Biomphalaria Occide
''Biomphalaria'' is a genus of air-breathing freshwater snails, aquatic pulmonates belonging to the family Planorbidae, the ram's horn snails and their allies. ''Biomphalaria'' is the type genus of the tribe Biomphalariini. Both ''Planorbis'' and ''Taphius'' are synonyms for ''Biomphalaria''. The shell of this species, like all planorbids is left coiling (sinistral), but is carried upside down and thus appears to be right coiling (dextral). Species There are a suspected 35 extant species in the genus ''Biomphalaria'' in total (21 American species and 14 Old World species). However, there are a large number of invalid taxa within the ''Biomphalaria'' literature, which is likely the result of several (if not all) species of ''Biomphalaria'' being subject to various sources of intraspecific variation such as ecophenotypic variation and indeterminate shell growth. This intraspecific variation can make two individuals of the same species appear as two taxonomically distinct enti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albino
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and reddish pink or blue eyes. Individuals with the condition are referred to as albinos. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV radiation and their lack of camouflage to avoid predators. It is a common misconception that all albino animals have characteristic pink or red eyes (resulting from the lack of pigment in the Iris (anatomy), iris allowing the blood vessels of the retina to be visible); this is not the case for some forms of albinism. Familiar albino animals include in-bred strains of laboratory animals (rats, mice and rabbits), but populations of naturally occurring albino animals ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere.
