Atelopus pachydermus and mean "thick skin". Common name Schmidt's stubfoot toad has been coined for this species, in reference to Eduard Oscar Schmidt who described the species. An alternative common name is Oyacachi jambato toad. Adult males measure and adult females, based on two specimens only, in snout–vent length. The snout is acuminate. The tympanic membrane is absent. The fingers have no webbing whereas the toes are webbed. The dorsum is covered by widely scattered or dense well-defined, rounded warts. The dorsum is yellow and has a dark brown pattern of marks, blotches and/or lines. The venter is white, sometimes orange or
Cell membrane cells to hold them together to form tissues. Fungi, bacteria, most archaea, and plants also have a cell wall, which provides a mechanical support to the cell and precludes the passage of larger molecules. The cell membrane is selectively permeable and able to regulate what enters and exits the cell, thus facilitating the transport of materials needed for survival. The movement of substances across the membrane can be either "passive", occurring without the input of cellular energy, or "active", requiring the cell to expend energy in transporting it. The membrane also maintains the cell potential. The cell membrane thus works
