Final answer:
Shark Week is focusing on the sharks of the Cuban coral reefs, likely covering shark behavior, anatomy, ecosystem roles, and the importance of conservation.
Step-by-step explanation:
This year's Shark Week on the Discovery Channel is focusing on showcasing the rarely-seen sharks of the Cuban coral reefs. The main focus appears to be on demonstrating various shark behaviors, as the footage includes interactions with sharks both in-water and on-water. This educational event could also touch upon aspects of shark anatomy, their role in marine ecosystems, and the importance of shark conservation, given the threats posed by overfishing and the global demand for shark fins that have led to significant declines in shark populations.
