VNS causes stimulation of the superior and recurrent laryngeal nerves and is associated with problems ranging from alteration of voice (66%), coughing (45%), pharyngitis (35%) and throat pain (28%) and hoarseness (very common) to frank laryngeal muscle spasm and upper airway obstruction (rare).
The giant manta is commonly found offshore, while the reef manta, as its name suggests, is found inshore near coral and rocky reefs. Manta rays live in the open ocean, swimming continuously through the water column instead of resting on the sea floor like other rays. Although much of their time is spent near the surface, they have been known to dive to depths of 100 feet.

Swimming next to a manta ray is a great privilege, because she is one of the giants of the ocean, the manta rays can measure eight meters and weigh 1400 kilograms, recently we learned that they are family of sharks. We know very little about the manta ray, they are a mystery, because they can't live in an aquarium. The greatest danger to the manta ray is the fishing harpoon. But the manta rays are still a really mistery.
