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
Biological membrane fatty acid composition in accordance with differing temperatures. In animal cells, membrane fluidity is modulated by the inclusion of the sterol cholesterol. This molecule is present in especially large amounts in the plasma membrane, where it constitutes approximately 20% of the lipids in the membrane by weight. Because cholesterol molecules are short and rigid, they fill the spaces between neighboring phospholipid molecules left by the kinks in their unsaturated hydrocarbon tails. In this way, cholesterol tends to stiffen the bilayer, making it more rigid and less permeable. For all cells, membrane fluidity is important for many reasons. It enables membrane
