Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts. Linnean taxonomy The taxonomy of this group according to the taxonomy of the Ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Non-marine Molluscs Of Turkey
The non-marine molluscs of the country of Turkey are a part of the molluscan fauna of Turkey. The biodiversity of non-marine molluscs of Turkey is richer than in surrounding European states.Şereflişan H., Yildirim M. Z. & Şereflişan M. (2009). "The gastropod fauna and their abundance, and some physicochemical parameters of Gölbaşı lake, Adıyaman, Lake Gölbaşı (Hatay, Turkey)".

Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

List Of Non-marine Molluscs Of Ireland
This list of the non-marine molluscs of Ireland comprises 165 species of non-marine molluscs which have been recorded as part of the fauna of Ireland. These are terrestrial and aquatic gastropods, and bivalves; the list does not include species of molluscs which are considered to be fully marine. In other words: this list includes land snails and slugs, and freshwater and brackish water snails. It also includes freshwater mussels and freshwater clams, including some that can tolerate brackish water. Molluscs that are fully adapted to live in the sea are not included here. Ireland is an island in the northeastern Atlantic. It consists of the Republic of Ireland, also known simply as Ireland (or in the Irish language ''Éire''), and Northern Ireland, which is part of the United Kingdom. The mollusc fauna of the island of Ireland has not been as thoroughly researched as that of the island of Great Britain, and therefore it is possible that some uncommon and local species (whether ...

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 and Asia from the "New World" of the Americas in the European perception of the World.

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 ...
