The eyes in Tuzoia sp. were more than twice as large to those in Tuzoia australis and show evidence of a visual cortex, but were located in a similar position, at least in dorsoventral specimens (EXPLANATION OF PLATE 4 , EXPLANATION OF PLATE 6 ).Isoxys (meaning "equal surfaces") is a genus of extinct bivalved Cambrian arthropod; the various species of which are thought to have been freely swimming predators. It had a pair of large spherical eyes (which are the most commonly preserved feature of the soft-bodied anatomy), and two large frontal appendages used to grasp prey.

Tuzoia is a rare arthropod from the upper to middle Cambrian. This specimen comes from the Balang Formation of China. This piece shows a net-like surface structure and has an enormous size.

A cladistic analysis indicates that the fuxianhuiid protopodite represents the phylogenetically earliest occurrence of substantial proximal differentiation within stem-group Euarthropoda illuminating the origin of gnathobasic feeding. Euarthropods owe their evolutionary and ecological success to the morphological plasticity of their appendages.
