I read a passage that states that: 'Reptiles and amphibians swallow food whole immediately as it is caught, but in mammals food is retained in the mouth whilst it is cut up and chewed. Mammals have a palate that seperates the air path (nasal cavity from the mouth. This allows food to be retained in the mouth rather than swallowed whole between breaths.'

Does this mean that a reptile's nasal passage is not seperate to the mouth, or is it that they don't have a bone separating them and have flesh instead? If they are seperated, why are they forced to swallow whole?

Thank you

sorry no-one seems to know the answer to your question.
