Blake Scott posted an article in the Huffington Post on an unusual happening in Bocas.
In the islands of Bocas del Toro, Panama, there is a beach famous for its white sand and the thousands of sea stars that once gathered there. Visitors and locals call the place Starfish Beach. “The whole bottom,” according to Dr. Peter Lahanas, “used to be covered. The seabed looked orange.”
The cushion sea star – reddish-orange with five leather-like arms – inhabits what we call a picture-perfect beach. Fine-grained sand and crystal clear seas silhouetted by a palm tree shore. Here in this edge habitat, where the land meets the ocean, sea stars behave gregariously, gathering in huge numbers to feed and breed.
In 1996, when Dr. Lahanas and his colleagues opened the Institute for Tropical Ecology and Conservation (ITEC), there were no tourists, no restaurants, no souvenir shops at the beach. It was, Lahanas explained, an “empty little beach that nobody [from the outside] really knew about.” It was an ideal site for biologists to study marine ecology, and likewise, for local fishermen to find fish and lobster.
Around 2003 and 2004, though, the tourism industry also began to discover the beach. One restaurant opened along the waterfront, and then another and another, and soon enough, the area was full of business and visitors. The sand and water, which attracted starfish for countless years, now attracted another gregarious species.
When the tourists arrived, the cushion sea stars started to disappear. Today fewer than two-dozen starfish can be found in the area.
It took millions of years for the Archipelago of Bocas del Toro to form its diverse ecosystem of sand, seagrass, mangroves, and reef; but it has taken less than twenty years of development to seriously threaten that complex environment.
The starfish’s decline is not an isolated case. A decade ago, as one researcher remembers, “you could order large, medium, or small fish for dinner in Bocas. But not any more – its just one size – small!” In a brief period of ecological time, from the early-1990s to the mid-2000s, the fishing industry collapsed. A parallel decline has also occurred with the Caribbean Spiny Lobster. The bulk of seafood now served in restaurants lining Bocas’ picturesque coastline actually comes from across the mountains, from the Pacific Ocean.
Driving these developments in Bocas are an estimated 120,000 tourists that annually visit the islands desiring seafood, service, and fun. The growth of tourism has created much-needed employment for a struggling community. As one hotel owner explained, “When I was young, there was no work in Bocas. You either had to go to Panama City, or the mainland to work on the banana plantations.” Because of tourism, Bocas’ millennial generation has found work at home, as tour guides and service workers.
But is it really necessary to trade work for ecological health? Conservation has not kept apace with the influx of foreign interest and investment. Untreated sewage, runoff, and sediment pour into the sea, suffocating reefs and other organisms dependent on clean water and light. Algal blooms flourish in the bay. Coral bleaching, already spurred by global warming, increases with local actions (and inaction.) The combination of overfishing, pollution, and climate change has turned Bocas into another tale of environmental declension. Meanwhile, tour companies, developers, and the Panamanian government promote Bocas as an untouched “paradise,” waiting to be discovered.
Visitors, it seems, are unaware of the consequences below the surface of their visit. They arrive to the beautiful islands, and quietly, the sea stars, the fish, and the lobster disappear. What type of paradise is that?
In Bocas, a small yet committed community of activists are working to combat environmental problems accompanying tourism development. They have pushed forward a progressive platform of regulations – for marine protected areas, turtle nesting grounds, and a seasonal lobster moratorium. But many of these policies remain unenforced. Why?
“The root of the disease,” in the words of the ecological thinker William Ophlus, “is not defective public policies but a defective public philosophy.” If both locals and tourists do not respect or understand the meaning behind the law, the law or policy is irrelevant.
According to ITEC researchers, the cushion sea star abandoned its namesake beach because of increasing human disturbance. Sea stars are extremely sensitive to vibrations in the water. The crowd of new visitors kicked up sand (creating turbidity); curious beachcombers would touch the animal and lift them out of the water (causing air to enter the marine invertebrates body and later float to the surface); and party-going visitors produced a cacophony of music, motors, and noise (which reverberated in the marine environment). Starfish interpreted these actions as a threat and crawled downhill into deeper water, withdrawing from their traditional breeding ground. The herd of tourists, from the perspective of the sea star, was an invasive species.
What happened at this particular tourist beach in Panama is perhaps an allegory of modern ecological folly. Contrary to carefree looking brochures and cruise ship advertisements, there is no such thing as a vacation “escape.” To sit on that beach, to swim on that reef, is to be part of nature.

Dear Tom
I read your article about the starfish and can sympathise with the content. However, while I can agree that the marine animal has disappeared due to the numbers and excesses of possibly uncaring visitors, the disappearances have happened all along the north coast of Panama.
I have lived in a small community to the east of Bocas for some fourteen years, I will not say where, for the local native people, including me, do not want hordes of visitors to come and invade the paradise. A dozen years ago the seas close by were full of fish, the sky full of pelicans, octopus and others were everywhere, butterflies abounded, as did the spider, the birds and the scorpion. Then suddenly, about six years ago, all disappeared, and now, a swim in the local seas reveals no fish, but slowly the animals are returning. There are no local visitors to destroy the environment but what has happened is that farmers and others have removed trees, either for the trees or for the pasture of cows. This has enabled mudslides and this has covered the seas making them a muddy mess, probably clogging the sands, for now the sea grass is growing where before there was clean sand. This happens at every deluge from the skies where before it didn’t.
I would suggest this is a more scientific and additional cause to your disappearances in Bocas.
Thanks
Philip
Another factor could be that also at that time, the shipping channel between Starfish Beach and the mainland reopened allowing the banana container ships to pass, changing the current sending wake from the ships to the shores. Just a thought.
