In your study group you are discussing the clade Panarthropoda. Your classmates are trying to identify a single developmental feature that would differentiate the onychophorans from the tardigrades. What could you say to clarify this issue?The coelom of an onychophoran develops by the splitting of mesodermal bands, while the coelom of a tardigrade develops from pouches that arise from the mesodermal bands.The coelom of an tardigrade develops by the splitting of mesodermal bands, while the coelom of a onychophoran develops from pouches that arise from the mesodermal bands.The developmental pattern of the coelom of a tardigrade can vary, but an onychorphoran always has the coelom form from pouches that arise from mesodermal bands.Onychophorans cannot be distinguished by a single developmental feature.
