Sphaerium Scaldianum
''Sphaerium'' is a genus of very small freshwater clams, aquatic bivalve molluscs in the family Sphaeriidae, known as the fingernail clams. The small clams in this genus are unusual in that many of them, such as '' Sphaerium corneum'', can climb around underwater on aquatic plants, using their long and strong foot.

Sphaerium Corneum
''Sphaerium corneum'', also known as the European fingernailclam, is a very small freshwater clam, an aquatic bivalve mollusk in the family Sphaeriidae, the fingernail clams. Description The shell is fairly globular and can grow up to 9–13.5 mm in size. The color of the shell is usually a brown to gray with the juveniles being a yellow color. Their shells exhibit striae, thin parallel rows of elevated lines. Revisiondate: 3/23/2007 Ecology These small clams are found in shallow, freshwater habitats with slow moving waters, including freshwater lakes, rivers and creeks. As with most bivalves, ''Sphaerium corneum'' is mainly a filter feeder and thus prefers more eutrophic waters that provide a greater food source. These clams have exhibited a unique ability to climb up plants and structures around their habitat to find more optimal locations for feeding. They also are known to deposit feed in times of low current or food availability. This species has shown a preference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Loris S
Loris is the common name for the strepsirrhine mammals of the subfamily Lorinae (sometimes spelled Lorisinae) in the family Lorisidae. ''Loris'' is one genus in this subfamily and includes the slender lorises, ''Nycticebus'' is the genus containing the slow lorises, and ''Xanthonycticebus'' is the genus name of the pygmy slow loris. Description Lorises are nocturnal and arboreal. They are found in tropical and woodland forests of India, Sri Lanka, and parts of southeast Asia. Loris locomotion is a slow and cautious climbing form of quadrupedalism. Some lorises are almost entirely insectivorous, while others also include fruits, gums, leaves, and slugs in their diet. Female lorises practice infant parking, leaving their infants behind in trees or bushes. Before they do this, they bathe their young with allergenic saliva that is acquired by licking patches on the insides of their elbows, which produce a mild toxin that discourages most predators, though orangutans occasionally ea ...

Sphaerium Beckmani
''Sphaerium beckmani'' is an extinct species of fossil freshwater pea clams from the Late Cretaceous deposits of North America. This species was first described by the American paleontologist Loris Shano Russell in 1976. The specimens were collected by the American paleontologist Karl M. Waage from 1961 to 1962 from the Hell Creek Formation of eastern Montana. The locality is dated to the late Maastrichtian Age (around 66.0 to 72.1 million years ago). Since the Sphaerium beckmani had a hard shell as it was a pea clam it was used for the protection of themselves from predators and severe conditions which is what the Phylum Mollusca Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks ().
