Rhinella lindae Rhinella lindae Rhinella lindae is a species of toad in the family Bufonidae. It is endemic to Colombia and known from its type locality, Murri in the municipality of Frontino, and from , both on the western slope of the Cordillera Occidental, Antioquia Department. The specific name "lindae" honors , an American herpetologist. However, common name Murri beaked toad has been coined for this species. The holotype, an adult female, measures , whereas the paratype male—of unknown maturity status—measures in snout–vent length. The snout is long and acuminate. In the female, tympanic annulus is present but the tympanic membrane is
Semipermeable membrane the rate and the permeability. Many natural and synthetic materials thicker than a membrane are also semipermeable. One example of this is the thin film on the inside of the egg. Note that a semipermeable membrane is not the same as a selectively permeable membrane. Semipermeable membrane describes a membrane that allows some particles to pass through (by size), whereas the selectively permeable membrane "chooses" what passes through (size is not a factor). An example of a biological semi-permeable membrane is the lipid bilayer, on which is based on the plasma membrane that surrounds all biological cells. A group of
