Description

Members of the family Daphniidae differ from other, similar cladocerans, such as Macrotrichidae and Moinidae, in that the antennae of females are short and immobile.[1]

Ecology

The feeding mechanism of the members of the family Daphniidae differs from that of 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.[2]

Taxonomy

The family Daphniidae contains 121 species in five genera:[3][4][5]

The members of the family Moinidae may also be placed among the Daphniidae.[6]
