Diaulula Phoca
''Diaulula phoca'' is a species of sea slug or dorid nudibranch, a marine gastropod mollusc in the family Discodorididae.Rosenberg, G. (2010). Diaulula phoca (Ev. Marcus & Er. Marcus, 1967). In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=532733 on 2012-03-01 Taxonomy This species was originally described under the name ''Discodoris phoca'' by Eveline Du Bois-Reymond Marcus and Ernst Gustav Gotthelf Marcus in 1967. It is considered a member of ''Diaulula'' because of the presence of caryophyllidia. Distribution Distribution of ''Diaulula phoca'' includes Florida, Honduras, Costa Rica, Brazil and Panama. The type locality is west side of the Key Biscayne island, Florida. The holotype is stored in the National Museum of Natural History, Smithsonian Institution. Description The body is oval. Mantle is rigid. Dorsum is covered with small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eveline Du Bois-Reymond Marcus
Eveline du Bois-Reymond Marcus (6 October 1901 – 31 January 1990) was a German zoologist and drawer. Life Eveline Du Bois-Reymond was the youngest daughter of Rene and Frieda du Bois-Reymond, as well as a granddaughter of physiologist Emil Du Bois-Reymond. Her father was also a professor of physiology at Berlin University. Her interest in zoology started when she was still a young girl and used to watch small animals in her father's microscope.Corrêa, D.D. (1991) Dr Eveline du Bois-Reymond Marcus. ''Hydrobiologia'', 227: xxiii-xxvi. From 1923 to 1924, she attended zoology courses at the Berlin University, but did not conclude them because she met a professor of zoology, Ernst Marcus and married him. Together, they started a strong collaboration in zoology, including the study of several invertebrate groups, such as protozoans, ctenophores, flatworms, nemertines, annelids, tardigrades, onychophorans, bryozoans, gastropods, and pycnogonids. She was not listed as an author in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caryophyllidia
Caryophyllidia are an anatomical feature of the external dorsal surface of dorid sea slugs. Caryophyllidia are sensory tubercle In anatomy, a tubercle (literally 'small tuber', Latin for 'lump') is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal. In plants A tubercle is generally a wart-like projection ...s, surrounded by tiny needle-like structures called spicules, that are present on the outer mantle.

Gastropods Described In 1967
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
