Postnatal development of cartilage in the terminal airways in Otaria flavescens (Mammalia: Pinnipedia)

The presence of cartilage reinforcements in the terminal bronchioles of all marine mammals has been known since the beginning of this century ; however, their functional significance remains largely speculative. A light microscope and a digital image analysis study of the postnatal cartilage in the...
