List Of Non-marine Molluscs Of The Netherlands
This list of non-marine molluscs of the Netherlands is a list of all molluscs other than the marine (salt water) species that live in the Netherlands. This list comprises land snails and slugs, freshwater snails and freshwater clams and mussels. There are 197 non-marine mollusc species living in natural habitats in the Netherlands. There are 169 gastropod (snail and slug) species (52 freshwater and 117 land species), and 28 freshwater bivalve (clams and mussel) species living in the wild. As for introduced species, there are 23 introduced gastropod species (2 freshwater and 21 land species plus '' Candidula unifasciata'' as possibly non-indigenous one), and 4 bivalve species, living in natural habitats in the Netherlands. A total of 5 freshwater non-indigenous species live in natural habitats. Summary table of number of species There are 4 locally extinct species in the Netherlands: the marine gastropod '' Rissoa membranacea'', land gastropod '' Spermodea lamellata'', and ...

Endemic (ecology)
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potamopyrgus Antipodarum
The New Zealand mud snail (''Potamopyrgus antipodarum'') is a species of very small freshwater snail with a gill and an operculum. This aquatic gastropod mollusk is in the family Tateidae. It is native to New Zealand, where it is found throughout the country, but it has been introduced to many other countries, where it is often considered an invasive species because populations of the snail can reach very high densities. Shell description The shell of ''Potamopyrgus antipodarum'' is elongated and has dextral coiling, with 7 to 8 whorls. Between whorls are deep grooves. Shell colors vary from gray and dark brown to light brown. The average height of the shell is approximately 5 mm (\begin \frac \end in); maximum size is approximately 12 mm (\begin \frac \end in). The snail is usually 4–6 mm in length in the Great Lakes, but grows to 12 mm in its native range. It is an operculate snail, with a 'lid' that can seal the opening of its shell. Th ...

Melanoides Tuberculata
The red-rimmed melania (''Melanoides tuberculata''), also known as Malayan livebearing snails or Malayan/Malaysian trumpet snails (often abbreviated to MTS) by aquarists, is a species of freshwater snail with an operculum, a parthenogenetic, aquatic gastropod mollusk in the family Thiaridae. The common name comes from the presence of reddish spots on the otherwise greenish-brown shell. The species name is sometimes spelled ''Melanoides tuberculatus'', but this is incorrect because ''Melanoides'' Olivier, 1804 was clearly intended to be feminine because it was combined with the feminine specific epithet ''fasciolata'' in the original description."Genus: ''Melanoides''" ''Molluscs of central Europe'', accessed 19 April 2011.

Viviparus Viviparus
''Viviparus viviparus'' is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Viviparidae, the river snails. This species is a viviparous ( ovoviviparous) snail. Description The height of the shell is 25–35 mm. The width of the shell is 20–26 mm. Males are 2 mm smaller than females of the same age. The shell colour is dark greenish brown or greyish yellow, with three reddish brown spiral bands. The shell is striated but has no hammer pattern. The shell apex is blunt (more pointed in other ''Viviparus'' species). The shell has 5.5-6 weakly convex whorls. The last whorl is relatively large compared to that of other ''Viviparus'' species. The umbilicus is narrow. The animal can lock itself in behind a round lid which shows concentric striations (the operculum). This allows it to protect itself from dehydration, for several months if necessary. Once closed the operculum is flush with the opening of the ...
