooi ...s.

Eudistoma
''Eudistoma'' is a genus of sea squirts belonging to the class Ascidiacea. It was first described in 1909 by Maurice Caullery. Originally it was thought to be a subgenus of '' Distoma''. ''Eudistoma'' is the most species-rich genus in the family Polycitordae, with 124 valid species as of 2014. They are found in tropical and temperate waters; some species are also found in the Antarctic and subtropical area. Description In 1909 Caullery described ''Eudistoma'' as a subgenus of ''Distoma'' due to the rows of stigmata in the pharynx. In 1917 Ritter and Forsyth described it as a separate genus without explanation. Three subsequent papers published in 1919, 1921 and 1942 all considered it to be a subgenus of ''Polycitor''. ''Eudistoma'' was finally considered a valid genus in 1945 due to "the three rows of pharyngeal slits, long esophagus, flat stomach in the posterior region of the abdomen, very conspicuous longitudinal muscles extending from the pharynx to the end of the abdomen a ...

Sylvanus Charles Thorp Hanley
Sylvanus Charles Thorp Hanley (1819–1899) was a British conchologist and malacologist who published the first book on shells using the then new technique of photography. He authored ''Conchologia indica'' with William Theobald which was a treatise on the shells of British India. The plates were drawn and lithographed by ''George Brettingham Sowerby the younger'', who was well known for writing and illustrating excellent works of natural history, especially conchological works. Sowerby became the best illustrator of conchological works of his time, illustrating such classics as Reeve's monumental twenty-volume ''Conchologia Iconica''. Sylvanus Hanley inherited a fortune, which enabled him to devote a lifetime to conchology. He was especially interested in the bivalves, on which he was a leading authority. He published over 40 books and scientific papers, and described over 200 new species. Hanley collected molluscs extensively; most of his collections are today held at Leeds City ...
