Based on our previous studies, we found a significant shift in muscle fiber type, mitochondrial density, and aerobic efficiency as seals switch from being a non-diving pup to a deep long duration diver as an adult.
DETAILS Ambergris Caye, the slender, 25-mile-long island off the north coast of Belize, has long attracted divers, who come to explore a nearby section of the Mesoamerican Reef, the world's second-largest coral reef system.
It appears that these fishes leave the area long before divers arrive, presumably in response to sound.

These adaptations for a streamlined body facilitate efficient entry into, and locomotion in water and accordingly a greater mechanical advantage is required for respiratory movements of the relatively long sternum in divers.
