Cucumericrus decoratus is a species of putative radiodont known from a few poorly preserved specimens.[1][2] Only fragments of trunk cuticle and corresponded appendages had been revealed, while important radiodont features such as frontal appendages are unknown in this species.[2][3] The trunk cuticle possess irregular wrinkles[1] and may had been soft in life.[4] Each of the trunk appendage compose of a dorsal flap-like element and a ventral stubby leg with unknown distal region,[1] structurally comparable to the trunk appendages of gill lobopodians (dorsal flaps and ventral lobopods) and euarthropod biramous appendages (flap-like exopod and limb-like endopod).[3][5] The legs have been interpreted as somewhere between annulated lobopod legs and segmented arthropod legs.[4][5]
