Bull sharks are the primary apex predator at Cabo Pulmo and their year-round presence is a direct indicator of the reef's recovered productivity — a healthy apex predator population requires a substantial prey base to sustain it. Before the fishing ban bull sharks had nearly disappeared from this reef; their return and stable residency is cited in peer-reviewed literature as evidence of full trophic recovery. They are tolerant of divers at this site and sightings on most dives are routine.
