Fishes demonstrate the greatest change throughout ontogeny in body size of all vertebrates, some becoming twelve times their original length. Panther groupers, Cromileptes altivelis, are no exception. This vast size change influences other aspects of their lives including their feeding behavior, the prey they consume, and the capabilities of the mechanisms they use to capture prey. The change in the feeding performance of the panther grouper, Cromileptes altivelis, was quantified through buccal pressure recordings and high-speed videography. From this data, we can deduce that the larger juvenile was able to generate greater negative pressure within the mouth. It appears that feeding performance improves as panther groupers increase in body size.
