The sense of smell is poorly developed in the catarrhine primates (Catarrhini), and nonexistent in cetaceans. the less space you have in the nasal cavity the less space you have for olfactory receptors, which reduces the number of distinct smells you can detect. WebThese cats have a poor sense of smell, but have excellent vision and hearing that help them hunt in the early morning and evening hours. The lack of a standard metric for scent is the main challenge, McGann says, in comparing absolute olfactory abilities across species.
