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.
In contrast, razor clams found in Alaska may grow to eleven inches in length and live to be 15 years old, due to colder water temperatures and slower growth rates. Razor clams are found primarily on the intertidal coastal beaches (those that are exposed at low tide) from a +3 foot level to a -2 foot tide level.ther areas where razor clams exist are: a series of sand spits in the mouth of Willapa Bay, the Quinault Indian Reservation and numerous small beaches north of Olympic National Park (ONP) Trail 3 at Kalaloch.
