   Hi, Longevity Bottlenose dolphins can live to over 30 years of age and some studies have aged individuals at 50 years old when they died. As a dolphin ages, it periodically produces growth layer groups of dental material. A Dolphin’s age can be estimated by examining a sliced section of a tooth and counting these layers. Disease and parasitism As in any animal population, a variety of diseases and parasites can be responsible for dolphin deaths. Dolphins may suffer from viral, bacterial, and fungal infections. During a dolphin’s life cycle, it may develop stomach ulcers, skin diseases, tumors, heart disease, urogenital disorders, and respiratory disorders. In 1987 and 1988, more than 740 dead bottlenose dolphins washed ashore on the east coast of the United States. Scientists originally believed that the dolphin death were triggered by a naturally occurring "red tide" toxin (originating in small marine organisms called dinoflagellates) combined with bacterial and viral infections. Recent tissue analysis indicated that morbillivirus may have been a major contributing factor in most of the mortalities.
