Sharks glide between the realm where the sunlight dissipates into the dark depths of the deep blue sea. With each movement towards the glistening ocean surface, the apex predator releases nitrogen-rich nutrients, where the swaying polyps are ready for the intake with glee. The beautiful courier exchange stretches across the coral reef, wherever the sharks may roam, leaving in its wake a thriving existence for all those that call the reef home. Discover the vital role coral reefs play in the very existence of sharks, and even our own, in the latest episode of “A Sea of Hope” available at the link in our bio.
