Tonna (genus)
''Tonna'' is a genus of large sea snails, marine (ocean), 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 (mollusc), spire is short. The outer Lip (gastropod), lip is crenulated and sometimes denticulated throughout its whole length. The oblong Aperture (mollusc), aperture is very large and emarginated inferiorly. The Columella (gastropod), columella is channeled. There is no Operculum (gastropod), operculum. The animal is very large, so as scarcely to be contained within its shell. The head is broad and swollen anteriorly, supporting two long, slender, obtuse, distant tentacles, dilated towar ...

Gastropod Shell
The gastropod shell is part of the body of many gastropods, including snails, 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, ostracum, is typically made of calcium carbonate (CaCO3) precipitated into an organic matrix ...

Body Whorl
The body whorl is part of the morphology (biology), morphology of the gastropod shell, 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 (mollusc), whorl (or revolution) of a spiral or Helix, helical Gastropod shell, shell, terminating in the Aperture (mollusc), 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 Spire (mollusc), spired. The shell of the abalone is a good example of this kind of shell. The opposite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

These are marine invertebrates, marine gastropod molluscs in the clade Littorinimorpha. The name ''tun'' refers to the snails' shell sh ..., the tun shells. 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 mucus which helps it glide across the bottom. Its shell length varies between 30 mm and 145 mm., with its long siphon (for respiration) and tentacles (with eyes at their base) clearly visible. They are known for their thin shells. They are night predators and are usually seen in sandy areas, feeding on bivalve molluscs (clams, oysters, mussels and scallops) and sea cucumbers. Distribution This marine ...

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, but also published a major work on Diptera of Chile. 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 P ...

Lewis Weston Dillwyn
Lewis Weston Dillwyn, FRS (21 August 1778 – 31 August 1855) was a British porcelain manufacturer, naturalist and Whig Member of Parliament (MP). Biography He was born in Walthamstow, Essex, the eldest son of William Dillwyn and Sarah Dillwyn (née Weston). His father, a Pennsylvanian Quaker had returned to Britain in 1777 during Philadelphia's worst period in the American War of Independence and settled at Higham Lodge, Walthamstow, Essex, UK. William Dillwyn was a vociferous anti-slavery campaigner and toured England and South Wales in his work for the Anti-Slavery Committee. William Dillwyn was related to George Haynes through the Emlen and Physick families in Philadelphia and it is likely that the opportunity to buy the Cambrian Pottery in Swansea, Wales, from Haynes came about through these family connections in America. William's letters to his daughter Suzanna are held by the Library Company of Philadelphia and stored at the Historical Society of Pennsylvan ...
