Myxas Glutinosa
''Myxas glutinosa'' (glutinous snail) is a species of small air-breathing freshwater snail, an aquatic gastropod mollusc in the family Lymnaeidae, the pond snails. Anatomy This snail is unusual in that it extends its almost transparent mantle to completely cover the shell when it is in motion, giving the very small animal a glass-like appearance. It also makes the animal sticky to the touch, hence its common name. Shell Description The shell is 13 to 16 mm in height and 11 mm to 15 mm in width in the adult. The upper whorls are almost flat so that the shell has a short blunt spire, the last whorl is inflated and predominating. The aperture is more than 90% of the shell height. The umbilicus is closed. The shell colour is brown or green, extremely thin and very transparent and shiny. Distribution This species is European: it is now rare in western Europe, and even rarer in eastern Europe. * British Isles - listed in List of endangered species in the British ...

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 ...

Grand Canal (Ireland)
The Grand Canal ( ga, An Chanáil Mhór) is the southernmost of a pair of canals that connect Dublin, in the east of Ireland, with the River Shannon in the west, via Tullamore and a number of other villages and towns, the two canals nearly encircling Dublin's inner city. Its sister canal on the Northside of Dublin is the Royal Canal. The last working cargo barge passed through the Grand Canal in 1960. Branches * Main line from Grand Canal Harbour near St. James's Gate to Shannon Harbour in Co. Offaly. ** Most of the Dublin City section of the route is now used by the Luas. While this section was in use, the canal from Crumlin to the Liffey in Ringsend Basin, which forms part of the current main line, was considered to be a branch. It was a later add-on and was known as the Circular Line. * Naas/Corbally ** Navigable to Naas, but a low bridge prevents access to Corbally * Barrow, joining the River Barrow at Athy * Milltown feeder * The Mountmellick Line, which left the Bar ...

Royal Canal (Ireland)
The Royal Canal ( ga, An Chanáil Ríoga) is a canal originally built for freight and passenger transportation from Dublin to Longford in Ireland. It is one of two canals from Dublin to the River Shannon and was built in direct competition to the Grand Canal. The canal fell into disrepair in the late 20th century, but much of it has since been restored for navigation. The length of the canal to the River Shannon was reopened on 1 October 2010, but a final spur branch, to Longford Town, remains closed. History Construction In 1755, Thomas Williams and John Cooley made a survey to find a suitable route for a man-made waterway across north Leinster from Dublin to the Shannon. They originally planned to use a series of rivers and lakes, including the Boyne, Blackwater, Deel, Yellow, Camlin and Inny and Lough Derravaragh. A disgruntled director of the Grand Canal Company sought support to build a canal from Dublin to Cloondara, on the Shannon in West County Longford. Work on t ...
