Are manta rays afraid of sharks?

Manta rays are intelligent and curious creatures that have been known to interact with humans. While they are generally not afraid of humans, they may become startled or defensive if they feel threatened. Manta rays have a number of adaptations that help them to avoid predators, including their large size, powerful tails, and venomous spines. They may also use their intelligence to outsmart predators by hiding in caves or crevices, or by using their maneuverability to avoid capture.
