Tonna (gastropod)
''Tonna'' is a genus of large sea snails, marine gastropod molluscs in the family Tonnidae, the tun or cask shells. WoRMS (2010). Tonna Brunnich, 1771. 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=138557 on 2011-02-23 Description The thin shell is ventricose, inflated, generally globular, rarely oblong and encircled with ribs. The spire is short. The outer lip is crenulated and sometimes denticulated throughout its whole length. The oblong aperture is very large and emarginated inferiorly. The columella is channeled. There is no operculum. The animal is very large, so as scarcely to be contained within its shell. The head is broad, swollen before, supporting two long, slender, obtuse, distant tentacles, dilated towards the base, where the eyes are situated. The mouth is large, muscular, strong and retractile. The respiratory tube is p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Body Whorl
The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the body whorl, or last whorl, is the most recently formed and largest whorl (or revolution) of a spiral or helical shell, terminating in the aperture. It is called the "body whorl" because most of the body of the soft parts of the animal fits into this whorl. The proportional size of the body whorl in gastropod shells differs greatly according to the actual shell morphology. For shells in which the rate of whorl expansion of each revolution around the axis is very high, the aperture and the body whorl are large, and the shell tends to be low spired. The shell of the abalone is a good example of this kind of shell. The opposite tendency can sometimes create a high spire with very little whorl increase per revolution. In these instances, e.g. ...

Lovell Augustus Reeve
Lovell Augustus Reeve (19 April 1814 – 18 November 1865) was an English conchologist and publisher. Life Born at Ludgate Hill, London, on 19 April 1814, he was a son of Thomas Reeve, draper and mercer, by his wife Fanny Lovell. After attending school at Stockwell, he was apprenticed at the age of 13 to Mr. Graham, a local grocer. The chance of purchase of some shells led to a lifelong interest in conchology. In 1833 he attended the meeting of the British Association for the Advancement of Science at Cambridge. At the end of his apprenticeship Reeve paid a visit to Paris, where he read a paper on the classification of Mollusca before the Academy of Sciences. On his return to London, he set to work on his first book, ''Conchologia Systematica'' (2 vols. London, 1841–2). From 1842, he traded as a natural history dealer. Using profits made by the sale of Dutch Governor-General of the Moluccas Van Ryder's collection from the Moluccas, which he purchased at Rotterdam, and with t ...

Description This type of sea snail is distinguished from many others by the fact that its fleshy foot is so much larger than its shell. As with land snails, this gastropod ("stomach-footed") secretes mucous which helps it glide across the bottom. Though this type of snail is sometimes labeled as a "bubble shell" by divers, in fact this animal is a member of the subclass Prosobranchia (snails) as compared to the subclass to which bubble shells belong, Opisthobranchia (bubble shells, sea hares, nudibranchs and others).

Rodolfo Amando Philippi
Rodolfo Amando (or Rudolph Amandus) Philippi (14 September 1808 – 23 July 1904) was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi rumwiede to distinguish him from his grandson "Philippi añados. Early life Philippi was born in Charlottenburg, Berlin to Johann Wilhelm Eberhard Philippi, a Prussian government auditor, and his third wife Maria Anna Krumwiede (m. 1806). The father had five children from two earlier marriages and Philippi was the eldest from the third marriage. In 1818, Philippi, his younger brother Bernhard Eunom (1811–1852) and their mother went to Yverdon-les-Bains, Switzerland, where they were educated at the Pestalozzian Institute founded by Johann Heinrich Pestalozzi (1746–1827).
