Whitetip reef sharks rest in groups of two to six individuals in the sandy channels at the base of Caban's wall, their slender bodies piled loosely together in the current shadow. Nocturnally active hunters, they are most easily observed resting during daylight hours but can be seen actively hunting reef fish in the late afternoon before sunset. The resident population appears stable and individuals show relatively little wariness toward divers, enabling prolonged observation at close range.
