Scapholeberis Armata
''Scapholeberis'' is a genus of small freshwater crustaceans in the family Daphniidae. The genus was described in 1858 by Schoedler and its members have a cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext ....

Daphniidae
Daphniidae is a family of water fleas in the order Anomopoda. Description Members of the family Daphniidae differ from other, similar diplostracans, such as the Macrotrichidae and Moinidae, in that the antennae of females are short and immobile. Ecology The feeding mechanism of the members of the family Daphniidae differs from that of the Macrotrichidae in allowing the animals to engage in filter feeding, rather than having to scrape food from a surface. They have evolved to fill a number of different ecological niches. '' Scapholeberis'' and '' Megafenestra'' contain species adapted to living around the surface film; '' Simocephalus'' species cling to objects while filter feeding; others have developed a pelagic lifestyle. Taxonomy The family Daphniidae contains 121 species in five genera: *'' Ceriodaphnia'' Dana, 1853 *''Daphnia'' O. F. Müller, 1785 *'' Megafenestra'' Dumont & Pensaert, 1983 *'' Scapholeberis'' Schoedler, 1858 *'' Simocephalus'' Schoedler, 1858 The members ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
