 Here, it must have fed by filtering suspended food particles, probably comparable to the trunk limb filter-feeding Cephalocarida and Branchiopoda.The exoskeletons fall into five size categories, suggesting that "T. eatoni" had a distinct breeding season, likely annually, as is the case in almost all extant crustaceans (although some amphipods have two breeding periods per year).It could live through at least four breeding seasons, and at that age reach approximately 4 cm in length.
