List Of Non-marine Molluscs Of Canada
The non-marine mollusks of Canada are a part of the molluscan fauna of Canada (wildlife of Canada). A number of species of non-marine mollusks are found in the wild in Canada.

Mollusks
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Planorbidae
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals. Being air breathers like other ''Panpulmonata'', planorbids do not have gills, but instead have a lung. The foot and head of planorbids are rather small, while their thread-like tentacles are relatively long. Many of the species in this family have coiled shells that are planispiral, in other words, the shells are more or less coiled flat, rather than having an elevated spire as is the case in most gastropod shells. Although they carry their shell in a way that makes it appear to be dextral, the shell of coiled pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physella Gyrina
''Physella gyrina'', common name the "tadpole physa", is a species of small, left-handed or sinistral, air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Physidae. Shell description Snails in the family Physidae have shells that are sinistral, which means that if the shell is held with the spire pointing up, and the aperture is facing the observer, the aperture is on the left-hand side. The shells of ''Physella'' species have a long and large aperture, a pointed spire, and no operculum. The shells are thin and corneous and rather transparent. Distribution This species is known to occur in: * the USA - indigenous * Great Britain - introduced * Ireland - introduced * Spain References External links ''Physella gyrina''at Animalbase AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany.

Physa Skinneri
''Physa skinneri'', common name the glass physa, is a species of freshwater snail, an aquatic gastropod mollusc in the family Physidae. Description The shell of ''Physa skinneri'' is thin, narrowly ovoid, to ovoid-fusiform, with an obtusely rounded apex. The spire is blunt with up to four weakly convex whorls separated by a shallow, broadly elongated suture. Maximum shell length is about 8.8 mm (5.2 mm wide). The aperture is about 60% of the overall shell length, elongate-oval, rounded anteriorly, acute posteriorly, widest about a third of the length from the anterior end. Outer lip thin, sharp, sometimes with a white band of callus thickening within, convex in the direction of growth.

Aplexa Hypnorum
''Aplexa hypnorum'', or by the common name, the moss bladder snail, is a species of small air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Physidae, a family which are sometimes known as the bladder snails. As is true of all physids, the shell is sinistral, or left-handed. The species inhabits temporary water bodies and occurs in the Eurosiberian Boreo-temperate or possibly the Eurasian Boreo-temperate if East Siberia specimens are correctly identified. It may be Holarctic, again if North American specimens are correctly identified. Distribution * Belgium * British Isles * Czech Republic Horsák M., Juřičková L., Beran L., Čejka T. & Dvořák L.

Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=160452 on 2021-06-26 Overview These fresh water snails are present in aquariums and ponds, as well as in wild areas. They are commonly referred to as tadpole snails or pouch snails. They eat algae, diatoms and detritus including dead leaves. The populations are regulated by the abundance of food and space. They are widespread, abundant, and tolerant to pollution. These snails are common in the North Temperate to Arctic Zones and throughout the Americas, in readily accessible habitats such as ditches, ponds, lakes, small streams, and rivers. The family has been recognized since the 19th century, and yet there has been no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stagnicola Palustris
''Stagnicola palustris'' is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae, the pond snails. Taxonomy ''Stagnicola turricula'' is a synonym of ''Stagnicola palustris'', because they are not genetically independent, but ''S. curricula'' is still sometimes listed separately.
