: “It has not been possible to study the feeding mechanism, but filtration of collected particles is certainly involved. The filter chamber, whose filtering surface are compressed by trunk limbs 3 and 4, is very well developed and the indications are that fine particles are collected. Thus the denticulation of the scrapers of trunk limb 2 is extremely fine and suggestive of sweeping rather than scraping. Its gnathobasic spines are long and slender, the anteriormost being modified for sweeping by a posterior row of fine spinules. Trunk limb 1 is relatively slender, which suggests great mobility, for which its musculature also appears suited, and the distal lobes bear slender claws. The use of these is enigmatic as they appear not to be specialized for dragging flocculent material as they are for example in

The ancestors of cladocerans presumably inhabited some shallow water bodies and had unspecialized benthic life modes (see details in Kotov 2013). With this in mind, the macrothricid-like organization is plesiomorphic as compared with a chydorid-like organization specialized to life in some particular littoral zone niches.
