Crocodiles Use a palatal flap, a rigid tissue at the back of the mouth that blocks the entry of drinking water. The palate has a Particular route from your nostril to your glottis that bypasses the mouth. The nostrils are closed through submergence.
Like other archosaurs, crocodilians are diapsid, Whilst their submit-temporal fenestrae are minimized.
