Metallic Taste and Taste Disorders. Key points. A metallic taste in your mouth is a type of taste disorder known medically as parageusia. Common causes include new medications, pregnancy, and food allergies. In rare cases, metallic taste can be a sign of Parkinsonâs or Alzheimerâs disease.
Hi Tommy, As far as recreational diving goes, the maximum limit from PADI (a top certification agency) is 130 feet once you pass your deep diving course. If you have an open water certification, you are certified for dives down to 60 feet.
Most likely dolphins do not dive very deep though. Many bottlenose dolphins live in fairly shallow water. In the Sarasota Bay area, the dolphins spend a considerable time in waters that are less than 2 meters (7 feet) deep. Other whale and dolphin species are able to dive to much greater depths even.
