OLFACTORY PRIMACY. “In amphibians, their ability to smell is derived from the superficial oscillatory movements of their buccal floor in order to establish intimate contact to their immediate surroundings be it a terrestrial or aquatic medium. The nasal respiratory function, however, is secondary as skin respiration is predominant. Amphibians, as a result, recruited the olfactory organ, as an intermittent tool for its respiratory apparatus.”
