Once thought to be healthier than their captive cousins, wild dolphins have begun showing signs of compromised immune systems. Researchers have pinpointed ocean pollution and contamination as the main causes of this startling discovery.

For the purposes of their study, researchers studied and compared four groups of bottlenose dolphins that lived in aquariums and beyond the American coastline. Multiple wet and dry samples were collected from each of the dolphins. These samples were then subjected to testing that included hormone analyses, serum protein electrophoresis (SPEP) tests, and clinical chemistry tests.
