Behaviour and mechanism of feeding of Lathonura rectirostris (Cladocera, Macrothricidae). [Translation from: Zoologicheskie Zhurnal 50, 1002-1010, 1971.]

The behaviour in the feeding process and the functional morphology of Lathonura rectirostris O.F. Muller - one of the widely distributed species of macrothricids - is studied. The current work is an attempt at morpho-functional analysis of the apparatus of the trunk appendages of Lathonura rectirostris O.F. Muller. This highly specialized species, the method of feeding of which basically comes to the mechanical scraping-off and collection of epiphytic single-celled algae and particles deposited on the surface of aquatic plants.
