Cladocera
The group of the Cladocera is a subdivision of the large aquatic arthropod class, the crustacea. Within these, the cladocera are contained in a group which is called Phyllopoda (gr.= leave-like feet). This is due to a phylogenetic reorganisation of the arthropod extremity which in the phyllopodes no more shows the typical pattern of distinctive parts but resembles more a leave-like structure. Cladocera mainly inhabit fresh waters, only eight species are real marine animals. Their main feeding source is phytoplankton which they filter through the hole left by the carapax. [eng] |
