Dolphins are washing up on South Carolina beaches with no help and no answers and without state action more will die before we understand what is poisoning and weakening our coastal waters.
Along South Carolina’s coast, dolphins are washing ashore sick, injured, or dead. Most strandings involve single animals, but the pattern is steady year after year. Marine experts report that many dolphins die offshore and are carried in by tides and currents, leaving critical questions unanswered about what went wrong beneath the surface.1
Necropsies conducted by responders often reveal pneumonia, severe parasite loads, or signs of sudden internal failure. While dolphins naturally carry parasites, illness or environmental stress can allow those parasites to overwhelm the body. In some cases, dolphins appear well-fed and outwardly healthy, yet die abruptly from acute causes that remain difficult to pinpoint.12
Hidden Environmental Stress
Dolphins living close to shore face constant exposure to pollution and toxins. These contaminants accumulate in blubber over a lifetime and can weaken immune systems. During pregnancy and nursing, toxins may transfer from mother to calf, sometimes with fatal results. Responders note that young dolphins are especially vulnerable when environmental stress combines with disease.1
South Carolina typically sees dozens of dolphin strandings each year. While this is considered a normal baseline, experts warn that strandings remain one of the clearest indicators of ocean health. When dolphins struggle, it often reflects broader problems affecting fish stocks, water quality, and coastal ecosystems.2
Human Activity Increases the Risk
Boats and fishing gear remain among the leading human-related causes of dolphin deaths in South Carolina. Collisions occur most often in shallow tidal creeks and marsh edges where dolphins feed and socialize. Entanglements can lead to infection, starvation, or slow decline that ends with a dolphin stranded on shore.3
Some strandings are also linked to strand feeding, a unique hunting behavior practiced by Lowcountry dolphins. During this behavior, dolphins intentionally beach themselves to trap fish. Disruption from people or vessels can interfere with their ability to return safely to the water, increasing the risk of injury or death.4
Why South Carolina Must Act
Much of the response to stranded dolphins is carried out by nonprofit organizations that rely heavily on volunteers and limited donations. These teams perform rescues, necropsies, and data collection that are essential to understanding disease, pollution, and emerging threats. Without stable funding and statewide coordination, many strandings go undocumented and lessons are lost.12
South Carolina’s dolphins are not just icons of the coast. They are sentinels for the health of the ocean we all depend on. A funded, statewide Marine Mammal Stranding Response Program would improve rescue efforts, strengthen data collection, and help prevent future losses.
Add your name to urge state leaders to fund a statewide Marine Mammal Stranding Response Program. No dolphin should die without help, answers, or accountability.
