Gills are absent in some young organisms but develop later life as the animal grows. What is the best explanation for this? The young have a higher heart rate and thus a lower demand for oxygen. Relative to their volume, the young have more surface area across which they can transport all the oxygen they need. Relative to their surface area, the young have more body volume in which they can store oxygen for long periods of time. The young of these animals are much more active than the adult, which leads to a higher BMR (basal metabolic rate) and, therefore, a higher need for oxygen.
